Flat top polished alloy rocker cover with chrome cap fits nearly all A-Series models (beware if you have highlift Rocker). Bolting on an aluminium valve cover is the age-old way to dress up the engine compartment on any car. This finned aluminium valve cover utilises the classic flat-top "Westlake" design. Polished aluminium valve covers look great, but did you also know that they will also aid cooling the engine oil as it splashes the inside and dampen engine noise.
