Manifold Flange for Hond a K24 Motor

The manifold flange for Honda K24 motor is a precision-engineered header component designed for K-series engine builders and performance enthusiasts tackling bolt-on modifications or full exhaust system upgrades. This flanged adapter serves as the critical connection point between your custom header or turbo manifold and the engine's cylinder head, handling high-temperature exhaust flow while maintaining a sealed interface. Whether you're upgrading from a restrictive factory manifold or building a complete performance exhaust system, this component is essential for K24 applications found in Honda Civic Si, CR-V, and Accord platforms.

Manufactured from durable steel, the manifold flange for Honda K24 motor features a 0.5-inch thickness that provides structural rigidity under thermal cycling and exhaust pressure loads. The oval port design—measuring 4.21 by 1.79 inches—matches the K-series head casting and optimizes flow characteristics for both naturally aspirated and forced-induction applications. At just 1.17 lbs, the lightweight construction minimizes rotating mass while the precision-machined port surfaces ensure optimal gasket sealing and eliminate flow turbulence at the manifold junction. This flange is sold individually, allowing you to source multiple units if building a dual-manifold or turbo twin-scroll configuration.

This manifold flange for Honda K24 motor is ideal for DIY tuners, engine builders, and performance shops upgrading K24Z1, K24Z3, and K24A2 variants. Installation requires careful alignment with head studs, quality exhaust gaskets, and proper torque sequencing to prevent leaks—critical steps for maintaining manifold sealing under high exhaust temperatures. Pair this flange with a quality header or turbo manifold kit, and ensure bolt clearance with any engine bay modifications before ordering. Compatibility spans both OEM and aftermarket header systems designed for K-series flanged connections.
