• O Rings made of more durable FKM (VITON) material
  • Ring Seals made of Nylon material
  • Both Resistant to higher temperatures

Bought this as a preventative measure after cleaning out the solenoids. Old o-rings looked pretty good but since my car is 11 years old, why not? I don't wanna face any more VANOS issues. They fit a slight bit tighter than the old black ones, apparently this green material is better. I also got o-rings for the non-return valves I cleaned, those are a bit harder to get to. Will update if I find these leaking.

All there, all 4 gaskets.
