One of the most asked questions we get here 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 to swap in a small-block, which is our most common response. Most of these parts can be installed with some simple handtools and a little common sense. All of these parts will in one way or another give more performance by either 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 sky-rocketing right now, these small motors just take less go-go juice to run, even when you install some of these power mods. The money you save at the pump could be used to buy new wheels or help get you closer to that body drop. 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, which creates a spinning action of 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. For more information, contact: Airaid, (800) 498-6951, www.airaid.com.
