TurboXS RFL BOV Kit Turbo DSM

Some people get a blow-off valve because they have an speed-density air metering and no longer have the need to have a bypass valve return pipe. Others...just like the attention.

For that last group of you (you know who you are), we present the TurboXS RFL Blow-Off Valve. RFL stands for "Really Loud." This valve uses a special acoustic horn to focus the sound of the blown-off air, and it works. This is the loudest BOV we've ever heard, bar none. (Click the link below to listen.)

Oh, and it's functional, too. Adjustable spring preload (using included washers) means it can hold as much boost as you want, and it can be set tight enough to not suck in air at idle.

Kit includes the valve, adjustable preload washers, a plug to stop up the factory CBV return line, mounting flange, and all the required adapter hardware for your cars.

Available for all turbo DSM's. Specify model.
