4-346 Fuel Injector Rebuild Seal O-Ring Kit

Perfect and complete set! Did all 6 injectors.

great fit. worked very well

Did the knock sensors and major tune up on the Lexus Rx300 so of course it was recommended to change O rings on fuel injectors, got everything back together and started her up and gas went everywhere, every single injector leaked so now the manifold has to come off to change the back ones, we figured out it was the O rings because when we changed the front O rings back to the ORIGINAL rings that have 125K+ miles on them, they stopped leaking. In the beginning we were actually convinced somehow we needed to change the entire injector (that had no issues when we started). This is a hell of a lot of extra, unnecessary, bull pucky to have to go through over some useless crap people are trying to peddle as parts.

All was good except the o ring that goes on the very top and the bottom are not thick enough. They don't seat very well in the fuel rail or the injector ports. Need to be thicker o ring. I found some at harbor freight and they worked awesome.

Purchase this fuel injector seal kit for a 1998 toyota 4runner and it was missing one set of seals for one injector.

Excelente

These rings solved my injector problem, no more gas leaks. By the way, great price and were delivered on time. Thanks'!
