ROUGH COUNTRY 3.6L Throttle Body Spacer Kit | Jeep Wrangler JK JL | Jeep Gladiator JT

The Rough Country Throttle Body Spacer Kit is the perfect upgrade to get more out of the 3.6L Pentastar engine in your Jeep Wrangler JK/JL or Gladiator JT. Designed to create a vortex effect in the intake airflow, it improves the air/fuel mixture and delivers more immediate throttle response.

• Increased torque at low and mid RPM, ideal for off-road and towing.
• Sharper throttle response for daily driving.
• CNC-machined billet aluminum construction.
• Easy bolt-on installation in under 30 minutes.
• Includes gasket and all required hardware.
• No ECU tuning required.

The spacer mounts between the throttle body and intake manifold, generating a turbulent airflow that optimizes combustion. You'll notice improved drivability both in town and on technical trails. A simple, affordable and effective bolt-on upgrade for any Pentastar-powered Jeep owner looking to step up performance without touching the rest of the engine.
