So I am going to order up some spark plugs.
I was to use the IK22

But my listings offer a IK22 and a IK22D
Both list Honda but none say Honda Fit.

Anyone have any ideas?

I'm looking at around $9 a plug.

 

If you want to do the cooler plug 91 octane+ mod, It's been brought to the members attention just to buy S2000 spark plugs. That said, im still trying to find out which s2k plugs to get if they are even different the F20C or F22C motors. BTW this mod makes great power/torque through mid-upper rpm.
