To make large engines with Super D carbs practical for street riding, an air cleaner is needed that will keep air born contaminants out of the engine but still allow the engine to perform. S&S has had an air cleaner available for Super D carbs for many years, but as the engines get bigger we recognized the need for a better air cleaner. The result is a new air cleaner kit based on the S&S taller high flow filter element. This filter element is approximately 1.25 inch taller than the filter in the previous S&S Super D air cleaner kit. Increased filter area combined with the premium filter media add up to significantly more clean air available to your engine.
The new Super D air cleaner kit consists of a billet backing plate, three steel stand offs, an S&S slotted teardrop Slasher air cleaner cover, an S&S high flow air filter, and all required fasteners.
It should be noted, however, that no carburetor support brackets are included with the kit. Since this air cleaner kit is primarily intended for highly customized performance street bikes, the job of fabricating support brackets is left to the builder. With this in mind the billet backplate does not come with any pre-drilled mounting holes. This allows the builder the flexibility to drill mounting holes in any location required to suit the type of mounting hardware used on a particular bike.
The high flow S&S Super D air cleaner is recommended for any Super D equipped engine where air filtration is required.
