Oil filters absorb a lot of heat from high-performance engines. They nestle snugly against the oil pan and engine. DEI's Oil Filter Heat Shield effectively blocks radiant heat that can change the viscosity of the oil or potentially cause thermal degradation that causes the oil additives to degrade, dissipate and wear out quickly. Oil cover filters are easy to install due to their self-adhesive backing. They block heat and lower the oil temperature. Universal trim to adjust size works on all oil filters.
