Tinny sound coming from CAI at higher rpms... - Honda Prelude Forum

I just took my car out for a while to strech its legs and noticed that some of the time there was a tinny metallic sound coming from the CAI at high rpms (6+). I noticed that there is a little play in the movement of the CAI against the whole that was cut for it the fenderwell. Has anybody noticed this before? I assume that at high rpms it vibrates a little and rubs against the metal. Is there a way to line that hole with rubber so that the CAI can't move around?

Don't they usually come with a piece of metal to put on it to connect to the frame of your car so that it doesn't move? My friend has one.

thats strange cause i was gonna post something about this happening to my car that has a completly stock engine, but this is only noticable on my car at 6000+ rpms and is occasional.I maybe thought i need a valve adjustment.

yah it's probably becos your CAI tubing was hitting the enlarged metal hole.
used to have that problem...then i used Sponge+WD40 and it worked hehe

vaccum hose will work too.

One, forgive me for my ignorance, but how did a sponge and WD-40 help?

insert sponge in where ever the CAI tubing contacts the metals that the CAI runs through, then spray WD40 on the sponge in case friction does occure
