Making sure your oil is fresh and contaminant free is a must of all engine oils; without this, severe damage can be caused to major components due to excessive friction. An oil filter allows for the continuous filtration within engines to purify and remove dirt and other contaminants. While it is recommended by all automotive professionals that using high quality oils and filters assist with the overall health of your engine; without consistent and frequent replacement of these consumables an engine will deteriorate over time. Wesfil Oil Filters are manufacturers in two different designs; the first being the 'spin on' style oil filter which is conventionally seen in most vehicles and are built to withstand the high oil pressures produced by modern engines. The second being the 'cartridge' type oil filter which is designed to simply fit into a reusable housing which is more commonly seen in newer model vehicles as manufacturers attempt to further reduce waste. Wesfil Oil Filters are designed to meet OEM specifications while providing better flow efficiency, longevity and protection for your engine.
