Well, the title says it all. I'm thinking BECK/ARNLEY 0421902 from RockAuto. They also have a Mahle and a Mann. Mann is a Chinese brand posing as a German, so I'm not considering that. No ideal about Mahle. Or is it worth going high performance like K&N? My impression is that they aren't really good in the long run and I've never taken them seriously for a daily driver interested in reliability and longevity.
