Katech Releases 103MM Throttle Body for LT1 and LT4 Engines

Increased blade diameter and inside CNC profile allow for greater airflow without sacrificing drivability

Katech Inc., a world leader in performance engines, today announced a new 103MM Throttle Body for GM LT1 and LT4 engines.

“We knew early on that we would need a larger throttle body to push the LT1 and LT4 engines beyond their factory performance levels,” said Jason Harding, Director of Aftermarket Operations for Katech. “The increased blade diameter and the inside CNC profile allow for greater airflow without sacrificing drivability. Katech’s billet aluminum design is another highly engineered component that serves to optimize vehicle performance.”

On the LT1, an MSD intake manifold is required to accommodate the larger diameter. In the LT4 application, a CNC-ported supercharger snout is required. For both applications, the engine will also require a larger intake coupler. All additional components are available through Katech.

The new 103mm throttle body is designed for the following vehicles:

  • 2014-current Corvette Stingray
  • 2015-current Corvette Z06
  • 2016-current Corvette Grand Sport
  • 2016-current Camaro SS
  • 2017-current Camaro ZL1
  • 2016-current Cadillac CTS-V

The 103mm throttle body is available exclusively through katechengines.com for $649.99.
