West Coast Fiero

High Performance Intake Manifold



This manifold replaces the top half of the Fiero intake manifold, giving you an effective increase of 64% in the intake air flow and efficiency for highly modified V6 and 3.4 engines. Only slight modifications to electrical are required to accomplish this install. Stock throttle cable and cruise cable are used for this installation. Fuel enrichment via computer chip or West Coast Fiero piggy-back computer will be required. Zero two (02) gauge is highly recommended for tuning fuel delivery. Reverting back to stock is as easy as replacing the old top half of your manifold. 

Unit comes shipped in raw aluminum ready for paint or polishing.
