Well, It looks like I'll be running some AAP deals. I normally run AC Delcos or Wix/NGs in my Cobalt and Cavs, so the M1 and K&N are going to be new to these cars. And if these weren't cartridge ones, I would even bother to ask. For those who are running the K&N/M1 cartridges, how do they do for you? I some rumor about start up issues, which made me think....
