Should be a required addition for performance bikes or riders in hot weather!

By   on  Verified Purchaser

High quality piece of kit. The included instructions were adequate but a video would've been more useful. Well packaged and high quality parts. If you live anywhere that gets hot out or you have a bike that is well above stock this is a must-do addition. The way the oil is cooled down AFTER it's been filtered unlike the stock method is worth its weight by itself. The fans are icing on the cake. The LED that I mounted on the controls is great and bright.

First class part. Best price.

Amazing product

By   on  Verified Purchaser

Was skeptical when reading reviews. Then purchased ultracool, it exceeded my expectations. If your thinking about purchasing the ultracool. Stop thinking anymore and just buy it...I'm impressed.

Oil cooler

By   on  Verified Purchaser

After over 1,000 miles in 90 + heat, my 2008 dyna takes the temperature down about 10-20 degrees cooler w/ dip stick temperature gauge.

Questions & Answers

Ask Question

Will this fit my 2007 harley-davidson FLHTCUI

Yes, if you were to choose the 2007 Harley Davidson FLHTCU Ultra Classic Electra Glide oil cooler from our fit guide, you'd receive the correct components to fit your machine. Harley-Davidson actually dropped the I suffix from their fuel-injected bikes for the 2007 model year since everything they built went to a fuel-injected engine. It's for that reason you don't see an I suffix on any HD model in our fit guide for 2007+ machines.

Answer Question

Will it increase oil pressure

No, these oil cooler kits do not replace the oil pump itself, and therefore, do not increase oil pressure. They simply provide a nice radiator through which oil temperatures can be quickly reduced while moving oil through the motor in the usual manner. If you want to increase oil pressure, you'll need something like a Drag Specialties High-Performance High-Volume Oil Pump, Feuling HP+ Oil Pump or S&S Oil Pump, depending on your particular application. Combined with the UltraCool oil cooler, you'd probably have a solid-running and well-lubricated motor under your control.

Will this fit my 2005 Electra Glide Classic injected with engine guards?

Looks like it should not be a problem to mount this kit on your 2005 FLHTC with engine guards. It will be mounting down low under the regulator which should be plenty far out of the way of any engine bars.

By Andy
