CSP Rocker Cover Set, Billet Aluminium M18x1.5 Fitting, Type 1 Engines. AC1014505A

The third generation of our bolt-on CSP Products valve covers for Type-1 (not 24.5/36 hp) and WBX engines combine the largest possible space inside for all common rocker arms with the smallest possible outer dimensions and incredibly low weight! They have a heat-dissipating effect and, thanks to their intelligent construction, ensure perfect sealing!

All this is made possible by the manufacturing method. They are not cast, but are each (left an right versions) milled out of billet aluminum using the latest CNC technology! This is the key for rocker covers with the largest possible inner dimensions for all common rocker arm variants with minimal outer dimensions at the same time. In addition to that, organic reinforcement ribs on the inside ensure maximum rigidity.

Really fascinating is the weight of the black hard anodized CSP Products CNC valve covers. At 596 grams, the lightest version weighs just 247 grams more than a standard VW valve cover! Cast aluminum valve covers are in the range of anything over a kilo - the piece!

Like all previous CSP Products rocker covers, they have a reliable seal thanks to the O-ring seals and special shaft screws with additional O-rings. As standard, they have a laser-engraved CSP Products logo and a generously dimensioned, reinforced area (in the direction of travel) for later installation of breather fittings. These are supplied with breather fitting connection threads in M18x1.5 fitting.
