The machined B-Series valve cover follows in the footsteps of our Mitsubishi products. It is machined in-house with extreme attention to detail. The whole package with the removable timing cover installed is slightly lighter than stock and sports an oversize oil cap, two baffled -12AN breather ports on the front, and a set of custom o-ringed hardware to fasten everything down. There are three different types of matching plug covers available separately. Anodize is available on a per-order basis.
