    D3 intake high rev Popping noise ?

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