Pro Circuit - i Boost 2 Throttle Body KitPro Circuit i Boost 2 Throttle Body Kit Included in the kit: Throttle Body Insert (TRIGA TBI) Improves the volumetric efficiency of the engine by applied Pressure Wave Tuning (PWT). Up and down running pressure wave in the intake system is tuned to ensure the positive peak of the pressure wave is there when the intake valve opens. Using the TRIGA tubular insert will slightly reduce the overall flow area, which will allow enhanced speed over the valve

Pro Circuit - i Boost 2 Throttle Body Kit

Included in the kit:
Throttle Body Insert (TRIGA-TBI)

  • Improves the volumetric efficiency of the engine by applied Pressure Wave Tuning (PWT).
  • Up and down running pressure wave in the intake system is tuned to ensure the positive peak of the pressure wave is there when the intake valve opens.
  • Using the TRIGA tubular insert will slightly reduce the overall flow area, which will allow enhanced speed over the valve while timing the pressure waves for low and mid-range power improvements.
  • On the track, using the TRIGA butterfly valve will increase top-end power. The TRIGA tubular insert will utilize some of this extra power and distribute it over the entire rpm range.

TRIGA Butterfly Valves (TRIGA-TBV)

  • The flow-engineered butterfly valves and shaft are CNC precision machined from steel, which allows for less material use and optimal shape.
  • Eliminates high-end flow loss by lowering flow restriction.
  • Throttle control via the butterfly valve is known for its low-flow loss up to 75% of TPS. The high range flow is more restricted because the valve is still horizontally present.
  • The TRIGA butterfly valve reduces the restriction in the throttle body, which decreases the overall pressure drop over the throttle body at full throttle. This results in higher velocity for improved fuel droplet breakup. This also improves the fuel-air mixture while allowing more air mass flow to enter the combustion chamber. More air, more fuel, more power.
  • On the track, using the TRIGA butterfly valve will increase top-end power. The TRIGA tubular insert will utilize some of this extra power and distribute it over the entire rpm range.

Additional Features:

  • 2 installation configurations
  • Option 1 can significantly increase horsepower in low, mid and top range
  • Option 2 can significantly increase horsepower in top range
  • Easy-to-use and install
  • Significant increase in torque and power throughout the power band
  • Throttle body insert improves the volumetric efficiency of the engine
  • Butterfly valve and shaft eliminates high-end flow loss by lowering flow restriction
  • Can be installed and uninstalled without damaging the OEM throttle body
  • Allows for significantly better throttle response
  • No service necessary after installation
  • Can be installed in a stock bike without changing the fuel mapping or tuning

Perfect toy for an active dog!
Color: Large size (7.9")
My dog absolutely loves this ball with handles! It’s quickly become one of his favorite toys, and he gets excited every time we bring it out to play. The vibrant colors are a huge plus—they make it super easy to spot in the grass, which saves a lot of time during outdoor play sessions. The handles are great for interactive play too, especially for tugging and tossing. I’m really impressed with how well it’s holding up. Even with constant pulling, tugging, and rough use, it’s remained durable and hasn’t shown any signs of wearing out. Overall, I’m very happy with this purchase—and if my dog could write reviews, it would definitely get his paw stamp of approval! 🐾

I have an English Springer Spaniel who is 1.5 yrs. She had this torn apart within the first 5 minutes. This is not for strong chewers!

Great idea poor construction
Color: Large size (7.9"), Color: Large size (7.9")
Great for a dog that likes tug and fetch but the seams are not strong so it ripped fast not from tug but my dogs teeth. I sewed it once since we loved playing with it but it didnt last. Other seams opened. The seams opened in the ball part not by the handles. Less seams and stronger ones would make it 5 star. Im trying a different brand.
