PRODUCT DETAILS
Honda K20/K24 Exhaust Valve – 14721-PRB-A00
This OEM Honda K Series exhaust valve (Honda exhaust valve 14721-PRB-A00) is the direct replacement you want when your stock valve is tired, burnt, or not sealing like it should. It fits Honda K20A2, K20Z1, K20Z3, and K24A2 heads, so it’s a straightforward K20 exhaust valve replacement or K24 exhaust valve replacement for a bunch of popular cars: the 2002–2006 Acura RSX Type S, 2006–2011 Honda Civic Si, 2004–2008 Acura TSX, and 2007–2012 Acura RDX. If you’re chasing low compression, fixing a burnt valve, or freshening a high‑mileage head, this single K Series exhaust valve lets you fix the problem without buying a full set.
Because it’s an OEM Honda exhaust valve, it keeps the factory spec for material, stem diameter, face profile, and heat resistance. That means proper seat contact and reliable sealing under real abuse—track days, long highway pulls, or just daily commutes. It works perfectly as a K20A2 exhaust valve, Honda K20Z1 exhaust valve, Honda K20Z3 exhaust valve, or Honda K24A2 exhaust valve, so whether you’re wrenching on an Acura RSX Type S exhaust valve issue, a Honda Civic Si exhaust valve problem, an Acura TSX exhaust valve refresh, or an Acura RDX exhaust valve repair, you’re covered. It’s sold individually, so you can replace just the valve that’s damaged and keep your rebuild or repair budget under control.
If you are looking to refresh the whole set of exhaust valves, you will need to purchase eight (8) for a complete set.
