Will this work properly with an aftermarket throttle body? I was thinking of getting the BBK 70mm throttle body and I'm not sure if getting this spacer will affect the airflow/performance of the BBK.


  • The Steeda Throttle Body Spacer is designed for use with the OEM throttle body, and would present a flow restriction with larger aftermarket throttle bodies.

Because it is absolutely necessary to DISCONNECT THE CAR'S BATTERY before beginning the installation? What could happen if I don't disconnect the battery?


  • Disconnecting you car's battery will prevent you from frying your circuitry. It also will allow the computer to properly reset when adding a piece like this throttle body spacer to your vehicle.

    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.

    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.

    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.

    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.

    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

    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 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.

    Interesting gain in mpg

    I have this paired with an airraid cai on my manual v6 and for both them I haven't noticed any real performance gain. If anything noticed more torque below 1.5k rpm. I drive in a rather hilly area and when at freeway speeds and having it in 5th gear I used to have to down shift to fourth to keep from losing any mph even when at full throttle in 5th. But now I can go wot in 5th while going up the hill and the car will increase in speed and it is not bogging any. Also makes accelerating from stops more convenient. I do not need to give any more gas than necessary which means my rpm's do not even get over 1.5k to get going. The biggest plus these two mods have done for me is i have noticed a decent mpg gain. I used to get about 210ish miles per 12.5 gallons of 91 octane. Now im getting 250ish miles per 12.5 gallons of 91 octane. I am not sure if that's a combination of the two but it's good news for me.

    My Mustang

    I have used A.M. multiple times now and i continue to go back due to there fast, free, and easy shipping process, and very helpful customer service via phone and e-mail. i truly can't find anyone better on pricing, product availability, A.M. is #1 for Aftermarket Mustang Parts and they show why. Got this in just a few days by the mail. It was put in on in just about 1hr. and again it not only sounds great, but the performance it also top notch and works really good!

    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!
