GrimmSpeed Enlarged Bore Intake Manifold to TGV Gaskets for WRX & STI | 023001
Video description
Improve airflow and optimize your intake system with the GrimmSpeed Enlarged Bore Intake Manifold to TGV Gaskets. Unlike the restrictive factory gaskets, these enlarged bore gaskets are designed to closely match the diameter of the OEM TGV (Tumble Generator Valve), making them ideal for ported intake manifolds and performance engine builds.
By eliminating the bottleneck created by the smaller OEM gasket opening, these gaskets help create a smoother airflow transition from the intake manifold into the TGVs, improving airflow quality just before air enters the engine.
