4JJ3 OEM Injector Fit Kit (Seal Kit)
Ensure a reliable seal for your 4JJ3 injectors with this OEM Injector Fit Kit (Seal Kit), designed specifically for Isuzu D-MAX, MU-X and Mazda BT-50 models (2020–Current).
These injector sealing components are positioned between the injector and cylinder head, playing a critical role in maintaining proper combustion sealing. Worn or incorrect seals can result in injector noise, combustion blow-by and sealing failures that cannot be corrected by re-torquing alone.
This kit includes a complete set to suit your engine, manufactured to meet OEM standards, ensuring correct fitment, durability and long-term reliability.
Included:
- Nozzle
- Nozzle Washer
- Tappet Cover Seals
- Tappet Cover Seal Gasket
