Hey, can you go look at the back where the oil filter screws on and see if your bung comes out? I'm wondering if the b16 or GSR bung unscrews like the R does.

Background: I am trying to hook a maxspeed oil cooler to a b18c5 but due the fact the USDM R comes with a stock (and cheesy) form of oil cooler, the bung is longer to make room for it. The stock cooler is just a ring that water passes thru from a hose in the back. I would need to remove that stock cooler to put my aftermarket sandwich plate on, but as I said, the R bung is too long.
