Review on FEL PRO MS 90505 Plenum Gasket by Chris Hanson
works perfectly! for parts
Just installed them on the upper intake manifold on my 3.4L 04 Impala a few days ago, the plastic lugs snap into their respective manifold holes to ensure they don't move when the manifold is lowered. No problem.
Pros
- Gaskets
Cons
- Security
