I believe TaylorD has done this. he should pop in here soon enough. I know that he re-used the stock intake tube, and didn't use the new one they supply.

Yes, they do work, but you are keeping the accordian type intake hose. That screws up the air flow into the throttle body (and you will need to retain your intake air sensor). You are really better off getting a tuned-pipe intake. I admit that the Thrasher looks cool with the lexan cover, but your gains will not be as high as with a pipe.

That is great that it works for it.. But the question is, how much modifications are needed to the product in order for it to work? If anyone that has installed this in their 2000+ Bonne, I would love to get some directions on what to do.. Also, does it work good? Anyone notice anything different from the factory box?

Not many modifications are needed, looks like a straight swap, a few members have em. You will feel an increase in power, but not as much as a straight pipe intake.

If you want a Thrasher CAI, make sure you do a supercharger pulley mod as well...then you will really feel an increase in power .

ACtually, there are a few modifications. The PCM sits in the OEM air box, that will need to be relocated. The "relocation kit" you get from Thrasher is garbage. You will need to be creative. Check this out:

This is'nt me, this is my friend Ryan, who has had too much coffee, and too many cigarettes...


PM Me if you want more info..

For just the sound effect alone, do something like this...
