I need to replace the air filter on my fiance's SL1 but there's a different filter depending on whether it's a single or double OHC and I can't find a way to determine which it is. On top of the engine, it says "EFI/OHC" but that's not neccessarily telling me if it's single or double.

From my limited knowledge, it looks like it's just a single but I can't tell for sure. Any suggestions? I appreciate it.

 

All SL1's/SC1's/SW1's are SOHC.
All SL2's/SC2's/SW2's are DOHC.
