At Jantzer Performance, we specialize in high quality Performance Throttle Bodies.
Since 2000, we have produced and sold thousands of throttle bodies for late model GM cars and trucks including Camaro's, Firebird's, Corvette's, and GTO's. We are currently working on products for Jeep and Dodge Applications as well.
Our Throttle Bodies are the highest flowing, factory ported housings available on the market!
Our throttle bodies are engineered to outflow the competition and have proven over time to be the most reliable unit available. It's easy to port a LS1 Throttle Body, it's hard to port it for maximum performance. There's a very fine line between an exceptional LS1 Ported Throttle Body and one that's a paper weight. This is why many competitors are very conservate on their porting.
