While this unit is a little more expensive than some other units, it's worth it. Quality components and excellent install manual. I took my time and completed the install in about 2 hrs. The manual does need more detail regarding the relocation of the OAT sensor but I figured that one out. I have the Lensport Inlet Duct installed and there is still adequate clearance for airflow to the cooler. I also have the Canton Machine 25-284 oil filter installed and there is still adequate hood clearance after the sandwich plate and adapter is installed. Clearance is very tight between the oil filler cap and the OEM air box. I had to grind off the bump on the side of the filler cap to allow it unscrew without hanging up on the driver's side AN fitting. My Innovate oil temp gauge is running about one segment cooler, so the cooler appears to be working and the extra quart of oil will help as well. Jackson provides a new bracket for the windshield washer filler pipe to relocate it for hose clearance but I found I had to drill a small hold in the plastic bracket on the pipe and tie-wrap it to the a/c hose that's next to the pipe for adequate stability. All in all, worth the money and a clean install.
