What is the benefit of a recirculating blow-off valve like this one?

A recirculating blow-off valve releases excess boost pressure back into the intake system. This helps prevent compressor surge, keeps the turbo spinning between gear changes, and importantly, maintains the factory air/fuel mixture, avoiding check engine lights or the need for custom tuning.

Does this blow-off valve require any modifications to install?

No, the Turbosmart Kompact Supersonic is designed as a direct replacement for the factory blow-off valve. It fits into the original location and uses the factory plumbing, making installation straightforward without requiring any cutting or welding.

What is the construction of the Kompact Supersonic valve made from?

The body of the Kompact Supersonic valve is constructed from billet aluminum. This material choice makes the valve strong and durable while also keeping its weight down.

Product Details

This is the Turbosmart Kompact Supersonic Blow-Off Valve, specifically made for the 2016 and newer Honda Civic Si and RS models equipped with the 1.5L L15B7 turbo engine. This part replaces your factory blow-off valve to help manage boost pressure more effectively, releasing excess air when you lift off the throttle. It's designed to prevent compressor surge, which can happen when the turbo's airflow is blocked, and helps keep your turbo spinning smoothly between shifts.

The Kompact Supersonic is a well-built unit featuring a unique recirculating design that helps maintain the factory air/fuel mixture, so you don't have to worry about tuning or check engine lights. Its construction uses billet aluminum for a strong and lightweight body, and the internal piston design is known for its quick response and reliability. This valve is a popular choice for Civic Si owners looking for improved boost handling and a more satisfying turbo sound without the drawbacks of a fully venting valve.

Because this valve recirculates boost back into the intake system, it's a direct fit replacement that doesn't require any modifications to your factory plumbing. It's a solid option if you want to upgrade your turbo system's performance and durability.
