Honda K20 Exhaust Valve Spring – 14762-PRB-A02
This OEM Honda K20 exhaust valve spring (14762-PRB-A02) keeps your exhaust valves where they belong – seated properly and following the cam profile instead of floating at higher RPM. It’s a direct Honda K Series valve spring replacement for K20A2, K20Z1, and K20Z3 exhaust locations and works perfectly when you just need a single exhaust spring replacement instead of a full set.
This 14762-PRB-A02 valve spring fits the 2002–2006 Acura RSX Type S and 2006–2011 Civic Si. It’s sold individually, so you can replace a single tired exhaust valve spring without buying eight. If you want to refresh the full exhaust side, you’ll need 8 of these OEM Honda valve springs.
Running the correct RSX Type S valve spring or Civic Si Honda valve spring on the exhaust side matters. Exhaust and intake springs aren’t the same – rates and installed heights differ – so mixing them up can cause poor sealing or valve float. Sticking with the proper exhaust valve spring 14762-PRB-A02 keeps your K Series timing, lift, and reliability where Honda intended. We use these same OEM Honda K Series valve springs on customer cars when we need a known-good baseline.

Why Replace a Single Exhaust Spring?
If you’ve had a valvetrain issue or you’re tearing down a head and find one weak or out-of-spec spring, a single K Series exhaust spring replacement makes sense. One tired spring can cause misfires, uneven compression, or light valve float long before the rest are done. Swapping just the bad Honda K20 exhaust valve spring lets you fix the problem without paying for parts you don’t need. When you replace Honda exhaust valve spring components with the correct OEM part, you keep your K Series reliable at factory revs and beyond.
