best air filter for EC tune??
as I'm waiting for my E63 tune from EC i'm looking to buy some high flow filters. I've searched here and found that the K&N filters may cause problems with the MAF. What other filters can I use for better breathing for my car. I actually bought AFE dry filters but the guy never sent them so I'm thinking maybe I wasn't supposed to buy them.
