Add throttle body

Product Details

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. 


  • 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


  • 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

    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.)

    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.
