Hello,
My LS performs just fine, but their is always room for a little improvement. Are their any modifications that will both increase performance and gas milage out their on the market that you know of?

Thanks!

Perhaps a cold-air intake. Have you considered one of those?

I've put a CAI on a few of my cars and didn't really notice any difference in performance. The main thing I liked about the CAI is that it almost sounds like a week supercharger when you give the car gas because of the whistle sound it makes.

I've considered that... I may install one of those sometime soon. I think they are around $150 which isn't to bad at all.

What about that thing they have called the "Tornado" or "Twister" Do any of you think that'll work?

Most people don't think very much of those options, actually. They don't do a whole lot, if anything...

Snake oil.

Slap a cold air intake and maybe a new exhaust and be done with it :)

Thanks for the suggestions everyone, I'll try to figure out something to make it perform a little better and let you all know my decision :)

Don't do it... what sounds to good to be true usually is. No device can bolt on 20-30 HP for just a few bucks.

Were you able to purchase or install anything? If so, what was the outcome and how much did it cost if you don't mind me asking? :)
