Product Description

Looking to get a little more out of your Focus RS? This kit allows you to run a larger 63mm Ford throttle body commonly used on the 2.3 Ecoboost Mustang, vs the factory 57mm unit found on the Focus ST and RS. Throttle body is optional if you wish to source your own from the 2016-2017 Ecoboost Mustang. 

Benefits:

  • Improved throttle response
  • Increased horsepower and torque
  • Easy factory-like install
  • No tuning required, but recommended
  • 63mm measured opening, 60mm throttle plate

The Damond Motorsports Focus ST Big Throttle Body Kit includes:

  • Optional: Brand new OEM Ford throttle body
  • Throttle body extension harness - which can also be purchased individually here
  • Triple-ply silicone adapter coupler 
  • New OEM Ford gasket
  • 8mm head high grade bolts
  • Stainless T-bolt clamps

Note: 

  • May not fit directly with some silicone charge pipes due to the throttle body being larger 
  • If you are using silicone charge pipes, you may be able to trim them and use a 2.5" metal joiner to adapt the piping to the included coupler
  • If your charge piping is larger than the stock 2.5", please let us know prior to ordering

    Awesome Kit

    Purchased the kit with the throttle body for my 2018 RS. Installation was pretty much straightforward. No fitment issues here. Plus, works with my current Stratified tune. But, I will make adjustments with Stratified to update the tune. Thanks Damond Motorsports for offering this Big Throttle Body Kit.

    BIG THROTTLE BODY KIT.....

    I received n installed the Big Throttle Body today for the Focus ST. n I honestly gotta say that I'm very impressed to say the least. Its was definitely a great buy n I do recommend this item. The install was pretty easy really. The only thing I had to buy is if you have the silicone intercooler piping you'll need to buy a piece of 2 3/4 piping to fit the Throttle body cuppler n the silicone piping together. Other then that it was pretty simple..... I definitely recommend this item...... Thanks Damond MotorSports.

    Improved response & duration

    Installation has resulted in improved throttle response from tip-in and more linear feel/delivery of power throughout the range. The gas pedal now provides confidence inspiring feedback making it easier to modulate. Additionally, despite dipping into the throttle a bit more than usual (because it’s more fun) I’ve seen .4 improvement in MPG! Can’t beat that as a unintended bonus. Below is a comparison between old and new. The installation it’s a bit tedious, but if you’ve had the intake manifold off before, you should have everything 100% done cleaned-up and ready drive in 1hr.

    Big Throttle Body Kit

    This kit makes installing the larger 2.3 tb a breeze. Kit includes good clamps, new gasket, a nice mishimoto coupler, longer bolts, and a perfect extension harness. Well done with the kit guys.

    Coupler issue

    I want to start off by saying you guys have great customer support. Sadly you need to inform you customers that if you have depo, mishimoto or Mountune cold side charge pipes you will run into a issue.

    As you can see, you can not connect silicone to silicone without a adapter. Once u upgrade my cold side piping I will be happy to order a second wiring kit!

    Thank you and your company for making this awesome kit!

    Thank you for your feedback! We'll add some notes for this into our product description.

    Love it

    I love the feeling the big throttle body gives. I autocross my ST and you can really feel the difference. It gives the car the throttle response it should of had from the factory. It has also made me get a little better fuel mileage which is great. The only difficult thing about the throttle body is taking the out one out and putting the new one in but I'm sure if you take the manifold off it makes it a million times easier.

    Great Quality Kit!!!

    This kit is awesome, everything you need is there and the critical part (the wiring harness extension) is of very convincing quality. One thing though: the Mustang’s EcoBoost throttle body (GB8E-9F991-BD) that comes with the kit really is a 60mm throttle, not 63mm. The dimension that counts is the narrower part where the throttle butterfly is, and I measured it myself. So you get a 60mm throttle, not 63, but that does not diminish the quality and value of this kit. The PCM can cope with that throttle without modification, so it’s a great complement to a 63mm/2.5” hard boost pipe kit (I use the ETS hard pipes, which are of equally great quality.)

    Awesome

    I was confused should I buy or not. After think for few days, and research, I decided to give it a try. It take me 2 hours to install it, not that difficult but need to remove intake manifold. Result was amazing. Just like how the review from other peoples. I love it, for sure will introduce it to other focus st friends. And thumbs up for damondmotorsports team, great service, helpful and professional advice.

    Modify throttle body for a Ford focus RS

    Part was fine exactly what they promised fit right in with all the hardware necessary. If I bring this part make sure you have a good tuner that knows what they're doing and be detail oriented I'm requesting when you want it delivered if you're doing overnight delivery.

    Comes with almost everything.

    Install is pretty straightforward, came with everything if you haven’t don’t other upgrades. If you’re running aftermarket FMIC and charge pipes check sizing before you go too far. I had to buy a separate 3” intake coupling because the supplied is 3” to 2.5” and wouldn’t fit leaving me w/o a car or having to uninstall until it arrived.

    Focus RS Big Throttle Body Install

    I purchased the throttle body and the install kit separately, and then combined the install once I was ready to go to work. Removal of original throttle body and adapter is straightforward, however the easiest way to disassemble is to remove the intercooler outlet hose from underneath the car, and not disassemble at the throttle body clamp which is higher up, and not very accessible. There is one oil filter adapter hoses that has to be re-routed between the starter, throttle body, and the oil filter adapter. If the throttle body and adapters are installed together, you can easily attach the throttle assembly including the adapter to the intercooler outlet hose under the car. Use caution when loosening and applying 150 in-lb torque the intake manifold bolts, to ensure not loosening, stripping or cross-threading, and everything will be good. I also updated the PCV system baffle at the same time.
