Hey just installed the D3 intake on my CTS coupe. This intake is awesome and the sound alone is well worth the money. I have one problem though while revving the car in drive I hear a popping noise it almost sounds like something is hitting something inside the engine. Could it be the cold weather ? It has be 20 degrees where I live. Please help me because I am concerned that this may be causing damage to my engine. Thank you.

Unless you ingested something into the engine, or installed it incorrectly - your intake won't damage your car, especially with the noises you're talking about. Did you secure it down? Your engine may be torquing and the intake hitting the shield.

I bet this is what's happening.

I'm going to see if i can put some rubber stripping on my shield so it doesn't hit so hard.
