Performance Machine’s new Super Gas Merc air cleaner cruises firmly into nostalgia territory, adding some hot rod flair to the styling of PM’s original Super Gas air cleaner. With clean lines and more curves than a pinup, this piece features ribbed concentric circles and the Performance Machine logo machined into the center. Equipped with a K&N air filter, the Merc offers optimal airflow and more horsepower than the stock alternative. This gorgeous air cleaner is CNC-machined from billet aluminum with built-in crank case breathers featuring chrome hardware and is available in chrome, contrast-cut, and the Black Ops finish. $419.95.
