What's Included?
These JET Performance Chips for 1992 Jeep Wrangler YJ & Cherokee XJ with 4.0L Engines (Manual or Automatic) brag on their durability and toughness. They feature their Dynamic Spectrum Tuning that provides power gains across the entire power band, not just at full throttle. They have point by point air or fuel ratio, advance ignition and some other tuning tweaks that give more performance gains of up to 25 horsepower. They are very simple to install and covered with a 2 Year Warranty from their manufacturer.
