This is a genuine replacement type sports cleaner. It is more effective when used in conjunction with the Super Carbon Air Box, which blocks hot air in the engine compartment and greatly improves intake efficiency. By using the Super Carbon Air Box, which has no ribs in its internal structure, in conjunction with the sports cleaner, the intake air flow is more effectively directed to the intake manifold.
It is introduced on Ameblo's "M&M HONDA's Honda Honki."
