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 RS Big Throttle Body Kit includes:

  • Optional: Brand new OEM Ford throttle body
  • Throttle body extension harness
  • 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.

    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.

    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.
