What will I get out my car if I modify my Air induction system?

I have a 2004 Chevy Impala with an LA1 3400 V6 and I want to change my existing factory air box into a K&N Cold air induction system. What will benefit my car if I do that? Will I hear a loud scream when accelerate?

1. You'll hear the noise of the air being sucked into the intake. You may get a little more power out of it. I'm not so sure that you'll be able to notice any performance difference but you'll hear the noise so that is something. good luck.
2. always remember, the more air and and pushed air . will improve your h/p and save on gas. lots of things you can do, ,check out shops on the net for free advice,
3. yh...im with these lot...it will increase the efficiency of your engine to draw in cold air and by choosing a K&N air induction kit u will gt better results throttle response may increase but to see a noticible difference save up some oney and buy a Garret Hybrid Turbo...u will c y the air induction kit is so vital...
4. horsepower should raise 10-15% as far as the screem goes hold your hand over her mouth that should fix it
5. hmm...i have no clue....i don't know $hit about cars...but my guess is that it will make a loud noise
6. I have a 2002 Impala with the 3400 V6 and made a custom CAI with a K&N filter. Here's the thing, there are no ready made kits for the 3400 Impalas. But it's easy to make your own, get some 3" ABS pipe and a K&N filter with a 3.5"-4" opening. You're going to notice a few changes immediately, when going WOT (wide open throttle) the engine is going to be noticeably louder. Secondly, you're going to pick up a few HP, nothing crazy. Another good breathing mod is to get what is called the U-bend delete. If you look at your exhaust you'll see a section that is bent like a U where the downstream (behind the cat) O2 sensor is located. By opening up this section of your exhaust with a "U Bend Delete" kit you'll easily gain 5 HP. If you want to know more about modding your Impala, check out www.naioa.com.
