05- Chrysler 300C 5.7L TB Spacer

The 05-Chrysler 300C 5.7L TB Spacer from AIRAID INTAKE SYSTEMS is a precision-engineered throttle body spacer designed to enhance intake manifold airflow on Mopar Gen III Hemi engines. Built for operators who demand measurable performance gains from their platform, this one-inch spacer increases the distance between the throttle body and intake manifold, optimizing air velocity and charge distribution. Whether you're running a 2005–2013 Chrysler 300C or compatible Hemi-equipped platform, this throttle body spacer addresses a specific engineering constraint that limits stock intake efficiency.

Machined from aluminum and anodized in tactical red, the 05-Chrysler 300C 5.7L TB Spacer delivers durability and corrosion resistance in demanding underhood environments. The one-inch thickness creates a plenum effect that promotes better fuel atomization and smoother airflow transition into the intake manifold, resulting in improved throttle response and modest power delivery increases. The kit includes gaskets and all necessary hardware for direct bolt-on installation—no modifications to existing manifold geometry required. At 0.69 lbs, the spacer adds negligible weight while the red anodized finish maintains a professional, finished appearance that meets OEM-quality standards.

Operators and enthusiasts running 5.7L Mopar Gen III Hemi powerplants benefit most from this spacer when paired with complementary intake modifications—air filters, tune optimization, or fuel system upgrades. The 05-Chrysler 300C 5.7L TB Spacer is a bolt-on solution requiring no machine work; installation takes approximately 30–45 minutes with basic hand tools. Compatibility is limited to Mopar Gen III Hemi platforms (2005–2013 model years and select later applications), so verify your specific vehicle variant before ordering. The complete gasket and hardware package ensures proper sealing and long-term reliability under sustained load and temperature cycling.
