  • Fixed the spark plug wells oil problem
One day on the highway, my engine light came up and engine almost stalled, had to exit as fast as I can and stopped to check the engine, found the spark plug wells filled with engine oil, cut the sparks. Replaced this set of engine gaskets, and have not oil leak in couple weeks.

  • These O-rings are Thicc
Reasonably priced however the thickness category... The green injector o-rings are a little too thick. Even with a little grease or oil these did not fit back into the fuel rail I needed them to fit in. Factory B-series injectors and Skunk2 fuel rail, even tried on a factory B18C rail and they didn’t fit. The rest of the grommets/gaskets worked great. ... show more

  • Good for the price
Does not come with the o-ring for the injectors that goes into the intake manifold. Other o-rings fit nicely into the fuel rail with some silicone grease.
