Best Bolt-On so far!

This Throttle Body and EGR Spacer gave me more increase in performance than any other bolt on I've had. Most people get new intake manifolds to match 70mm but I highly recommend that you just port match ...

Can I use this with the stock airfilter?


  • The BBK 70mm Throttle Body w/ EGR Spacer will work with the stock air intake.

With throttle body is bigger the70 or the75 and can I bolt it on a stock 5.0


  • Hey Chris, The 75 is larger given that it is 75mm and the other is only 70mm. So the bore is 5 mm bigger. As for a stock 5.0 the 70mm is better for a stock application, the 75 is more for force inducted motors (i.e. superchargers and turbochargers)

I have 1987 LX 5.0 hatchback and 1991 GT convertible. Both are stock* - 87 has speed density, 91 has maf. Will BBK 70 mm throttle body w/EGR spacer be compatible and beneficial with otherwise stock engines*? Any other cost effective improvements? *stock EXCEPT Flowmaster mufflers, K&N filters, 3.55 gears on 87,


  • Yes the BBK 70mm Throttle body and EGR spacer will give you performance gains on a mostly stock car.

    Good additional performance upgrade

    The good part: the difference in the way it sounds and performs is night and day over the stock throttle body and egr spacer but, Now the bad part: i could never get it to idle correctly. come to find out when i took the BBK TB off anitfreeze was leaking into the TB and being suck into the intake. I have tried 3 times to try and get the egr spacer to seal up with the throttle body no luck. No problem with the stock unit which is what is on the car now. If i wasnt having a problem with it leaking I would have given it a 5 star. will try again in spring

    More Power

    The throttle body was very easy to put on once we got the old one off! Twenty some years of rust and corrosion made it very difficult and time consuming to get the old one off. Once the BBK was in place, the only other issue was the grommet on the TV line. The new one did not fit the old line connection. We tried drilling the grommet out, but ended up popping the new grommet out and putting the old one in its place. So far so good! The throttle response is great, much more giddy up in her now!

    Can't Beat It!

    Very easy to install after getting the old rusty throttle body off the intake (use plenty of liquid wrench or other penetrant!). The throttle response and feel is amazing compared to the stock throttle body...you really know when you are giving the car gas. Car seems to run much better overall (take off, shifting, etc)! Good upgrade for a near stock engine! Thanks again AM for the quick shipping and great product!

    Port Matching

    To make ANY larger TB work at its best, you need to port match (use a die grinder and make the ports equal size, even tapering if you must) the intake to the TB, otherwise you will create turbulence and you won't get the most out of it.

    Paired this with a 70mm Mass Air, 70mm EGR spacer, and a Typhoon Intake with a 70mm opening. Sounds great when punching the gas. Throttle response also feels much better. Over all a great product.

    Great Throttle Response

    I bought this not knowing what to expect performance wise after installing it...as a result of hearing mixed opinions. However, after I installed it, the throttle response really is greatly improved, seems like the gas pedal is more "sensitive" and when you want the car to go, it really goes, and much more quickly than the stock throttle body allowed. I can hear a slight whistling noise when first applying the throttle due to not port matching, but nothing my exhaust can't drown out. ;) Overall great product, and great price for what you are getting. Getting the old throttle body off was a little rough and took some time, but the new one fit like a glove.

    BBK throttle body

    Performance is much better than stock throttle body, be sure to reset your tps sensor voltage. Also, If you have an automatic the bushing on the linkage that came from BBK is not the right size as it is too small for the tv cable to snap into. Ditch that bushing and go with an oem one an you will be good to go. Other than that it is a nice performance piece, go with it.
