Hi, Long time no post.
After installing Nismo CAI, I found something which is really bothering me.
When go on the highway, my G35 sedan start to shake after 120km/h it feels like a really bumpy road. At first i thought the road had some problem. And i try to figure out this problem and came up with some thoughts:
1. Tire Pressure.
2. Stock Sports suspension
3. The Nismo CAI is shaking
4. Im too sensative (but my friend tell me its bumppy too)

Wellz...Maybe there is some other problem that i cant figure out.
My G Fellowz please help me out.

 

Is your sedan shaking? or is it your hearing something rattling? If its rattling then your CAI is proabbly lose, but if the car is shaking, I seriously doubt it has anything to do with your CAI. Odds are you probably threw a weight on one of your rims, which would cause some vibration in the tires. Wouldnt hurt to have someone rebalance your tires.

Other things it might be is if you have really low profile tires, could be your tires are wearing out and can cause a rough ride.
