Silver Bullet Throttle Body Spacer 5.7L HEMI

This increased turbulence enhances air pressure in the combustion chamber, which helps improve throttle response and overall engine performance. A key feature of this spacer is its serrated and helix combination design, which not only improves airflow efficiency but also helps reduce the intake whistle noise often associated with single-helix designs. Compatibility is strictly limited to 2003-2008 Dodge trucks equipped with a 5.7L HEMI V8. Crucially, this spacer does NOT fit vehicles with the factory air intake system. It is only compatible with specific aFe Power air intake systems, specifically P/N 53-10013R and 53-10013D. Please check CARB EO D-550-41 for specific 50-state emissions details.
