IMPORTANT: Honda uses a 2 stage filter, the first stage is called the pre-filter and is a foam case, then inside is a metal frame with screen that serves as the second stage. We are just selling the pre-filter only, our filter needs to be used with the metal frame from the original air filter and that it is a pre-filter only. so when you select the size you need to be aware we are not selling a complete 2 stage filter. when you measure you would measure the clamp point on the metal frame and not the out put flange going to the engine.
