    Alright so I'm usually a carburetor guy and I'm new to all this efi stuff. I was thinkin about puttin a new air intake system and a throttle body spacer on my 2000 gt. kinda wondering what kind of horsepower gains I would get from these. If you guys know of any other easy performance upgrades (besides the turbo and supercharges) let me know. Thanks guys!!

    dont bother with a spacer, they do nothing, and a open cone filter will net 0 hp gains really. may improve mpg by 1 or 2 mpg if you drive it all nice. and you may, and do mean may, feel throttle response pick up a bit off the line.

    and you'll hear it sucking in air.


    if you had a sc at least you'd hear it whine. but the end results are the same. no real gains.

    There is no chip for our cars. You'll have to get a tuned pcm.
