It says the "power box" installs to An engine data sensor. Stay away?

 

I would say hp gains for an 03-04 -260 hp for a non rev up 05-06 -280 hp for a rev up -298 hp.

 

What exactly is rev up

 

Simple bolt ons doesn't really get you that much power.. the VQ engine is already pushing a lot of hp in NA form.. if you want real power.. for turbo or supercharger.. if you can't afford it.. then spend the money on something else.. because simple bolt on equipments will give you negligible power.

 

take you money and run...

 

Z-tube, drop in K&N, intake spacer. Lower to desired ride height, pick a nice set of wheels and tint the windows.

Then just enjoy it

 

+1 ^^

 

There is no such thing as chipping these cars. You can reflash or get a stand alone. Plenum spacer and high flow cats/art pipes are the best bang for your buck

 

I have a 2005 and I want to install a cold air intake. What would be the best performance one to get? I also need it be legal to pass California smog check. Suggestions?

 

Welcome, search the forum & read others opinions. Many suggest CAI will hurt performance. I have a stillen CAI with a z tube. it will block out some of the heat that the others may not.

I feel better throttle response and the sound is much better.

One of the forum members had a stillen/z tube combo for a pretty good price.

 

Serious patience required to respond to that one lol^

 

K&n

 

K&N drop in filter is your best option.

 

what is a better intake?: CA, SR,CCA

 

Add rev up back half of air box. Keep everything else stock including filter or go with dry flow. Just my opinion as I don't like oiled filters combined with mass air flow sensors.
