Very easy to install, I was afraid I would have to take my throttle body off before putting this on, however you only need to take the four bolts off and slip it behind the throttle body itself VERY EASY. ...

    Good Product

    Very easy installation. If you follow the directions that come with it from Steeda, you should have no problems at all. Not sure about any gains yet; installed with a bbk intake.

    Very easy to install, I was afraid I would have to take my throttle body off before putting this on, however you only need to take the four bolts off and slip it behind the throttle body itself VERY EASY. Love the whistle. I bought this along with a K&N CAI so I can not say the power gains I experienced were from the spacer alone but between the two purchases there has been a VERY noticeable gain. thanks AM!

    Not bad

    The HP isn't too noticeable, however, a small increase of MPG is noted. 2 major things to note about the installation though: 1) Be very careful when attempting to install this without completely removing everything (CAI, TB, and power cables); it's very easy to damage the gasket ring on the plenum when sliding the spacer in. 2) Read the installation instructions that AM has on here... be sure to use the silicone sealant that they recommend otherwise you can risk causing a vacuum leak which WILL throw a check engine light. Otherwise, good product overall.

    better mpg

    Very easy to install. Noticed a smoother idle right away, as well as a 2 mpg gain on the highway. I don't know how much of a power gain, since I already have dual exhaust, cold air intake, and a hypertech tuner. Overall, a good product.

    first impressions

    i just installed it.. very fast shipping!! it arrived on Thursday when I was expecting it on Saturday.At first i was unsure about this product but i thought why not give it a try...the instructions from American muscle say you need a 5/16 socket wrench, its wrong. i had to use a 8mm. I can tell it has a little more push to the engine, i dont notice a whistle, the only whistle i hear is my K&N high performance air filter and then about 3000 rpm the boomtube exhaust is just too loud and covers it up i guess. I did a few runs using 91 gas and wow throttle response is a bit better, the exhaust got more throatier, and the revs go by faster.. i would reccomend this product! I'm getting a C&L intake soon with a sct tuner so this spacer should take advantage of the higher flowing intake.

    It works!

    Doesnt matter what a bunch of forums say about TB spacers, I tried in my S197 V6 and I can see it increased aprox 2 mpg - confirmed with the computer reading, to verify torque/HP I will need a dyno but it feels like it got a little boost. BTW, it might be that it also works in conjunction with my CAI + tune - also from Steeda

    It's decent

    I had to machine this tough little piece of aluminum to fit the 70mm BBK Throttle Body sold off this website. It's originally made to fit only the stock throttle body which to me isn't worth it. It's very expensive an only adds an extra horsepower or 2. If you want to buy this product, do it for the extra mileage you'll get before hitting the pump. My only real complaint other than me having to alter the piece is the high price. Otherwise, it's worth picking up.

    Good Deal

    i was kinda skeptical aout buying this product but im glad i did. there is noticeable differance in throttle response ( not as much of a lagging feel.) it lets off a nice whistle when you get into it. and i did notice a slight increase in mpg... oh and a 5 year old could install this part. its very straight forward.

    This fit my stock 2006 throttle body which was already 70mm, much to my surprise! With this steeda and airaid cai, i`m outta the gate and down the road!! Where I was getting 23 mpg am now getting 26 @ 75mph average! I`m stoked!! 89 octane. Tuner is next!

    Its ok

    Its very easy to install, my dads friend is a mechanic and he did it in probally 10 minutes. You dont need to disconnect your battery or use silicone, you never want to use silicone around the engine, ask anyone who knows what there doing, if you get the torgue rite with your screws you will have a tight seal, as far as performance gains... uhh not really probally 1 - 2 mpg better on the highway, other than that nothing. no whining or anything like some other people have stated, its all in there heads.

    Good Bang For Your Buck

    This by far was the easiest mod that I've done yet. I haven't noticed a huge power gain after installing the Throttle Body Spacer, however the motor does run about 200-300 rpm less on average across all gears. In addition to improved fuel economy the engine recovers from its revs quicker allowing for better throttle response. Overall great product for its price!

    It works

    The difference will be noted on the fuel economy. When install make sure that is rightly centered, if you don't hear the whistle is not centered and is not working in the way that should be.
