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. ...

    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.
