Before I purchased Ultracool I would have to stop for 15 or 20 minutes at a time going into the Daytona Race track for bike week . After I installed this unit this year putted right in and bike never got over 215 degrees even on I-4 after over an hour in stalled traffic . Bike generally runs now 185 to 200 degrees all around riding . This is the extra hot 88 twin cam efi .
