Wondering if anyone has any experience with both the Jagg and HD Oil coolers. I'm in San Antonio where it was 96 today and was wondering if the 10 row cooler from Jagg realy outperforms the HD unit. Looks like the HD unit has 6 rows but is cheaper $299 vs $225 + $150 for the Jagg cooler and adaptor. Does the auto thermostat on the Jagg make a difference, can you have oil that is to cool in the winter or is the non thermostat adaptor fine? Does the the HD model run the oil throught the filter then cooler like the Jagg? What is the qaulity of the HD unit? I know the jagg's are top notch, use to run Setrab on our late model 1/4 mile cars and never had an issue under lots of abuse. Thanks for all the great knowledge on the site.
