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.
