The 2009-2013/01 model used the same valve spring retainers on the intake and exhaust side (part number 13209-AC700). The intake and exhaust uses different springs.

Thereafter, I know that they changed the exhaust spring retainers and spring (retainer part number 13209-1KC0A).

Do the later engines use the 13209-1KC0A on the intake too or do they use the 13209-AC700 like the early engines.
