I bought the cheapest one they offered. Notice you can also buy one that is twice as thick with superior cooling ability. THAT is the one I should have bought. The effect of the cooler is provide much better shifting and much more positive engaging. You won't regret buying it, and when the weather turns cold, it has the effect of insulating the radiator and keeping it warm. When it is hot.. it has the effect of increasing radiator area. Go for the bigge!
