Okay! I was scheduled next Friday to fix a broken window switch. However, a buddy of mine brought up some concern regarding to the K&N FIPK kit that I've installed ten days ago. Since I already had some problems with this vehicle. He thought I better of remove the K&N and reinstall the original air box before heading down to dealer. You never know if this time they noticed the K&N on my engine, and later if I have any problem with the engine then they'll use it as an excuse to void the warranty. This sounds very much as a precaution, but I think that better of listen to him. I just hate to spend hours to get it remove. What do you guys think? Anybody has a bad experience with a similar issue? BTW, the K&N fipk sounds great, and is a bit too loud for my taste in the late night driving. I doens't help much in gas mileage. I'm thinking of remove it tomorrow. What would you do? Thanks
