Lamspeed Racing -10AN Rocker Cover Press In Breather Fitting - Mitsubishi 4G63 Evo 4-9, designed for factory magnesium rocker covers, these fittings will save time and money. This fitting is to replace the factory PCV hole on the back of the rocker cover.
Magnesium rocker covers cannot be welded and to do them correctly time must be spent to remove the baffle plates, drill and tap the PCV hole on the back of the rocker cover, chemical washed and the baffles to be refitted.
With our -10AN fitting, these are designed and machined with the correct tolerances so that all that needs to be done is the removable of the factory PCV and grommet. The fitting then gets pressed into the rocker cover. From here you can run a -10AN line to a catch can.
