HKS SQV4 Blow Off Valve - S660 JW5 52325-S84-A01 has been given the "T"Installing the SuperSQV4 allows you to clearly hear its distinctive high frequency, crisp operating sound, making it a highly noticeable presence. By replacing the fins with the included SF100, you can enjoy a different sound quality (low frequencies) than with standard fins. Using the SF100 reduces the volume compared to standard fins. It also makes a strong presence in the engine bay and adds a great dress up effect. A return kit is also included.
