BMW General Discussion

Talk about BMWs in general. Post official news, Bangle flames, or anything else related to BMW.
BMW has a newly released tech report re: K&N air filters & cold climate regions. They're not degrading K&N, but are alerting dealers that "using K&N air filters in climates below 40 degress(F) can have adverse effects on starting, driveability and fuel mileage." They seem to imply the volume of cold air/density is affecting factory presets and are advising techs to inform customers to switch to an OEM style filter during winter & cold climates. They also mention that K&N filters DO NOT void factory warranty. Just FYI
Yea,it does make sense, my bud in Atlanta is going to fax me the entire thing to read. He says "it's in typical BMW doctrine style" (long) and they give pages of data showing test results. I guess it also shows that the K&Ns do flow more over the entire range and they acknowledge that. I'll post a copy when I get it. (provided it's not "Bentley" size)

Hmm, sounds like something that applies to me, K&N installed. Dealer hasn't seen it yet... And funny thing is, my mpg has gone down quite a bit. Not that the OBC is truly accurate, but it used to show 27+mpg (at times, 30+), now it bearly hits 25.5mpg. May just need a cleaning.

I keep forgetting that - I have a great memory but it doesn't last long
