How to Get More Horsepower on Jeep Grand Cherokee

by Nathaniel Miller

The Jeep Grand Cherokee began life as a posh off-road vehicle and has gone through many incarnations throughout the years of its production. Today, the Cherokee is a midsize SUV that is ready for a night out on the town or a cruise to soccer practice. The Grand Cherokee features an aggressive body style with a wide tire stance and minimal aerodynamic amenities. There are many different methods of making more horsepower in your Jeep, such as utilizing high-flow exhaust and air intake. These upgrades are the easiest for a novice mechanic to perform and the most common for an initial increase in horsepower on any Jeep Grand Cherokee.

Step 1

Locate the muffler or mufflers along your exhaust. Use the Sawzall to cut the exhaust piping directly ahead of each muffler.

Step 2

Slide the high-flow muffler or mufflers in place on the tubing. Use a muffler clamp and a socket wrench to clamp it in place.

Step 3

Secure the high-flow mufflers with the muffler strapping so as to not stress the other exhaust connections.

Step 4

Pop the hood and locate the air cleaner box near the front driver's side of the engine compartment. Flip open the four clips securing the lid onto the box. Pull the old air filter out.

Insert the new high-flow air filter into the box and snap the lid closed with all of the clips. Close the hood and take the car for a test drive.

Tip

  • K&N Air filters has numerous air filters that will fit your Jeep's air box. These filters are high flow and reusable as well, increasing horsepower while at the same time reducing land fill waste.
