I've been running the K&N HP1002 on my 2.2 for over a year and it's a daily driver so it's been changed four or five times. I love the filter and the nut on the end is not a problem. Might even come in handy if you get a stuck filter. It is also the same filter that is used on my two toyota trucks so I keep a couple in the garage all the time. My oldest Toyota (250,000 miles) suffered some oil related problems early in it's life so I don't skimp on oil any more.
Only Mobil One and K&N filters. It costs a little more but then again I'm getting tired of pulling the engine and spending two weeks replacing all the shiny parts inside.
