Product Description

The Boomba Racing blow off valve is a direct replacement for the factory bypass valve on the 2018-2022 Honda Accord 1.5T. It gives the 10th Gen Accord the louder vent-to-atmosphere BOV sound many turbo owners want while replacing the factory plastic-and-rubber valve with a billet aluminum unit.

Inside, the valve uses a brass piston and spring-preload design to release charge pressure when the throttle closes. It works with the stock calibration or an aftermarket tune and is available in natural aluminum, black anodized, blue anodized, and red anodized finishes. This is a full BOV replacement, not a spacer or adapter, so it does not retain the factory recirculating setup.

Official Sound Clip

This official sound clip lets you hear the vent-to-atmosphere release from the Boomba Racing Honda 1.5T blow off valve.

Before You Buy

This is the louder vent-to-atmosphere option. If you prefer a quieter setup that routes discharged air back into the intake, choose a recirculating bypass valve instead. Boomba notes that warning lights can occasionally appear immediately after installation if the wastegate connector was unplugged; verify all electrical connections, then allow a few key cycles for the system to reset.
