He guys I I just installed a K&N cold air intake today. Started up my car and there's a ticking sound coming form somewhere. It didn't start until after the cai was installed. I didn't do anything but disconnect the battery terminals. I have seen other post about the same problem, so my question is ,"Is this normal when installing a k&n cai?"

Not normal. Can you post a video?

I drove my car for a couple of days and I'm thinking the PCM adjust to the Cia. The ticking noise is gone!
