PRODUCT DETAILS
Honda K Series EGR Port Plate – OEM Exhaust Gas Recirculation Cover (Part #18711-PM1-J00)
This Honda K Series EGR plate (Honda 18711-PM1-J00) is the genuine OEM Honda EGR port cover used to seal the exhaust gas recirculation passage on specific K Series heads. It’s the same Honda EGR replacement part your car left the factory with, not an aftermarket copy. You’ll see this Honda EGR port plate on K20Z3 and K24A8 engines. If you’re doing EGR system work, head service, or dealing with rotted hardware, this is the correct Honda Exhaust Recirculation plate to use. Don't forget the EGR gasket, which can be found here 18715-PB2-000.
Built to Honda’s OEM spec, this Honda K Series EGR part fits cleanly and survives the constant heat cycles without warping. A leaking or missing Honda EGR port cover means exhaust blow-by at the head, lazy throttle response, weird noises in the bay, and sometimes fuel trims that don’t make sense. Swapping in a fresh OEM Honda EGR cover brings the sealing back to stock and avoids the “why won’t this cheap plate seal?” headache.
