Improved Racing Oil Filter Sandwich Plate with Thermostat

Improved Racing offers oil filter sandwich plates with thermostats in all the popular oil filter thread sizes for easily plumbing an oil cooler to your engine. Their built-in, rebuildable thermostat bypasses the oil cooler until the oil has reached its maximum operating temperature, allowing your engine to warm-up quicker and prevent oil from being over-cooled. They also allow a small percentage of fluid to continually circulate through the cooler, eliminating air pockets and preventing cold fluid from being trapped in the cooler and shocking the system. Improved Racing oil filter sandwich plates with thermostats also feature a filter bung machined from hardened 410 stainless steel for excellent durability. Please verify the fitment for your application when ordering.

Mahle PowerPak Pistons

Mahle PowerPak pistons are forged pistons with steel pins and wire locks. The pistons are hand-deburred and then coated with dry phosphate to protect against ring micro-welding and pin galling during initial startup. For additional performance, Mahle added its proprietary Grafal anti-friction coating to the piston skirts. Part numbers with T on the end have a cutting edge ceramic-based thermic barrier. The barrier is resistant to thermal shock, insulates the piston crown, and reduces heat transfer to increase performance. These replacement pistons are available in a wide variety of size options for fitment with specific engines and pistons.
