I had interest in this a long time ago and finally got around to doing it. Brian (Jowett Engineering) verified the fit and I believe he has the aluminum housings available for purchase.
The perforated tube from your composite housing needs to be transferred to the new housing. To do this, just bend the locking tabs so they point at you as you look into the housing. (90 degree angle) Note the position of the locking tab before bending it so you can bend it back to the original position.
After bending the locking tabs, push in on the tube and rotate it 90 degrees. It should now come off in your hand when you release pressure.
Remove the tube from the new housing and transfer the old tube to the new housing. Be sure to bend the locking tabs back into their original position.
Install new filter and "O" rings, then carry on with your oil change as usual.
If you think this is as cool as I did...find Jowett Engineering and send him some rep points for doing the research and verifying fit. Thanks Brian.
Sorry for the fuzzy pic. This is the locking tab that needs to be bent toward you to the 90 degree position. After that, just push in and twist.
