Intake Manifold Coolant Adapter Plate for Honda and Acura K20/K24 Series High Strength

Main description

Engineered for reliable Honda/Acura K-series swaps, the Honda Acura K Series Intake Manifold Coolant Adapter Plate delivers a rugged, high-strength interface between the K20/K24 head and the coolant system. Constructed from a durable ABS + metal blend, this adapter resists rust and wear, ensuring long-lasting performance in demanding engine bays. It features a 1/8 NPT port to replace the coolant temperature sensor and provides a simple, clean path for temperature sensing in K-series builds. The adapter is compatible with all K24 heads, including K24Z (R40) variants, and can be mounted using either a spring-loaded plate for constant pressure or by tapping the head for a secure, tight seal. Designed to accommodate the K20-type cap on K24 heads, this plate removes compatibility headaches and helps maintain accurate cooling readings during intense driving, track days, or daily use.

Benefits & Tips

• 2-in-1 installation approach: choose the spring-loaded plate for consistent pressure or drill-and-tap the head for a solid, permanent fit—both options deliver a reliable seal.
• 1/8 NPT sensor port enables straightforward coolant temperature sensing, simplifying sensor placement without sacrificing clearance or flow.
• Durable, corrosion-resistant construction keeps the coolant path clear and functional under high-heat conditions typical of K-series swaps.
