Made of high quality material, durable and practical to use.
Designed to plug remaining holes in N47 intake manifold when swirl valve is removed.
Improved design simplifies assembly and better sealing to accommodate engines running at higher boost pressures.
Specifically selected polyurethane rubber O-rings to aviod deterioration due to contact with oil found in the intake manifold.
Installation will need to remove the intake manifold, remove the eddy current baffle and eddy current baffle rod and rod bearing, install the plug where the rod bearing was previously installed, reinstall the manifold without coding.
