This review is for the Skunk2 Alpha cooler on my track only Acura Integra. I drive the car for up to 30 minutes at a time. My Mishimoto radiator was leaking, so I replaced it with a radiator from an auto parts store. My car started to overheat after 15 minutes on track, so I switched to a cheap all-aluminum radiator. This too was overheated. The Skunk2 heatsink is very similar in size and weight to the Mishimoto and comes with a cap. It also cools down. I went from 220F in the winter with cheap radiators to 185F in the summer with Skunk2. I highly recommend this spotlight.
