No more stamped steel breather caps for aluminum valve covers! Complete your engine dress-up look with a breather cap that actually matches your look! These new Slant-Edge aluminum push-in breather caps are available in five different finishes, and with just about every Bowtie emblem configuration imaginable: raised and milled, recessed with inlaid paint, the unique recessed/raised black field, and even no emblem at all.
