aFe Power Brings No-Tune Horsepower With Its Large-Bore Throttle Bodies

Getting more oxygen into the combustion chambers is one of the simplest ways to make extra horsepower. Most enthusiasts want their engine to breathe deeper without tearing into the top end or making major changes to the vehicle.

During the 2026 SEMA Show, aFe Power displayed its lineup of large-bore throttle bodies built to feed hungry engines more air right out of the box.

Every unit features a wider opening than the factory throttle body it replaces, giving modern street cars and trucks an easy path to better airflow and stronger performance with basic hand tools.

What makes this upgrade so appealing to everyday drivers is how simple the installation process stays from start to finish. Many airflow modifications force owners to mess with factory wiring or pay for expensive custom calibration work on a chassis dyno.

Stuart Miyagishima of aFe Power explained that the engineering goal behind these large-bore throttle bodies was to open up the bore diameter just enough to pick up extra power without upsetting the stock electronics. You never have to retune the computer after bolting one onto the intake manifold.

Owners simply unbolt the restrictive factory unit, mount the new housing, plug the factory sensor harness right back in, and hit the road.

That added airflow translates into a noticeable difference in throttle response that drivers can feel from the seat, along with real gains on the rollers. Depending on the specific engine application, slapping one of these units onto a vehicle can deliver nearly 10 extra horsepower on the dyno.

The aftermarket manufacturer quickly realized how much demand existed for a simple, no-tune airflow upgrade after releasing its first few part numbers for domestic vehicles.

Enthusiasts loved getting bolt-on power without the headache of reflashing the factory electronic control module (ECM). Since those early releases, aFe Power has expanded its domestic catalog to cover a wide range of Dodge, General Motors (GM), Ford, and Jeep applications.

Whether you drive a muscle car, a pickup truck, or a weekend trail rig, these large-bore throttle bodies offer a straightforward way to wake up your engine in a single afternoon.
