Volume vehicle manufacturers have to produce their cars to very tightly controlled costs. That means many of the parts are perfected for the needs of manufacturing and selling large numbers of cars at the lowest possible price point, so the company can remain price-competitive. That can mean that the stock throttle body on your Dodge Challenger, though fine for regular daily driving, might not be able to keep up with your need for more performance. By installing a high-flow aftermarket throttle body, you open up the intake and fueling, letting your Challenger’s engine management computer increase the amount of gas that gets supplied when you floor the gas pedal. Our Challenger throttle bodies are easy to install because they’re designed as OEM-replacement parts. They bolt in and connect to the stock wiring harness. The high-velocity engineering of aftermarket throttle bodies improve power right through the RPM range and pay their biggest dividends at high revs, where the ability to flow more air and gas truly shines. If you’re modifying other areas of the engine in your Challenger in a bid to boost performance, you’ll be able to maximize your gains with a new throttle body. You’ll see instant improvements, even with no tuning of the engine management computer. If you’re sticking with OE throttle bodies, throttle body spacers can inject an extra dose of performance by altering the path and pattern taken by the air flow. They’re designed to promote swirl, which improves the mixing of the gas and air to produce a better burn in the combustion chamber. By combining upgraded throttle bodies with a cold air intake system and a race-tuned exhaust, you can boost power, responsiveness, and sound throughout the rev range. Boost your Challenger’s stock performance and master the beast with our aftermarket tuning options.
