Now I know OEM is best on certain things like injector seals and sensors. I am wondering what some people think about aftermarket oil coolers. I used a swag performance oil cooler and have no problems but was wondering what y'all think about the cheaper alternative vs OEM high priced but proven good parts. What are the bad OEM parts that need to be updated (the high pressure oil lines) and the parts that need to stay stock (injector seal). Also thoughts on the ts 6 position for towing.
