Product Details

Part Number: KTD-TB8-RBC
Brand: K-Tuned

The K-Tuned 80mm K-Series Throttle Body features the largest bore of any aftermarket K-Series throttle body on the market. 

  • The throttle body and adapters are all o-ring sealed so there is no need for any gaskets.
  • The TB kit comes with a standard 80mm (3.5") hose barb inlet 
  • The OEM K-Series MAP sensor and IACV are both a direct bolt on, with the ports located on the bottom of the TB, where they are out of view for a cleaner look. 
  • For the TPS sensor, the initial unit comes setup to bolt on the OEM K-Series TPS sensor
  • The throttle cable connection is made using a fully adjustable throttle rotor with 10 settings and a reversible throttle cable bracket. 
  • This bracket allows the user to run the cable on top like the OEM setup or tucked on the bottom. 
  • All K-Tuned Throttle Bodies are constructed with 6061 billet aluminum with a brass throttle blade and a stainless steel, center-less ground, throttle shaft that is leak tested to 90psi. 
  • All TB's come complete with new hardware including: 4 bolts for mounting, plus bolts for the OEM K-Series MAP Sensor, IACV and TPS.
