IDI Valve Cover with -12 AN Breather Ports

Often times when turbocharging an IDI, it can be difficult to recycle crankcase gasses without using the stock cdr valve, by modifying the valve covers with welded in billet steel -12 an bungs, blow by recirculation is easily done with any quality universal catch can kit, with a much cleaner and leak free connection. These ports can be on both valve covers for two blowby feed ports, as a single feed and a turbo drain for a compound turbo kit, or you can only modify a single valve cover for a single feed. 

Prices are for ONE valve cover, if you want both sides to be modified, select quantity as TWO.
