hey guys my brother just put on a voland CAI on his 04 f150. hes had it on for a couple weeks and theres a vibration under the hood where its at. weve looked at it mutaple times and its tight and installed correctly.
if you have any ideals as to why this is happening please let me know.
thanks

 

contact volant. not many people on this site use that cai

 

did you guys drop a tool, clip, bolt, or anything that might be bouncin around? maybe look around the area for something that came lose and fell somewhere around the area? good luck
