The WCF oil filter adapter conveniently tilts the oil filter out and down, placing it next to the crankshaft pulley. Most of the 3800's come with the oil filter underneath the front crank pulley, where the engine mount is located on the Fiero, causing the filter to be blocking engine mount installation. This adapter solves these issues. This adapter can be used when installing the 3800 into the Fiero. With this adapter, the short oil filter must be used to clear the sub-frame. This adapter is usable in both automatic and stick shift applications.
