Review on 🔧 FEL-PRO MS 95392 Intake Manifold Gasket Set: Premium Quality for Efficient Performance by Adam Boudreau

The second non-use of cork gaskets. No no no. Also, get graphite port gaskets (Dorman 615-310), not these fiber gaskets. At one point my fiber spacers flaked off and started sucking air into cylinders #5 and #6 (the pics were rotten). This caused a very lean mixture in those two cylinders, which inevitably caused the O2 sensors to rich all cylinders to maintain proper stoichiometry. Back to Graphoil.
