This block goes between the oil filter and the block. Built to the same dimensions as the factory oil cooler. If you need to space your oil thermostat out so the lines clear the block or want to delete your factory oil cooler, this is your toy. You will need the matching o-ring.
If you're installing on an NA6, you'll need a longer oil filter pipe as well.
Included in our NA6 oil thermostat and oil cooler kits.
