Why We Do Not Sell a +30 for This Injector

Plenty of places will happily sell you a +30 injector for this model. We think it is a waste of your money, and the bench data is why.

The standard 095000-9960 / 095000-8340 injector only flows roughly 105 mmΒ³ at 1800 bar and 1450 Β΅s on our Hartridge Sabre CRi Expert. That is a small injector nozzle to begin with, so 30% of it is a small gain: about 137 mmΒ³, which runs out of fuel the moment you bolt on a decent turbo. OurΒ MCR +60 flows 165 mmΒ³ at the same test point. Same install time, same downtime, close to double the extra fuel over standard.

Standard and MCR +60 figures are our own bench readings at 1800 bar and 1450 Β΅s. The +30 bar is calculated from the standard reading for comparison, since we do not sell one. Figures are nominal and vary with bench, rail pressure and test duration.


What You Will Need for Installation

Injector Washer Kit

Copper washers for proper sealing. Never reuse old washers, they will not seal properly a second time.

Add Injector Washer and O-Ring Kit

4JJ1 Injector Lines, 2012-2016

Reused injector lines are the number one cause of post-install leaks. Always replace when fitting new injectors.

Add 4JJ1 Injector Lines 2012-2016

Injector compensation codes must be programmed into the ECU during installation using diagnostic equipment.

Frequently Asked Questions

Q: Are these genuine Denso injectors or aftermarket?

A: Genuine Denso injector bodies. The standard set is fully OEM. The +60 and +75 sets use genuine Denso bodies fitted with MCR performance nozzles.

Q: Why do you not offer a +30?

A: The standard injector on this model only flows roughly 105 mmΒ³ at 1800 bar / 1450 Β΅s, so a +30 gets you to about 137 mmΒ³ for the same install, coding and downtime cost as a proper upgrade. Our +60 flows 165 mmΒ³ at the same test point. See the bench data above.

Q: Do I need a tune?

A: The standard set is a direct OEM replacement and needs no tune. The +60 and +75 sets require professional ECU tuning. Fitting bigger nozzles without a calibration to suit is how you end up with smoke and high EGTs instead of power.

Q: Will these fit my 2017 or later D-MAX?

A: No. These suit 2012-2016 pre-DPF models only. DPF models run a different injector.

Q: How do I know my truck is pre-DPF?

A: Check the injector compensation code on your plug, it should start with 72. Send us your VIN if unsure.

Q: Do the injectors come with washers?

A: No, add the washer kit above. Never reuse old washers.

Q: Which size do I need, +60 or +75?

A: Message us your boost figure and what turbo you are running and we will tell you straight.
