Do I need to replace injector washers every time?
Yes. Injector washers are single-use crush seals. Re-using them risks blow-by and injector seat damage.

Yes — OEM Isuzu part numbers 8-98181540-0 and 9-09566111-0.
Will these fit all 4JJ1 engines?
Yes — fits all common-rail 4JJ1 engines in D-MAX, MU-X, Colorado RC and Rodeo RA7.
Do you ship quickly?
All orders ship Express from Australia — usually same or next business day.
👉 Don’t risk reusing old washers — grab a fresh set and do the job right the first time.
