Isuzu D-MAX 4JJ1 Injectors - 2012-2016 - Pre DPF - 095000-9960 / 095000-8340

🔹 Standard Flow (OEM Replacement)

• Factory-spec Genuine Denso injectors
• Direct OEM replacement for stock builds
• Maintains factory fuel delivery and economy
• No tuning required — straight in

🔹 Modified +30 Performance

• Genuine Denso bodies with MCR upgraded nozzles
• Upgraded fuel delivery for modified builds
• Suits upgraded turbos with a proper tune
• Supports moderate power increases
• ECU tuning required

🔹 Modified +50 High-Flow

• Genuine Denso bodies with MCR high-flow nozzles
• Maximum fuel delivery for serious power
• Built for 250+ RWHP setups
• Wants an aggressive turbo, intercooler and supporting mods
• Professional ECU tuning mandatory

⚠ Important: +30 and +50 need a proper tune to run safe. Running modified injectors without one over-fuels the engine and gets ugly fast. Don't go in raw.

• Isuzu D-MAX 3.0L 4JJ1-TC — 2012 to 2016 (Pre-DPF models only)

✅ Fitment check: Look at the compensation code on your injector plug — it should start with '72'. Not sure? Drop your VIN and rego in the cart notes and we'll confirm before it goes anywhere near your engine.

⚠ PRE-DPF ONLY: These suit 2012–2016 pre-DPF models only. Not compatible with DPF-equipped vehicles.

Don't go in dry. Sort the supporting bits before install day:

• Injector Washer & O-ring Kit (essential) — copper washers for a proper seal. Never reuse old washers; they won't seal the second time round.
• 4JJ1 Injector Lines 2012–2016 (essential) — reusing tired old lines is the #1 cause of a messy post-install leak. Always replace when fitting fresh injectors.

💡 Pro tip: Always use new copper washers and injector lines. Injector coding is required — compensation codes must be programmed to the ECU with diagnostic gear.

Multiple part numbers due to supersessions and regional variations — all refer to the same genuine Denso injector. Packaging may vary from photos, but the injectors are the exact same genuine parts.

Professional installation recommended.

• Injector coding required — new compensation codes must be programmed to the ECU
• Torque specs critical — follow factory torque specs for injector clamps
• Fuel system priming — proper bleeding and priming essential
• Return line inspection — check condition of return lines and seals
• Pro install strongly recommended — especially for +30/+50 variants

⚠ ECU Coding Required: Compensation codes must be programmed into the ECU during install. Needs diagnostic equipment and is best left to a qualified diesel tech.

For off-road / competition use only (modified +30/+50 variants). Modified injectors require ECU tuning and may affect compliance. Check local regulations before purchase.

Q: Genuine Denso or aftermarket?

A: Genuine Denso injector bodies. Standard flow is fully OEM. +30/+50 use genuine Denso bodies with MCR upgraded nozzles.

Q: What's the difference between Standard, +30 and +50?

A: Standard = OEM flow. +30 = 30% more fuel delivery (MCR nozzles) for moderate builds. +50 = 50% more (MCR nozzles) for serious power (250+ RWHP).

Q: Do I need a tune for standard injectors?

A: No — standard flow is a direct OEM replacement, straight in, no tune. +30 and +50 both need professional ECU tuning.

Q: Will these fit my 2017+ D-MAX?

A: No — these are for 2012–2016 pre-DPF only. Later DPF-equipped models use different injectors.

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

A: Check the compensation code on your injector plug — it should start with '72'. DPF models have different codes. Send your VIN if unsure.

Q: Do injectors come with seals/washers?

A: No — grab the washer kit separately (see "What You'll Want on Hand"). Never reuse old washers.

Q: Can I install these myself?

A: Pro install strongly recommended. Injector coding needs diagnostic equipment to program the compensation codes into the ECU.

Q: What power can I expect with +30 or +50?

A: Depends on your full setup. +30 suits 180–220 RWHP builds, +50 suits 250+ RWHP. Both want supporting mods — turbo, intercooler, exhaust, tune.

Q: New or remanufactured?

A: Brand new genuine Denso injector bodies. Never reconditioned, never touched.

Q: How do I verify fitment?

A: Leave your VIN and rego in the cart notes before checkout, or get in touch first. We'll confirm compatibility.
