For IS-F owners looking to improve the cooling capacity of their radiator, or those suffering from radiator failure common in higher mileage IS-F's, RR Racing is pleased to introduce our Performance Radiator and transmission cooler kit. Our upgraded transmission cooler is required when replacing the radiator to a Koyo unit due to the lack of the OEM transmission cooler. The results are much improved cooling for your engine and your transmission.
Please note that even if your radiator did not suffer a failure, most likely it is clogged with debris (especially in the back of your radiator). Any ISF can use a new cleaner and larger radiator!
