Blackboost FTA blow-off adapter, Mercedes-Benz M256 3.0L (GT43, GT53, E53, GLE450..)

Löylyä kiukaalle (water to the sauna stove) as we say in Finnish! With the Blackboost FTA adapter, you can easily add some race-like hissing and rally-style blow-off sounds to your car’s soundscape.

This simple and effective, flow-optimized adapter, machined from aluminum, fits onto your car’s original DV (by-pass) valve housing and improves the valve’s flow by venting some of the excess air directly into the engine bay, accompanied by an aggressive sound.

• No ECU tuning or other modifications required
• No check engine lights
• Easy Plug and Play installation
• Iconic Blackboost Blow-Off sound when letting off the throttle

TIP: For our finnish customers, feel free to inquire for professional installation services at our Vantaa location, ECU Helsinki.
