Your truck or Jeep has hundreds of components, most of which play a vital role in performance. So when it comes to making a top five list of products to upgrade your engine, you’d think it would be a pretty difficult feat to accomplish. Sure, there are tons of things you can upgrade; you can replace the stock intake system and replace it with a cold air intake like AIRAID’s COLD AIR BOX INTAKE SYSTEM or switch out the stock exhaust system for a performance system like aFe’s POWER PACKAGE and feel an immediate increase in horsepower and torque.

Aftermarket retailers like K&N, Borla, Corsa Performance, AEM, AIRAID, Dynomax, Flowmaster, and Magnaflow are all masters at what they do; and what they do, is boost performance. As such, they can all be trusted to increase the output of your vehicle. The question remains however, just which accessories are the best of the best when it comes to improving performance?

5. Programmers: DiabloSport EXTREME Power Puck

Good things really do come in small packages, and that is one thing you’ll find by installing the DiabloSport EXTREME POWER PUCK. This little guy might look puny, but you can’t argue with his output. Adding this power puck under the hood can produce up to 100 extra horsepower and up to 200 pounds of torque. Top that off with the fact that it will increase your mileage efficiency by approximately 1–4 MPG and you just might start spelling performance D-I-A-B-L-O.

Also, they look and sound cool.

3. Throttle Body Spacers

In an engine, air is power. Installing a throttle body spacer is yet another way to harness that power and turn it into additional horsepower and torque. Installing this bad boy creates turbulence in the air drawn in by your vehicle’s air intake system. When this turbulence infused air comes into contact with the fuel, it essentially atomizes the fuel making combustion much more efficient. Check out AIRAID’s POWERAID THROTTLE BODY BOOSTER, and reap the benefits of turbulent air.

2. Air Filter

Air filters. Not a product that you would automatically associate with increased performance but remember — air is power; and the filter represents the first point of contact between your vehicle and air. Performance air filters like K&N’s REPLACEMENT AIR FILTER or AEM’s DRYFLOW AIR FILTER have two major functions when it comes to increasing your vehicle’s performance: increasing air flow and preventing debris from entering your engine. Increased airflow means improved combustion, resulting in better gas mileage and increased horsepower.

1. Air Intake Systems

Whether you choose a cold air intake system or a short ram system to replace your stock air intake system, the result is improved combustion (for a look at the differences between cold air systems and short ram system, read Air Intake Systems: Cold Air vs. Short Ram). Adding a system like AIRAID’s CLASSIC INTAKE SYSTEM can boost acceleration, improve mileage, and increase horsepower. It does this by drawing more air into the combustion chamber improving the efficiency of combustion, and wasting less fuel.
