At Last A Oil Filter That Actually Lowers The Temp Of The Oil
I have tried 3 oil coolers on my 2011 Triglide that were worthless, one with a fan that actually raised the temp 13 degrees. I have a Dakota Digital instrument that is somewhat accurate. In a quest to keep the oil temp under 230, without doing something drastic and ugly I have been looking for the best oil cooler and I think I have found one I am happy with. I have been in touch with Marv at Jagg for several months and waiting for the new 10 row dual pass with a fan. In earlier discussions with Marv I have learned a lot about cooling the oil and how coolers are manufactured. I was so frustrated that he actually was going to purchase one of his competitors units I had removed just to test it. It took 6 weeks but the other manufacturer did gave my money back with the pressure of the retailer helping. The retailer no longer carries that brand after checking my facts on it raising the temp of the oil as he was running one on his trike with out a way to check the actual temperature.
He now has a Jagg 10 row dual pass with fan on his trike also although he has it in a chin spoiler. After testing the Jagg unit, it will hold the oil below 230 at 70 mph highway speeds pulling double on a 100 degree day. Nothing else has come close. The stock unit on the 2011 Triglide would hold around 260 in the same conditions with the mods I have on the trike. That is with Amsoil syn and K & P filter. I think the real trick is in the oil filter adapter which they (JAGG) wants you to use. It runs the oil through the filter first then the oil cooler, Just backwards from Harley and other after market units. This improves the flow greatly and cools the oil just before sending it back. Filtering after the cooler would heat the oil some before sending it back. The trike has Woods 555 cams, directional lifters, Thundermax, Fuelmoto headers ceramic coated, V&H Monster Rounds, Doherty Machine Power Pack ac.
This Jagg unit just out is a quality made unit in the US of A, and looks as good as it works. It was a snap to put on and had quality fasteners with it. Every thing fit as they said, it is not the cheapest but it is the best I have tried and I am impressed with the quality and looks. I feel you get your moneys worth. There is a retailer and sponser on this forum that could atest to this if he wishes to post. Thanks, Jerry
