Factory-spec replacement injectors for stock 4JJ1 engines:

• Brand New Denso units
• Correct 5F compensation code
• Factory-fit—no modification required
• High accuracy for cold starts & idle stability

• Isuzu D-MAX 4JJ1-TC — 2006–2012
• Holden Colorado RC 4JJ1-TC — 2008–2012
• Holden RA7 Rodeo 4JJ1-TC — 2007–2008

Check compensation code on injector: should start with 5F. Send VIN/reg if unsure and we'll verify.

Choose your install kit based on what you need:

Option 1 — Complete 4JJ1 Fitting Kit (Recommended):

Full genuine kit with copper washers, O-rings, seals and hardware. The proper way to do the job.

Option 2 — Nozzle Washer Kit Only (Budget):

Bare minimum if you're only replacing copper washers. Not recommended unless you know what you're doing.

Essential — 4JJ1 Injector Lines:

Reusing old injector lines is the #1 cause of post-install leaks. Always replace when fitting new injectors.

💡 Pro Tip: Always use new fire washers, seals and injector lines. Prime fuel system before cranking. Check return line assembly for leaks after install.

Q: How do I confirm these are the correct injectors?

A: Match the compensation code on your existing injectors—should begin with 5F. Or send your VIN/reg and we'll verify compatibility before dispatch.

Q: Are these new or refurbished?

A: These are 100% brand new Genuine Denso injectors—never reconditioned, not exchange units.

Q: Will +30 or +50 injectors work without tuning?

A: No—performance injectors require ECU tuning to maintain fuel control and avoid smoke/over fueling. Standard injectors (this listing) do not require tuning.

Q: Do these suit DPF models?

A: No—these suit pre-DPF 2006–2012 4JJ1 engines only. DPF models use different injectors with different part numbers.

Q: What's the difference between the complete fitting kit and washer kit?

A: Complete kit includes copper washers, O-rings, seals and all hardware for a proper install. Washer kit is copper washers only—bare minimum for budget installs.

Q: Do I need to replace injector lines?

A: Strongly recommended. Old lines can leak and contaminate your new injectors. Button above to add them to your cart.
