Product Description

GReddy built this Circuit Spec kit around the NISMO front bumper found on many R34 GT-Rs, using its existing duct layout to feed the 13-row core with maximum airflow rather than relying on a generic mounting position. The result is a notably stronger cooling effect than GReddy's standard R34 oil cooler kit, aimed at cars seeing serious track time.

As with GReddy's other GT-R relocation kits, moving the oil filter improves clearance for routine maintenance, while the offset-fin core and FRP ducting work together to control oil temps under sustained hard driving. Note this kit's fitment is tied specifically to the NISMO bumper's duct design - confirm your R34 has that bumper before ordering.
