2nd the response from Sco. I was on a trip to the Black hills blew out the gasket on filter mount had to remove filter mount on the road [real pain in the ***]. I was able to finish my trip with just original oil filter. I called Ultra Cool when i got home [very poor customer service] i guess it is my problem there cooler didnt make it a full year before ending up in box in my garage. WOULDNT RECOMEND!
3rd the response on ultra cool my adaptor in leaking now after 1 year. I will try to seal the gaskets this season, but if it continues to leak again I'll find something else too.
I have the cooler from the MoCo, motor is 95" since new, oil cooler installed her second season due to high temps, much higher then I had on my Evo. No issues and it has been hanging on down there since 2006. Good luck.
