Created to be the most reliable blow off valve system available, theType-RS's state-of-the-art design allows for greater performance in a compactsize. Improved response and increased pressure are achieved through carefullyselected spring rates and a large 40mm valve. The real unique feature of theType-RS blow off valve is the CNC machined 8 discharge ports that draw in thesurrounding air to amplify the blow-off sound. The Type-RS is compatible withthe standard GReddy Blow-off Valve flanges. GReddy Type RS features: -High capacity performance, and a compact frame -8 discharge ports that draw in surrounding air and release a unique sound -40mm, hard-anodized valve for increased airflow -High-quality diaphragm and short stroke significantly increase response -Dual spring system promoted response and allows for high boost pressures -Optional discharge adapters for rerouting discharged air -Uses the same two-bolt flanges as the Type-S and Type-R valves**FREE Ground Shipping**
