New to the forum (On to 2nd GP)

Hello, I am new to the forum I recently picked up my 07 Grand Prix GT S/C - I have proceeded to mod my car in the correct order (I hope) I have dropped in a 180* t-stat, colder plugs and 10.5mm wires. I am currently running a HAI (I do not need a lecture on the intake as I know there is a major debate on this subject just looking for help or input) I removed from my 04 GT and now the 07 has the same issue my 04 had. Between 2k- 3.5k RPM (under light load) there is a ticking, knocking annoyance - I wonder if this is the infamous KR which I can actually hear or if its the aluminum intake I am running causing excess air.... I am not sure what it is. The car runs absolutely flawless as does my old GP I just wonder what exactly would cause this ? (obviously it has to be the intake) but why would a simple HAI cause this ? Thanks

I feel like it's just the sound the filter makes. My car does it too and it's an 06 and I just threw a filter on it

If you fear you have KR (more then normal), then you need to buy and aeroforce to scan your car

I will once I get the cash to afford that (aeroforce) I just picked up a zzp 3inch dp so we will see what it does after the installation of that. Maybe its just an annoyance or a result of the cheap intake I mean honestly is KR really even a legible sound ? as in can one literally listen for KR ?

Its annoying ... atleast to me... I get on the throttle a little and I hear a wondrous rattle or tick ..... I wonder if investing in a Wizaired or Custom FWI intake would eliminate it hmmm.

Doesn't bother me enough to spend like 250 bucks lol

Eh, my custom intake makes some tick/knock at 2k through 3k too. Mainly under load, gets quiet under boost or at higher rpm. Just how these engines are noisy. Never bothered me. It's a 04, and did it since I put the intake on, before the engine work and after. I feel this is perfectly normal and shouldn't worry you. If you pay attention, you will notice it mainly only happen when in overdrive, trying to go up a slight hill.

You have to deal with it or stick the airbox back on!

KR Sounds more like popcorn and you can feel a power loss, as in the intake ticking under light load, well you won't feel any power loss and if you monitor, won't see any KR.
