The consensus on here is that there a waste of money and provide no benefits to fuel injected engines. They help carberated.

ordered a 90mm Throttle body . from what I read on another forum it improves drivability and throttle response. It only cost $139 and is a bolt on. a tune helps with it but not necessary. It shouldn't change mileage because the engine still only needs so much air to go a set speed. The only difference will be ill be giving it less throttle to allow the engine breath enough to maintain the speed. http://www.ebay.com/itm/190698569801?it ... 60&vxp=mtr

JCunningham, please keep us updated when you get your new throttle body installed and have had the time and some miles to evaluate it. I am curious to find out what it will actually do to improve performance etc. Thanks!

For 139 bucks that's not a bad minor upgrade, I don't know how much a couple of mm will do though. I'm looking forward to your review.

got the throttle body today and guess what THIS IS NOT A BOLT ON. You can not use the oem air tube. The tube does not have the clearance. You can see were it was hitting the tube

I'm looking forward to your review once you get the intake tube sorted out.

You would think that the manufacturer of the throttle body, or the business that sold it would have stated that it was not compatible with the stock intake tube. I would have been pissed when I tried to install it, and found that it would not work as is.
