HKS 17-19 Honda L15C & L15B Super SSQV4 BOV Kit w/o Recirculation Tube

If you're looking to get a more aggressive sound from your turbocharged 2017-2019 Honda Civic with the L15C or L15B engine, this HKS Super SSQV4 Blow Off Valve (BOV) kit is a popular choice. This kit replaces the factory bypass valve with a vent-to-atmosphere unit, which is what gives you that distinctive 'psshh' sound when you lift off the throttle. It's designed to help your turbocharger spool up faster by releasing excess boost pressure more efficiently than the stock valve.

The Super SSQV4 itself is a well-built unit known for its reliability and performance. It features a unique diaphragm and seal design that helps prevent leaks, even under high boost conditions. This particular kit is designed for a direct fit on the specified Honda Civic models and includes the necessary components for installation, though it does not include a recirculation tube, meaning all the air is vented to the atmosphere. This setup is favored by many for the audible feedback it provides, and it's a common modification for enthusiasts looking to personalize their turbocharged vehicle's sound profile.

Keep in mind that this kit is not CARB approved and cannot be shipped to California. For models that allow it, this BOV can offer a noticeable change in the sound of your turbocharger and potentially a slight improvement in how quickly the turbo responds after you let off the gas.
