Torque Solution Blow Off Valve (BOV) Sound Plate for 2021 Honda Civic

Emissions Warning: This product is not designed for public highway or street use, and is only legal for formally sanctioned race use on a racing vehicle that may never be used on a public highway or street.

This is not a full blow off valve (it is designed for use with your OEM / factory blow off valve). Please note that some applications MAY REQUIRE AN ECU TUNE for proper operation!

With the design of newer turbos, that iconic turbo blow off valve sound has been quieted more and more. With this in mind, Torque Solution created a spacer that bolts on to your Honda Civic's stock (OEM) blow off valve to increase the sound and excitement each time you lift off the throttle (like when changing gears). Each spacer is specifically designed to directly bolt on to the stock valve and release the extra air to atmosphere. This creates the desired "PShht" sound. Made of CNC machined 6061-T6 billet aluminum and anodized for great durability and looks. Updated low profile design on some plates allows for installation in tight spaces. Each BOV sound plate kit will easily install and should not require any additional work.

Key Features:

• Direct fit for each application.
• Anodized in multiple color options.
• Unique "PShht" sound due to speed of air release to the atmosphere.
• Made from CNC machined 6061-T6 billet aluminum.
• V2 version uses an updated low profile design on some models allows for installation in tight spaces.
• Most kits install in as little as 15 minutes.
