Process West Front Mount Oil Cooler Subaru Impreza, WRX, STi FMOC EDO Performance is now a proud distributor for Process West! Process West's Subaru Impreza engine oil cooler system is a must for those with highly modified engines or those that put their car on any type of race circuit. Engine oil loses its viscosity rapidly with temperatures above 110 deg C (240 deg F). This complete engine oil cooler system will keep the oil temperatures down along with reducing the load on the factory engine water cooling system. This gives greater reliability in extreme applications and longer engine life for everyday driving. Oil Cooler System Features: Bar and Plate Core Construction Bar and plate core construction is by far the most efficient type of heat exchanger core. It is also the most labor intensive and expensive to produce, but you pay for what you get. Compact, efficient and extremely strong without the industrial look of units our competitors offer. Goodridge Aluminium Fittings Fittings in the system are produced by Goodridge..the world leaders in motorsport plumbing. We have opted for the reliability of using O-ring sealed threads instead of the more traditional BSP/NPT tapered thread. The kit uses AN - 8 fittings and hoses throughout. Oil Delivery Hose and Clamping Oil delivery hoses are Gates Push Loc internally braided high tensile synthetic textile which is flame resistant and rated to 300psi. Hoses are kept in place by this very neat twin clamp block system. Billet Core End Tanks Precision machined from solid billets of 6061-T6 aluminium these end tanks are one piece to ensure no leaks. Oil Filter Adaptor Block The tight confines around the oil filter area of the Subaru EJ series engine meant that a complete custom built "sandwich" adaptor block had to be designed to suit the application. This part is precision CNC machined from a solid billet of 6061-T6 aluminium. A lot of time was spent ensuring the internal passage ways were as large as possible to ensure zero oil pressure drop through the unit. True Performance Revealed...
