This spin-on engine oil filter removes particulate from the lubricating oil before it reaches the main bearing journals and turbocharger supply. It mounts on the engine block filter head and houses a pleated cellulose media that captures wear debris and combustion byproducts. A clogged filter restricts oil flow, causing the bypass valve to open and send unfiltered oil through the engine, which accelerates bearing and turbo wear. The filter’s thread size and sealing gasket match the original filter head geometry, ensuring the bypass valve seats correctly and no oil leaks past the seal. On installation, lubricate the gasket with clean oil and tighten by hand until the gasket contacts the sealing surface, then give an additional three-quarter turn.
