Inefficient factory blow off valves (BOV) can hinder boost response during shifts and can damage your expensive turbo charger. Many clients simply want the street presence of a loud 'phhsst' when making a high rpm shift. If that sounds like you, we have your needs covered. With exclusive harmonic amplification cutouts, this valve is LOUD! Also, adjustable spring tension helps reduce rough idle and stalling found in other products.
Note color choice of Red or Black during checkout.
