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.
In order to adjust the spring tension on the COBB Tuning BPV adjust the set screw in the top of the BPV body.
NOTE: Adjusting the spring tension does NOT adjust the amount of boost the BPV will hold. In order to adjust the amount of boost the BPV will hold, a stiffer spring will be needed.
It is recommended that every time you change your oil you inspect your COBB Tuning Bypass Valve to make sure the piston is still moving freely. You can do so by unbolting the BPV from the vehicle mounting flange and pushing on the piston. If you can feel some resistance, it is advised to remove the piston from the body and clean and re-grease the piston, we recommend ARP Ultra-Torque Fastener Assembly Lubricant, P/N 100-991 1, but any moly-based grease will work fine.
