If you are looking for a Mitsubishi 4N15 engine for sale, you most likely drive a newer Triton or L200, a Pajero Sport or Montero Sport, a Delica D:5 or a Fiat Fullback. These are modern diesel pickups and SUVs, and the 4N15 is a much more sophisticated engine than the old 4D56 it replaced. When it fails, the repair bills from a dealer can be frightening. A good used engine is often the sensible way out.

Why a Mitsubishi 4N15 Engine for Sale Makes Sense
The 4N15 is a 2.4 liter four cylinder turbo diesel that Mitsubishi introduced around 2015 for the fifth generation Triton and the new Pajero Sport. It has an aluminum block, twin cams, common rail injection, a variable geometry turbo and MIVEC variable valve timing. It is quieter, cleaner and much more powerful than the 2.5 liter 4D56 it replaced.
The trade off is complexity. More sensors, more electronics, and emissions equipment like a diesel particulate filter. When something serious goes wrong inside, a dealer will often quote a new engine at a price that makes owners think about selling the vehicle. A Mitsubishi 4N15 engine for sale from a low mileage donor is usually a far cheaper fix.
If you are comparing a rebuild with a used engine, our article on rebuilt vs used engine goes through the pros and cons.
Mitsubishi 4N15 Engine Specifications
Mitsubishi sold the 4N15 in more than one state of tune, so the power and torque figures below are a range.
| Specification | Mitsubishi 4N15 |
|---|---|
| Layout | Inline four cylinder turbo diesel, DOHC, 16 valves |
| Displacement | 2,442 cc (2.4 L) |
| Bore x stroke | 86.0 mm x 105.1 mm |
| Block | Aluminum |
| Cylinder head | Aluminum, twin cam |
| Valve timing | MIVEC variable valve timing |
| Injection | Common rail direct injection |
| Turbo | Variable geometry turbocharger, intercooled |
| Compression ratio | About 15.5:1 |
| Power | About 150 to 204 PS (110 to 150 kW) depending on tune |
| Torque | About 380 to 470 Nm depending on tune |
| Timing drive | Chain |
| Emissions | DPF on most versions, AdBlue on some later models |
| Years built | 2015 to present |
The low 15.5:1 compression ratio is unusual for a diesel and part of why the 4N15 runs smoothly and quietly. The wider family, including the 2.2 liter 4N14, is listed on the Mitsubishi 4N1 engine page.
What it feels like to drive
The higher output versions pull strongly from low revs and make the Triton and Pajero Sport feel genuinely quick for diesel utes. The lower tune versions are still far stronger than the old 4D56. Towing is where the 4N15 really shows its value, which is why many fleet owners look for a Mitsubishi 4N15 engine for sale rather than switching brands when an engine fails.
Which Vehicles Use the 4N15?
- Mitsubishi Triton and L200 (fifth and sixth generation in many markets)
- Mitsubishi Pajero Sport and Montero Sport (third generation)
- Mitsubishi Delica D:5 diesel (later models)
- Fiat Fullback
- Ram 1200 in some Middle East markets
The Mitsubishi Triton is by far the most common home for this engine. If your vehicle is on this list and the engine code reads 4N15, a Mitsubishi 4N15 engine for sale should be a direct replacement, as long as the year and emission version match.
The engine code is stamped on the block, and you can also confirm it from the VIN. Send us the VIN and we will check it for you.
Matching the Right 4N15 to Your Vehicle
With a modern engine like this, the details matter.
- Power output. High and low output versions use different turbo settings, software and sometimes injectors. Matching your existing tune keeps your ECU happy.
- Emission standard. Euro 4, Euro 5 and Euro 6 versions exist depending on market. Euro 6 engines may use AdBlue (SCR). Wiring, sensors and exhaust parts differ.
- Two wheel drive and four wheel drive. Some accessory brackets and sump details can differ.
- Year changes. Updates were made through the production run, especially around facelifts.
Your existing ECU and immobilizer usually stay with the vehicle. Some injectors need their codes entered with a scan tool after fitting, which a good diesel shop can do. We check the details on every Mitsubishi 4N15 engine for sale before you pay.
7 Checks Before You Buy a Mitsubishi 4N15 Engine for Sale
1. Confirm the code, year and emission version
Euro 4, 5 or 6, high or low output. A photo of the engine and the donor VIN settles it.
2. Ask about the mileage and service history
These engines are young, so low mileage donors are common. Ask for the odometer reading of the donor vehicle.
3. Ask why the donor was scrapped
A crash damaged vehicle with a running engine is ideal. An engine pulled because of a fault is not.
4. Check for oil and coolant mixing
Milky oil or oil in the coolant points to head gasket or oil cooler trouble.
5. Ask about the turbo and injectors
Common rail injectors and variable geometry turbos are expensive. Ask if either has been replaced or shown problems.
6. Ask what is attached
Turbo, injectors, fuel pump, intake, EGR and wiring. A complete engine saves a lot of money on a modern diesel.
7. Get the warranty in writing
A seller confident in a Mitsubishi 4N15 engine for sale will put the terms in writing. Our used engine warranty page explains ours.

Common 4N15 Problems
The 4N15 is a good engine overall, but these are the issues that bring owners to us looking for a Mitsubishi 4N15 engine for sale.
DPF clogging and oil dilution
Short trips stop the particulate filter from cleaning itself. The engine then injects extra fuel to burn it off, and some of that fuel ends up in the oil. Thin, diluted oil wears bearings and the timing chain. Oil level that rises instead of falling is a warning sign.
EGR and intake carbon build up
Like most modern diesels, the EGR system feeds soot into the intake. Over time it clogs the EGR valve and intake, causing poor running and warning lights.
Injector problems
Poor fuel or water in the fuel damages common rail injectors quickly. A failed injector can wash down a cylinder or damage a piston.
Turbo faults
Sticking variable vanes cause limp mode and loss of power. Oil starvation from diluted oil can wreck the turbo bearings.
Overheating damage
An aluminum block engine does not like running hot. Coolant leaks or a failed water pump can warp the head and damage the gasket.
Bearing failure
Most serious 4N15 failures we hear about are bottom end bearing failures, usually linked to diluted oil, low oil level or long oil change intervals. Once a bearing spins, a replacement engine is usually the only practical answer.
Repair or Replace?
Before buying any engine, get a proper diagnosis with a scan tool.
- Usually a repair: a blocked DPF or EGR, a faulty sensor, a single bad injector caught early, a sticking turbo actuator, a coolant leak.
- Usually a replacement: a spun bearing or bottom end knock, a holed piston, serious overheating damage, metal in the oil.
If your engine is in the second group, a used Mitsubishi 4N15 engine for sale is almost always far cheaper than a new engine from a dealer. If it is in the first group, fix it and save your money.
What a Mitsubishi 4N15 Engine for Sale Costs
Because it is a modern engine, the 4N15 costs more than older diesels, but a used one is still far below the price of a new crate engine. The price depends on:
- Year, output and emission version
- Long block or complete with turbo, injectors and fuel system
- Mileage of the donor
- Shipping distance and port or door delivery
Send us your VIN and country, and we will give you one clear shipped price for a Mitsubishi 4N15 engine for sale. For the full cost of the job, including labor and coding, read our guide to replacement engine cost. Our long block vs short block article explains what different quotes include.
What Comes With Our Mitsubishi 4N15 Engine for Sale
Every Mitsubishi 4N15 engine for sale from us is a fairly used engine from a running vehicle, often a low mileage donor. Depending on stock, we supply a long block or a more complete engine with turbo and injection system. We send photos of the exact engine and list what is attached before you pay.
Each engine comes with a 6-month limited warranty. Labor is not covered. We choose low mileage used engines whenever possible and tell you the donor mileage.
How We Check Each Engine Before It Ships
- Engine code, year and emission version confirmed
- Compression checked on all four cylinders
- Oil checked for fuel smell, coolant or metal
- Turbo checked for play and oil on the compressor side
- Engine turned by hand to feel for tight spots
- Openings sealed, fluids drained, engine strapped to a pallet
A Mitsubishi 4N15 engine for sale that fails these checks does not leave us.
Used, reconditioned or rebuilt?
A used engine comes from a running vehicle and goes back in after checks. A reconditioned engine has had some work such as gaskets and seals. A rebuilt engine has been stripped and had worn parts replaced. Our remanufactured vs rebuilt engine guide explains the difference. We tell you clearly which you are buying.
Installing a Used 4N15: Notes for Your Mechanic
In the Triton and Pajero Sport, most shops lift the engine out the top, with or without the gearbox. It is a normal job for a diesel workshop with a scan tool. While the engine is out, do these:
- Check and clean the intercooler and pipes, especially if the old engine failed internally
- Replace the oil cooler or flush the oil lines if there was metal in the old oil
- Check the DPF condition, and clean or replace it if it is blocked
- New fuel filter, and drain and clean the tank if water got in
- Water pump, thermostat and coolant hoses checked
- Engine mounts
- Enter injector codes and reset learned values with a scan tool
- Fresh oil of the correct low ash specification, then change it again after the first 1,000 km
The intercooler and oil cooler points matter. If the old engine shed metal or oil into the system, it can be pulled straight into the new one. Ask your mechanic for a written quote before you order a Mitsubishi 4N15 engine for sale.
Looking After the Engine After the Swap
The first month after the swap tells you most of what you need to know. Check for leaks under the vehicle, watch the temperature gauge, and scan for any stored codes after the first week of driving. Small things like a loose sensor plug are easy to fix early and annoying to chase later.
Give it regular longer drives so the DPF can regenerate. If the dash shows a regeneration is in progress, do not switch off mid cycle if you can avoid it. Check the oil level every week or two, and if it rises, get it looked at.
Use the correct low ash oil, change it on time, and do not skip fuel filter changes. Buy diesel from busy stations. Look after a Mitsubishi 4N15 engine for sale like this and it should give you many years of work.
Keep a record
Write down the install date, the odometer reading and every service. It helps with any warranty claim and adds value when you sell.
Model by Model Notes
Triton and L200
The most common home for the engine. Work utes often do short trips and heavy towing, which is tough on the DPF and oil. Tell us whether you have the high or low output version.
Pajero Sport and Montero Sport
Family SUVs that often do school runs and city driving. DPF and oil dilution issues show up more on these. Later models may have AdBlue.
Fiat Fullback
Mechanically a Triton, but parts sourcing can be harder. A Mitsubishi 4N15 engine for sale from a Triton will usually suit, but send us the VIN so we can confirm the version.
Delica D:5
The diesel Delica uses the 4N15 in a transverse layout with different accessories. Tell us up front if you have a Delica so we match it properly.
Signs Your 4N15 Is in Trouble
Modern diesels usually warn you before they fail. Watch for these:
- Oil level rising between changes, or oil that smells of diesel
- Frequent DPF warning lights or regenerations that never seem to finish
- A knock from low in the engine, especially when warm
- Low oil pressure warnings at idle
- Blue or white smoke that does not clear once warm
- Coolant going missing with no visible leak
- Limp mode that keeps coming back after the codes are cleared
If you see a rising oil level, act quickly. Diluted oil is behind many of the bearing failures we hear about, and catching it early can save the engine. If the engine is already knocking, stop driving it and get a quote on a Mitsubishi 4N15 engine for sale before the damage spreads to the turbo and oil cooler.
Used Engine vs a New Engine From a Dealer
A brand new engine from a dealer is the most expensive option, and in many countries there is a long wait for one. For a vehicle that is a few years old, the cost of a new engine plus labor can come close to what the vehicle is worth.
A used engine from a low mileage donor costs a fraction of that, and because the 4N15 has only been around since 2015, many donor engines have done relatively few kilometers. You still get a factory built engine, just one that has already run in a vehicle. When you buy a Mitsubishi 4N15 engine for sale from us, you get photos of the exact engine, the donor mileage we have on record, a compression check and a written 6-month limited warranty.
Whichever way you go, ask the same questions: what is the mileage, how was it tested, and what happens if it is bad. A seller who answers those clearly is one you can work with.

4N15 vs 4D56 vs 4M41
The 4D56 is the old 2.5 liter diesel used in earlier Tritons, L200s and Pajeros. Simpler and cheaper, but much less powerful and not a swap into a 4N15 vehicle. Our Mitsubishi 4D56 turbo engine for sale guide covers it.
The 4M41 is the 3.2 liter diesel from the Pajero and Shogun. Big torque, but a different vehicle entirely. See our Mitsubishi 4M41 engine for sale guide.
For any vehicle that came with a 4N15, the simplest and most reliable answer is a matching Mitsubishi 4N15 engine for sale.
