YD25 +30% Injector Nozzles | MCR Performance | Nissan Navara D40, Pathfinder R51, Denso 095000-6250 (Set of 4)

Quick check: your injector is Denso 095000-6250 (Nissan 16600-EC00A). A later D40 with 295050-0300 is a different injector generation and takes a different nozzle: message us. A D22 with 095000-6240 takes the D22 nozzle set. None of those are this part.

The D40 ran more than one injector over its life, so check the number on the injector body rather than the build year. Not sure? Add your VIN or State and Rego to the order notes and we will confirm before dispatch.

• 4 x MCR Performance 947S +30% nozzles for the Denso 095000-6250 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 or you want it done once: the genuine Denso 095000-6250 set is available standard or with these +30 nozzles fitted and matched on our bench.

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.

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. Tell us your turbo and boost target and we will confirm the nozzle before you order.

• Factory turbo: yes, with a tune. A conservative map still picks up torque and leaves headroom for a turbo later.
• Rail pressure: on a tuned YD25 the factory rail relief valve is the next thing to hold pressure back. See the MCR rail blank.
• Compliance: any change to emissions equipment or calibration 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.

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 095000-6250 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 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: My D40 has 295050-0300 injectors. Will these fit?

A: No. That is a different injector generation and takes a different nozzle. Message us with your injector number.

Q: Will these fit a D22?

A: No. The D22 runs the 095000-6240 injector and takes the D22 nozzle set.

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.
