Add Easy Bolt-On Power With aFe Power’s Large-Bore Throttle Bodies

Feeding an engine more oxygen is one of the most reliable ways to unlock extra horsepower. Usually, getting more air into the intake manifold requires big mechanical changes that turn a quick weekend project into a complicated build.

At the 2026 SEMA Show, aFe Power showed off a much simpler solution with its lineup of Large-Bore Throttle Bodies. Designed with a noticeably wider bore than a factory throttle body, each unit lets your engine feast on extra airflow while remaining a true bolt-on upgrade right out of the box.

It is an attractive option for any enthusiast who wants more grunt without tearing deep into the motor.

Plenty of aftermarket induction parts promise easy power but still require a laptop calibration to keep the check engine light off.

According to aFe Power representative Stuart Miyagishima, the whole idea behind these Large-Bore Throttle Bodies is increasing the bore size just enough to generate a solid bump in horsepower without touching any of the vehicle electronics.

Because the airflow increase works within factory parameters, you never have to retune the engine computer. Enthusiasts can simply bolt the new throttle body onto the engine, plug in the factory connector, and go for a drive.

Behind the wheel, drivers immediately notice crisper response compared to the stock unit. That extra performance also shows up clearly when you strap the vehicle down to the rollers. Depending on the specific platform, switching over to an aFe Power unit delivers a gain of nearly 10 horsepower on the dyno.

The company quickly recognized the potential in this product family after launching just a handful of initial part numbers (P/N) for domestic vehicles. Drivers jumped at the chance to pick up real dyno-proven power without paying for custom tuning software or giving up everyday driveability.

Building on that early momentum, aFe Power expanded its domestic catalog to cover popular Dodge, General Motors (GM), Ford, and Jeep applications.

Today, owners across all four major American brands can browse the official company website and grab one of these Large-Bore Throttle Bodies for a quick, hassle-free performance boost that bolts on in just minutes.
