What is the best oil cooler ? I have been looking at one I think its called ultra cool it has a fan to help cool the oil.But I don't know if they work well. I have a 09 ultra that I put a 103 kit on and it runs hot, so I need a oil cooler.

 

I like the offering by JAGG i think at one time they supplied for HD as well.
JAGG is USA made if that matters.
I ran one on my old bike and it worked well.

 

The ultra cooler is what I put as I wanted fans & like the stainless lines with the good ends. I gained 4psi even though it has not got hot yet. Had to make a cover for when it's under 50°f it stays cooler even with the cover. Best mod I've done. Just wired up the fans today so bring on the heat.

 

I just checked out the Jagg cooler with the fan. Wow it was $550 and they use rubber hose with hose clamps. So I like the Ultra cool better, braided lines and its like $ 400. So I guess I will order one.They are made in Hollister Calif.

 

I'm happy with the Jagg with fan. I added the optional ss braided lines. Wired the fan to the aux switch.

 

You might want to see if you can get extra gaskets to go in the adapter for the ultra cool reefer. Mine started leaking on me this weekend out of town. No choice but to remove it. More than likely will not go back on the bike. Good unit just can't trust it.

 

I believe the entire setup is made in China. They are based in Hollister.

 

According to their literature there is a thermostat type of device so covering it is a waste.

 

It just turns on fans

 

Good to know ! Thanks. Literature is rather unclear to my dumb ***.
