PRODUCT DESCRIPTION
Forge is proud to offer this open-circuit blow-off valve adapter for the Mercedes A180, A250, CLA 250, and GLA 250. The spacers have been developed to produce an exceptional blow-off valve sound on these vehicles, which are known for their quietness. This CNC-machined aluminum spacer gives you the sound you're looking for. When you release the throttle, you'll hear that beautiful and satisfying "pschhhht" that tells everyone your Mercedes is supercharged.
It has been designed to work with the standard solenoid valve and uses high-quality O-rings for a perfect seal. Mercedes has equipped this vehicle with a closed-circuit blow-off valve, which allows the re-injection of compressed air into the intake circuit. The disadvantage of this system is that the re-injected air is hot. By installing a blow-off valve adapter like this, you avoid this problem. This excellent compressed air relief solution includes everything needed for installation. Box contents:
1 FMSPMERC open circuit blow-off valve adapter
3 M6 x 35 Allen screws
1 Forge sticker
