In my experience, when these filters are clogged, after driving it for an extended period (I've been to Mike's house, and I would think he lives about 40km from his shop, although I am not exactly sure a hundred percent where his shop is in T.O.) after that much of a drive, I'd expect the fucker would hardly even run, depending on exactly HOW clogged the screens are. The last one I had wouldn't go 6km without going down the shitter for power. I mean, 15mph, MAX, with my foot on the bellhousing.
