Removal of Stock BPV

The COBB Tuning Bypass Valve is meant to be used as a bypass valve.  All the cars this product was designed to work on are MAF sensor vehicles.  Using it as a blowooff valve (e.g. not recirculating the air back into the inlet) on any vehicle is undesirable due to the affect it will have on the car's operation.
