Edge Products' new Jammer injectors provide ultimate driveability. Aftermarket modifications to your intake system increase fuel demand that often exceeds stock factory injector capabilities. These shortages, if not corrected, can result in fuel starvation and ensure engine damage. To address these shortcomings, Edge Products developed its new gas-engine Jammer injector with a major OEM supplier. Rated from 60 lb/hr at 43.5 psi to 83 lb/hr at 87 psi, the Jammer injector supplies the correct amount of fuel throughout the powerband. Precise pulse-width control (under 2 milliseconds) provides exceptional idle and off-idle performance while minimizing emissions. Typical applications include GM TPI/Gen III/Vortec V8s, turbocharged Buick V6s, Ford 5.0L and modular V8s, as well as Triton truck engines.

With so many performance-enhancing upgrades on the market, it's hard to decide what your car really needs. Sometimes the simplest act, like changing your car's spark plugs, can increase the overall performance of your vehicle. E3 spark plugs with DiamondFire technology are a great new choice in the spark plug market. The unique geometry of the E3 design provides optimized spark paths well into the useful life of the spark plug, having long-term effects on engine performance. E3 spark plugs feature a diamond-shaped electrode with the company's revolutionary Edge-to-Edge design. This design delivers forced edge-to-edge spark discharges, which is proven to be the most efficient and effective way to get a spark to leave a surface.

If the lift that you are currently running on your Jeep isn't enough, or if you are looking for an adjustable extra couple of inches, look no further. The Air-Over-Coil suspension kits from 4WD Products allow you to adjust the ride height and spring rate of your vehicle. This system provides all of the adjustment advantages of air suspension and the reliability of steel springs. Unlike an air-only suspension system, the Air-Over-Coil system is designed with on-road and off-road capability in mind. Progressive spring rate is the key. Because each bag's pressure can be adjusted individually, the vehicle can be fine-tuned front-to-back and side-to-side to compensate for load, off-camber situations, and torque roll associated with common coil suspensions. The retention of the coil springs as the basis for the suspension means that airbag or air system failure will not result in a loss of driveability. The system is not intended as a substitute for a suspension lift; rather, it is an upgrade for a lifted vehicle that has been properly set up to compensate for increased driveline angles, steering geometry, track bar, increased tire size, and so on. The new kits are available for the Jeep Wrangler (TJ), Jeep Wrangler Unlimited (LJ), Jeep Cherokee (XJ) and Jeep Grand Cherokee (ZJ).
