Katech – 103MM Throttle Body for GEN 5 LT1/ LT4/LT5 Engines (KAT-A6885)

 

The Katech LT1/LT4/LT5 103MM Anodized Throttle Body is engineered for serious performance enthusiasts. Precision-machined from high-quality billet aluminum, this throttle body delivers maximum airflow, resulting in improved throttle response and increased horsepower.

 

At 103mm in diameter, it’s significantly larger than the stock throttle body found on factory LT engines, allowing for greater airflow and enhanced performance. Its 5-axis CNC-milled inlet ensures smooth airflow with minimal turbulence, while the anodized finish provides corrosion resistance and a sleek look.
