Jeep Cold Air Intake Kit

2018-2022 Wrangler 3.6 Power Package

FMS Performance air intake systems replaces the restrictive factory air filter and air intake housing on your new Wrangler JL. FMS intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable Power and Acceleration throughout the engine’s RPM range. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hoses. The oversized cone shaped air filter can be used for up to 100,000 Miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points.

Wrangler Throttle Body Spacers

2018-2023 Wrangler 3.6 Power Package

Silver Bullet throttle body spacers create turbulence in the air flow at the point just prior entry into the engine increasing horsepower, torque and improving throttle response and fuel efficiency. Silver Bullet throttle body spacers are constructed out of durable T-6061 billet aluminum and using a unique serrated/helix entry to create turbulence at the manifold while eliminating the annoying whistle found in other helix only throttle spacers.
