Product Details - 1 Pair of Twin Socks (two filters) CS-901

RamAir sock style air filters, which feature two holes cut out of the foam on the underside of the air filter. The two holes are designed so that you can pull the air filter over the top of the trumpets on the carb or the engine's two air intakes - whichever is necessary. To avoid them slipping down the trumpet we recommend using a cable tie to create a platform. This will prevent slippage as you need to ensure there’s at least 20mm from the inside of the filter to the top of your trumpet/intake.

 These filters are constructed completely of foam which enables them to locate in the most difficult of areas. There is no internal cage structure to the filters so are only rated up to 200BHP anything higher you would need to consider caged versions of these.

The hole spacings are correct for the following: Weber DCOE 40 & 45 and IDF 36, 40, 45 & 48, Dell'Orto DHLA & DRLA carburettors
