Custom oil filter, oil cooler adapter for all Ecotec style engines (2.0L, 2.2L, 2.4L, L61, LSJ, LE5, LNF). The adapter bolts in place of the factory oil filter cap and is tapped for two -10AN o-ring fittings. It is proudly made here in the USA machined out of 6061-T6 aircraft grade aluminum. This adapter can be used for an oil cooler and remote mounted filter. This will allow you to run a significantly larger filter and/or an oil cooler for demanding applications(off road, closed course racing, etc.).
