JHM has made a pair of custom adapters that convert the stock oil line fittings to -12AN sizing. This allows you to have the ability to upgrade your RS4 to an aftermarket, upgraded oil cooler core down the road. Here at JHM over the last few years, we have been testing a few different cooler cores on our shop B7-RS4 and others and have found minimal to no gains. This is due to the fact that the factory oil cooler core performs quite well for most weekend road course warriors.

If your stock oil lines wear out, are rubbing through, or have completely failed DON'T GET STUCK IN THE CAGE OF USING ONLY OEM PARTS. Don't buy OEM lines again and restrict yourself to only using OEM parts. Buy theJHM -12AN Conversion Oil Pan Adapters and give yourself the freedom to run the OEM Oil Cooler or upgrade to another cooler down the road!

Includes the following parts:
- 2x JHM Stainless Steel Upper Oil Pan to -12AN Male adapters
- 2x O-Rings for Stainless Steel Upper Oil Pan to -12AN adapters
