Alternate Replacement filters for the BMW Performance Air Intake

[MrMaico]

Mike Miller says to inspect/clean at 15,000 and replace at 30,000. Same with the cabin air filter.

I usually do air filter every other oil change, or about 15k mi. Gonna pick up some of the cheap perf. replacements linked above.

Well, I just installed the Mann filter for the Performance Intake.

The pleats definitely look thinner and more open than the oem filter. I also had to play with it a little to get it centered so it sealed well as it's slightly smaller.

I initially figured I'd just keep a close eye on my silicates level on my next Blackstone report. Then I thought about sucking crud into my baby's motor and decided that those kind of thoughts would keep me up at night.

I decided that with how anal I am about everything else with this car, I'm just going to pony up and buy the oem filter.

For the once a year that I change it, I'll just spend the $55.

In the meantime, I'll drive with the Mann for a week until the oem one gets here.

After seeing Marc's pics of the Mann he put in his I'd suggest avoiding that brand. Either the OEM one or the Wix/Napa Gold 6301 that I tried are the best bets. Just because a number can be cross referenced doesn't always mean they will be an identical size.

Agreed.

Well, I ran the Mann until the new oem replacement showed up from Tischer.

I can sleep at night now.

I got some from napa and will replace the mann soon.

[kayger12]

Let me know how you like those.

[zhpnsnv]

Just from taking them out of the box and comparing to stock, I like them much more. I can't say if the fit will be perfect, but it will definitely be more snug.

[kayger12]

Sounds good.

If you're happy with it, I may go that way next year.
