• Designed specifically for Jeep Wrangler 2.5L engines from 1997 to 2006 for perfect fitment

Construction & Design

The AirAid Throttle Body Spacer is machined from high-grade 6061-T6 billet aluminum, a material known for its strength, lightweight properties, and excellent thermal conductivity. This ensures the spacer withstands the rigors of engine heat and vibration while maintaining structural integrity over time. The innovative Helix Bore design creates a controlled spiral airflow, which increases the velocity of the air entering the combustion chamber. This enhanced airflow promotes better mixing of air and fuel, leading to more efficient combustion and improved engine performance.

Performance & Sound

By improving the atomization of the air/fuel mixture, the AirAid Throttle Body Spacer delivers stronger torque at lower RPMs, particularly from 800 to 3,000 rpm. This results in a more responsive throttle and enhanced mid-range power, which is especially beneficial for off-road driving and everyday street use. While the spacer primarily focuses on performance gains, it also contributes to a smoother engine operation without altering the exhaust sound.

Installation & Fitment

Installation of the AirAid Throttle Body Spacer is straightforward and can be completed in under an hour with basic hand tools. The spacer is designed to fit directly between the throttle body and intake manifold of Jeep Wrangler 2.5L engines from 1997 to 2006. No drilling, cutting, or permanent modifications are required, preserving the integrity of your vehicle’s factory components. All necessary gaskets, hardware, and brackets are included to ensure a secure and leak-free installation.
