PRODUCT DETAILS
Honda K20A2 / K20Z1 / K20Z3 Intake Valve – 14711-PRB-A01
This single Honda K20 intake valve is a genuine OEM replacement for K20A2, K20Z1, and K20Z3 heads used in the 2002–2006 Acura RSX Type S and 2006–2011 Honda Civic Si. If you’re chasing low compression, random misfires, or the telltale signs of a burnt valve, this lets you replace just the bad intake valve instead of buying a full set. It’s a smart move for K20 head valve replacement on high-mileage engines, refresh builds, or budget-minded repairs where only one or two valves are out of spec.
Each K20A2, K20Z1, K20Z3 intake valve matches factory dimensions and materials, so you get proper airflow, sealing, and long-term reliability back in your K-series head. Whether you’re keeping your daily Acura RSX Type S alive or freshening a hard-used Honda Civic Si track car, this Acura RSX Type S valve / Honda Civic Si valve drops in like the original.
If you are looking to replace the whole set of intake valves, you will need to purchase eight (8) valves.
