aFe Power Expands Its Lineup Of Bolt-On Large-Bore Throttle Bodies

Increasing the volume of oxygen entering your engine is one of the primary keys to building more horsepower. Fortunately, helping your motor gulp down more air does not have to involve major mechanical changes or complicated garage work.

At the 2026 SEMA Show, aFe Power highlighted its growing family of aftermarket Large-Bore throttle bodies for performance enthusiasts.

Each unit is machined with a wider bore than the stock throttle body, making it an attractive upgrade that bolts directly onto the engine right out of the box. Owners get a clean airflow boost without changing their factory engine setup.

The best part about stepping up to one of these wider throttle bodies is that the factory engine management system stays completely happy as is.

Stuart Miyagishima from aFe Power notes that the engineering team sized the bore increase just right to give the engine an extra bump in horsepower without altering any of the factory electronics.

Because no tuning is required, the installation is strictly plug-and-play. You just bolt one of the Large-Bore Throttle Bodies into the factory mounting location, plug the wiring connector back in, and take the car out for a quick spin.

Drivers will immediately feel a noticeable difference between the stock unit and the upgraded housing when they step on the gas.

Those seat-of-the-pants improvements are backed up by real numbers on the dyno rollers, where the upgrade can deliver gains of nearly 10 horsepower depending on the specific domestic vehicle application.

After releasing an initial batch of throttle bodies for a few select domestic platforms, aFe Power saw right away how much potential this simple bolt-on product line carried.

Enthusiasts wanted an affordable, no-tune way to free up restricted intake airflow on their daily drivers and weekend toys. That strong reception pushed the company to expand its domestic offerings across a wide variety of Dodge, General Motors (GM), Ford, and Jeep vehicles.

Enthusiasts looking to wake up their ride can check out the full catalog of Large-Bore Throttle Bodies right now on the official aFe Power website and pick out the exact match for their build.
