Audi 5-Cylinder Billet Main Caps

You're running huge boost or running serious rpms with a normally aspirated engine. The crank twists under load and tweeks the orignal equipment cast bearing caps. The crank "walks" off center, side thrusts load up and warp the bearings... and all hell breaks loose in your precious bottom end. Invest in sensible insurance and suffer no more! Machined in house from solid billet, this 6-piece main bearing cap set will withstand the rigors of competition. Requires line boring.

Fits: All 5-cylinder Audi Engines
