Review on Enhance Engine Performance with Spectre Performance SPE-42851 Black Push-In Breather by Maurice Harvey

Revainrating 1 out of 5

Will not fit standard valve covers

I tried using this breather on standard GM valve covers but it was too big. Maybe it's suitable for reproduction covers? I do not know. Do not buy if you intend to use it with standard GM valve covers.

Pros
  • Grommet included
Cons
  • Retrofit
