Turbo XS 16-19 Honda Civic Sport 1.5L Turbo/17-19 Civic Si 1.5L Turbo Hybrid BOV - Blue

If you're looking to get a more satisfying sound from your turbocharged 2017-2020 Honda Civic Sport or Si, this hybrid blow off valve from Turbo XS is a solid option. It's designed to replace the factory bypass valve, giving you that classic 'pssh' sound when you shift gears. This valve is built to handle the pressures and heat coming off your turbocharger, so you can expect it to hold up well.

What sets this valve apart is its construction. It uses a large 44mm piston and Viton O-rings, which are known for their durability and ability to seal under high pressure and temperature. Being made in the USA, Turbo XS paid attention to the details, like the hybrid slot design and the vent-to-atmosphere port, all contributing to that distinct sound. It's a direct bolt-on replacement, meaning it should install without major modifications.

Keep in mind that this particular valve is not CARB approved, so it cannot be shipped to California. If you're outside of California and want to add a bit more character to your Civic's turbo system, this is a well-built choice.
