I have a permacool pn 40189 oil cooler that comes with the sandwich adapter, this is brand new in the box. I sold the car it was going to go on and my truck already has an oil cooler. $100

Permacool remote filter single kit pn 10695. This relocates your filter to an area that is easier to get to as well as adding volume to your oil supply for cooler temps. This is also brand new and never used or installed. My trucks oil filter is easier to get to than the air filter so it is not needed either. $30
