Product Description

The Mishimoto MMRAD-RHD-R33 performance aluminum radiator is designed specifically for the Nissan Skyline R33 equipped with the RB25DET engine and manual transmission. With a thick 3-row core and increased fluid capacity, this radiator delivers up to 30% better cooling efficiency compared to the stock unit. The included 1.3 Bar cap raises the coolant boil point, further protecting your engine under stress.

This radiator is ideal for enthusiasts running modified N/A or turbo setups, daily drivers in hot climates, and track users seeking improved temperature control. Installation is straightforward - no cutting or modifications required. Please note: this unit fits manual-transmission R33 and R34 GTT models only; it does **not** fit GT-R models without modification. For automatic transmissions, consider adding Mishimoto's universal transmission cooler.
