Strange sound X5M
I just picked up my X5M this past weekend and noticed a strange sound at WOT, it happens every time i floor it and it kicks into the next gear is that normal?
Edit: I forgot to mention there's a K&N sticker on the engine cowl. I haven't pulled the filters out to confirm if their K&N yet, but would that flutter sound be the intake at WOT? Last edited by Cattivo; 05-18-2015 at 10:22 AM.. |
