Comes equipped with a 1.1 Bar (16 psi) cap for reliable pressure control.
Hose Options
Designed to work perfectly with the OEM hose (will need a slight trim) for the best functionality and fitment.

Customizable Finish
Multiple finish options to help complement the look of your engine bay. The options are as follows

Internal Trans Cooler Option
Our race radiator for the IS300 has an option for an internal trans cooler. This makes our radiator a direct drop in option for automatic vehicles not looking to go to an external trans cooler.
The transmission cooler is 50% larger than the OEM cooler. Further, because of the enhanced efficiency of the PHR Radiator core, you'll be cooling your transmission fluid with even cooler water. Thus you get compound cooling effects resulting in cooler transmission fluid, better reliability and higher performance for your transmission.
