Perma-Cool has a universal fit relocation kit that I found for $44.99 on jcwhitney.com. In an older thread I was looking at, it was talking about this kit that includes an oil cooler. It's $115 though. Is the oil cooler really that necessary for normal daily driving? The oil leak I have is coming from the NPT(?) fitting in my stock oil sensor, and I cannot tighten it any more due to the lack of space around the area of the stock oil filter. Only choice I have is to relocate the filter. Will the $45 kit from jcwhitney be enough or do I really need the $115 version?
