Smart Car Piston Dump Valve and Fitting Kit

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

This kit includes everything that you will require to install the atmospheric dump/blow offvalve to your600cc petrol Fortwo’s, all 700cc petrol Fortwo’s, all Roadsters, and the Crossbladeup to the early 2007 model year. Alsoincluded in this kit is a replacement silicone boost hose.

These will not fit the Forfour, the 800cc diesel Fortwo or the new 999cc Fortwo,, including the 999cc Fortwo Brabus.

The valve has been specially designed for this vehicle and uses twin springs and dual pistons to prevent the valve from leaking air into the intake system at idle with a 12mm inlet to ensure a faster air velocity so that it sounds fantastic.
