Injector Fitting Kit suitable for Isuzu 4JJ1 – 2014 Onwards

In 2014, Isuzu updated the rocker cover design on the 4JJ1 engine. This change also altered the injector seals and gaskets required when fitting injectors. This kit is designed specifically for 2014+ models with the updated rocker cover.

🚗 Suitable for:

• Isuzu D-MAX 3.0L 4JJ1 (2014 onwards)

• Holden Colorado 3.0L 4JJ1 (2014 onwards)

• Isuzu MU-X 3.0L 4JJ1 (2014 onwards)

📦 What’s in the kit:

• 1 × Rocker cover gasket (pre-2014 design)
• 4 × Leak Off Washers
• 4 × Injector Solenoid Seal
• 4 × Injector Seal

🛠️ Fitment details:

• For vehicles built 2014 onwards with the revised rocker cover

• Pre-2014 models require a different kit – check your VIN or build date before ordering

• Essential when fitting new or reconditioned injectors

💡 Why you need this kit:

• Ensures proper sealing on updated 2014+ rocker cover design

• Stops combustion and oil leaks (“blow-by”)

• Protects injectors from premature wear and carbon build-up

• Peace of mind when replacing injectors – seals and gaskets should never be reused
