Obviously if a problem develops with the MAF, having a K&N on the engine has a good chance of being a warranty issue.

The MAF sensor issue was a common problem on older model BMW's, not on newer models. Most members of the M5Board are running BMC (that's a C, not a W
) on their M's with no issues. Most of the E60.net members are running K&N's with no problems.
I have never had any issues on all my BMW's for the last 10 years and all had K&N's, except for my M5 which has BMC.
Furthermore, my dealer works on my BMW's with all my aftermarket parts. I've blown countless O2 sensors due to my exhaust system from headers back and they replace them. Clearly, that is not allowed, but they report my car as stock and do the job. I also have my suspension tuned and have blown some lower control arms due to the suspension. Once again, they fixed that with no problem and no questions. It depends on your dealer. The one in NY that I go to is one of the top in the country. they do this for many of their customers. If you're still worried though, K&N makes a dry filter that uses no oil.
