4N15 +30% Injector Nozzles | MCR Performance | Mitsubishi Triton MQ, MR 2.4L 2015 On (Set of 4)

Quick check: your injector is Denso 295050-1760. Pajero Sport QE and QF run the same 4N15: see the Pajero Sport listing. A 4D56 Triton (ML, MN) takes the 4D56 nozzle set, not this one.

• 4 x MCR Performance +30% nozzles for the 4N15 Denso 295050-1760 injector

Nozzles only. Not complete injectors. Seat washers, seals and injector bodies are not included.

Nozzles if your injectors are healthy, you have a bench or a workshop with one, and you want the cheapest way to +30. The nozzle swap needs the injector stripped, the nozzle fitted, the set flow matched and leak-off checked, then reassembled. It is not a driveway job.

Complete injectors if your set is tired, you want a matched set built and tested on our Hartridge, or you want it done once: 4N15 +30 Injectors on genuine Denso bodies.

We can fit them for you. Send your injectors in and we will fit the nozzles, match the set and return them with a bench report. Message us for pricing.

Standard replacements instead? See the genuine Denso 4N15 set. Want more? See the 4N15 +50 nozzles.

MCR size their nozzles by boost pressure, not by a flow percentage. Flow percentages depend on the bench, the test plan and the rail pressure, so two shops will never agree on a number. Boost is a real figure you can state. MCR's band for the S032 is up to 45 psi.

• Factory turbo: yes, with a tune. A conservative map still picks up torque and leaves headroom for a turbo later.
• Turbo upgrade: where the nozzles earn their keep. See the 4N15 44mm turbo and the 4N15 intercooler upgrade.
• Rail pressure: on a tuned 4N15 the factory rail relief valve is the next thing to hold pressure back. See the MCR rail blank.
• DPF fitted: the nozzles work with the DPF in place and a tune to suit. Any change to emissions equipment must comply with the laws that apply to your vehicle and its use.

• Fit on a common rail bench. Strip the injector, fit the nozzle, check shim stack and needle lift, flow test and leak-off test, match the set.
• Refit with new seat washers and seals.
• The existing compensation code on the body stays valid after a nozzle change. Enter it as normal and run the injector learn.
• ECU remap required. The factory map does not know the nozzle changed.
• Clean-room practice. One speck of grit is enough to stick a needle.

MCR is the Thai performance nozzle house behind every modified injector set we build. Consistent hole geometry from set to set means a tuner can hit the same map on the next truck. These are the same nozzles we fit to our own sets.

Usually in stock and shipping same or next business day. If we are waiting on a shipment from MCR, allow 1.5 to 3 weeks and we will confirm an ETA. On a deadline? Message us before ordering.

These are modified performance nozzles, not a standard replacement part. Flow percentages are nominal and vary with rail pressure, pulse width and test bench. Fitting them changes the flow characteristics of the injector from original OEM specification.

Any change to emissions equipment or calibration must comply with the laws that apply to your vehicle and its use. Off-road and competition use where permitted.

It is the customer's responsibility to verify injector compatibility before fitting.

Q: Are these complete injectors?

A: No. Nozzles only. They must be fitted to Denso 295050-1760 bodies on a common rail bench.

Q: Do I need a tune?

A: Yes. An ECU remap is essential to use the extra fuel and keep smoke and EGTs under control.

Q: Will these work on the stock turbo?

A: Yes, with a tune written for it. They come into their own behind the 4N15 44mm turbo.

Q: Will the compensation codes change?

A: No. A nozzle change does not generate new codes. Re-enter the code on the body after refit and run the injector learn.

Q: Should I choose +30 or +50?

A: +30 suits a tuned Triton on the factory or a mildly upgraded turbo. +50 is for a turbo upgraded build with a stroker shaft budgeted in. If you are not planning major supporting mods, +30 is the better buy.

Q: Can I fit them myself?

A: Only if you have a common rail test bench. Otherwise send the injectors to us or a diesel shop with one.
