As vehicles age, the radiator can suffer, pits and bends in the core material or even worse cracked plastic end tanks. Once tracked, the end tanks can fatigue even worse as they fight to keep up with the increased demand.
We are pleased to offer a racing Radiator solution from KOYO Racing that resolves the end tank issue with a completely fabricated aluminum version.
For use in the 2008-2011 year IS-F. Other model years will need an upper overflow reservoir from an early model or modify the overflow tube diameter.
We have now added an option to support late model vehicles!
Now available with HPS Silicone Radiator hoses as an add-on kit. Chose from black red and blue colors.
RACING USE ONLY WITHOUT THE FIGS TRANSMISSION COOLER:*Unfortunately, the transmission preheat lines are no longer utilized and the lines that pass through will need to be looped via a 10mm/3/8" union barb, This only impacts the temp ramp rate of transmission temperature on cold starts so vehicles in cold environments should not use this radiator without our transmission cooler.
