I cant confirm this, but that's what ellis stated. It's weird because the factory opti doesnt use an o-lite bushing, whereas the summit and accel claim to be.
An accel unit better than the stock one, not from what I've read so far.

I think if you do some searches, you will see that the Gm one seams to be the one on top. But I can't confirm this. Just that I read that the accel is questionable, I donno why tho.
but they do look allot better than the accel POS's, i guess they have allot of problems with the wheel inside not being perfectly rounded
of course, I DONT pressure wash the front of my engine, and mine is sealed.
I found a slight bit of burning after 80k when I took it apart to inspect, cleaned it, and put a bead of silicone over the seal. Looks good for another 50k...
