Throttle Body Spacer 12-15 Honda 2.4 Liter

The Throttle Body Spacer 12-15 Honda 2.4 Liter from AFE POWER is a precision intake manifold component designed to improve airflow dynamics and throttle response on Honda Accord and other 2.4L models built between 2012 and 2015. This aftermarket spacer addresses a fundamental limitation in OEM intake design by increasing the distance between the throttle body and intake manifold, allowing cooler, more laminar air charge to develop before entering the cylinders. Built for enthusiasts and mechanics seeking measurable gains in mid-range torque and driveability without complex tuning or engine modifications.

AFE POWER's engineering leverages CFD-optimized intake tract geometry to promote air separation and velocity control, reducing turbulence that typically restricts flow at the manifold entrance. The spacer is CNC-machined from high-density polyethylene or proprietary composite material, ensuring thermal stability under sustained engine load while remaining lightweight at 1.21 lbs. Its compact 6.7 x 2.2 x 10.7 inch profile fits cleanly between factory throttle body and manifold surfaces, requiring only gasket replacement and four-bolt fastening—no cutting, welding, or machine work necessary. The design maintains OEM vacuum line routing and sensor compatibility, preserving emissions compliance and drivability.

This throttle body spacer is ideal for K24-powered Accords, CR-V models, and TSX variants running the 2.4L engine that respond well to incremental intake improvements. Real-world users report subtle but perceptible throttle snap, improved response to tip-in acceleration, and better engine character during cruising. Installation takes under an hour for mechanically inclined owners using basic hand tools; professional installation is straightforward and low-cost. Compatible exclusively with 2012–2015 Honda 2.4L naturally aspirated models—verify your specific trim and engine code before purchase to ensure fitment.
