Jeep Engine & Fuel System

Replacing your Jeep's air filter with a drop in high flow aftermarket filter will help improve air flow to your engine resulting in a power and performance increase without hurting the wallet. Plus, these filters can be washed and re-oiled (if needed) so it usually will be the last air filter you ever need. Cold air intakes have the same idea as they use a washable and re-usable filter on one end, but then utilize a tube to directly draw air into the engine for a higher torque and horsepower gain.

Hand-held programmers are another way to easily add power and performance to the vehicle without breaking the bank. Programmers generally plug in directly to the diagnostic port and make a copy of the factory-provided tune - then write a new tune to the factory computer which increases horsepower, adjusts the vehicle's idle, changes shift points while some even can clear diagnostic trouble codes and lock Rubicon lockers in 4-HI. Many are even upgradable when new tuning programs are released.

On the top end, Jeep Supercharger kits have become a popular way to gain over a 40% increase in horsepower and torque from your engine, while providing a sustainable boost with no lag that holds up in just about all conditions such as high altitude, desert, and cold wet climates. These kits also help lift fuel economy 1-4 miles per gallon on average, depending on driving conditions In addition, Supercharger kits are mainly bolt on applications that can be installed in one or two afternoons.

While generating more power is certainly important for most Jeep enthusiasts, keeping the vehicle from overheating while doing so is definitely a must as well. Heavy duty performance radiators can maximize a Jeep's cooling efficiency by up to 20 percent over the stock radiator, reducing heat generated by off-roading or from additional horsepower. Many even are a direct fit, making installation easy with no cutting or modifications needed.

Quadratec also carries a wide variety of replacement, crate engine and fuel system parts such as fuel tanks, pumps, oil pans, belts, cables, gaskets, and hardware for Jeep 4.0L engines, AMC360 & Hemi Conversion kits!
