I have an 08 mustang GT around 5000 miles. I put on a K&N air charger. But here is a recent problem. It keeps getting lose at the engine. I keep tightening it, and yesterday I was driving and it fell off as I was on the road. I am not sure how long i was driving like that but I stopped at a light and the car started running ****ty and shut off on me. I understand it shut off because the air sensor wasn’t getting any air so it wasn’t providing enough fuel. My assumption is it couldn’t have been off for more then a few min because I am thinking i would have felt it right away? Also I am worried that I could have screwed something up in the engine? Any input on this situation?

hey i have yet to get an intake yet for my mustang. i had a 98 explorer that i installed a K&N intake on and it did the same thing. i dont know how they come for the mustangs but i had hose clamps with mine to lock around the TB. i went out and got new ones that i could torque down a little more which solved my problem.

 

Get a CAI and tune from Brenspeed. You won't regret it!

I doubt you messed up anything in your engine if it was off for only a few minutes. How did it run after putting it back on?

 

I would agree with the above. I doubt you did anything to the motor. I would go ahead and get some new clamps and torque them down to get it to hold.

 

Others have had similar issues. Tightening too much can also cause problems as it can deform components, depending on the brand of CAI. Be sure the inlet is properly seated at the TB and that the clamp is properly located before securely tightening. Most of the problems that I've seen were related to those items.
