okat thanks alot guys, i just wanted to make sure cuas ei herd people saying stoires as too them losing mpgs, well now im conviced im gonna go out and buy one, but question is whats the best air intake i can possible get price, brand, cool air intake whatever you guys think is the best one out there, and are throttle body spacers any good too, caus ei was thinkin of buy one too

No, throttle body spacers arent worth it. They dont do much, if anything at all.
If you are looking for a cheap intake, I'd recommend Airaid, it only replaces the airbox with a cone filter, and uses the stock tube. Most others will point you towards either a MAC intake or a K&N. All of these will do you good. It's just a question of how much are you willing to spend.

You will probably LOSE mileage -- most people that measure it do.
Why?
Because more air = more fuel. If you get on the gas at all you'll be using more fuel.
The VERY small increase in efficiency made by less restrictive intake is almost impossible to measure. Virtually all the power gain is made by getting more air to the engine, which in turn makes more fuel go to the engine.
The lessened effort to the engine "pumping" air into the cylinders is very small. This is the only place you could pick up mpg with an intake. There is NO other physical phenomena that will increase your miles per gallon just changing your intake tube, box, and filter.
IF, and this is a big if, you drive EXACTLY like you did before the intake, you will observe no really measurable change in gas mileage.
But most people have a bit more "ooomph" at the top end RPMS and use it, which will cause you to get worse gas mileage.
Anyone who tells you different is trying to sell you something, lol...

i AM trying to sell you something, and even i will say, that ive never seen an intake actually increase fuel mileage. if anything, on a well design intake that actually allows more air, the engine will match the air with more fuel, causing a drop in fuel mileage
if you REALLY want to save mileage, just keep the stock filter clean.
if you still want an intake, any of them are pretty good, i like volant because it uses a closed box around the filter, which helps keep some of the warmer engine air out, and makes the intake a little less noisy. youll find that we have quite a few intakes on our site to check out

There is no change in mpg unless you drive a lot at WOT. The throttle plate is the main restriction in air flow and most driving is done at partial throttle. If you drive most at WOT, then you can expect a slight reduction in gas mileage as John explained. I saw no change what-so-ever in gas mileage on any of the many K&N filters I have installed on various vehicles.
High horse power engines will see a very slight gain in WOT power compared to a slightly more restrictive paper filter.

Here ya go
Fuel mileage is relevant to your driving style, temperature, altitude, terrain etc, etc...
If you get a K&N and drive like a granny, you'll have a slight increase in mpg's. But who's to say you wouldn't get the increase with a stock filter? It's a very debatable topic.
But the thing I like about the K&N, (which will be enhanced with your dual exhaust) is that when you need to stomp on it, you won't have a stock filter clogging things up.
You've already opened up the rear of the motor, so by opening up the front of the motor, you'll be able to take more advantage of that exhaust you've got.
Generally speaking though, efficiency is sacrificed for power.
My $.02, I like my K&N.

K&N sucks, well oiled Gause sucks is what I really mean. I'm not gonna put a filter in that could screw up my MAF sensor !!!!
I went with a microfiber one from Jusnes. Cheaper, less maintenance and same if not better results.
BTW Bob or Kris if you guys catch this thread again, what's the best way to clean my filter and how often should I be doing it? it's probably been almost a year maybe?
