One of the most-asked question we get is "How do I get more power from my four-cylinder S-10?" We decided to compile a list of power parts for the anemic four-bangers, instead of telling you "swap in a small-block," which is our most common answer. Most of these parts can be installed with some simple handtools and a little common sense, while others might necessitate some involved tools or some welding skills. All of these parts will in one way or another give more performance, either by creating more ponies or helping you get it to the ground faster. Maybe you shouldn't look at a four-cylinder as a bad thing, but as a blessing in disguise. With gas prices skyrocketing right now, these small motors just take less go-go juice to run even when you put some power-adders on. The money saved at the pump could be used to buy new wheels or that NOS kit. Look, we know you might not be able to blow by your buddy on the track, but you can honk and wave as you pass him at the pump.

The 2.2L Poweraid 1-inch throttle-body spacer features Poweraid's unique, patented helix bore design that spins the incoming air charge as it passes through the throttle-body spacer. This air charge contributes to better atomization of the air/fuel mixture at the combustion chamber. The end result is more part-throttle torque, improved midrange power, and overall combustion efficiency for more mpg. The new Poweraid is an easy bolt-on installation and comes complete with all mounting hardware and easy-to-follow instructions.
