Type RS features side-tank-type-core. Its large capacity tanks, high rigidity and tube type structure which allows more engine oil circulation will provide excellent cooling performance in racetrack driving.
Type RD features drawn-cup-type-core. This type of the core can be manufactured at lower cost, yet it will offer good cooling performance by using offset type inner fins. Type RD is recommended for those who drive their cars mainly on street, but still like to maintain optimum engine oil temperature at low cost.
Both RS and RD type oil cooler kits come with high quality blue hose fittings which have been newly designed for Racing Oil Cooler Kit. Also sandwich type oil block has been specially designed for these oil cooler kits. The oil block part features thermostat function.
Estimate price=$1.5k for RD type and $2.2k for RS type
