S&S Cycle Air Cleaners: Stealth Kits, Plates and Filters

Best for
2008-2010 Road King owners wanting compact style

The S&S Cycle Chrome Mini Teardrop Stealth kit, part 170-0437, shrinks the classic Teardrop cover to 85 percent of its original size and lays it over the S&S Stealth air cleaner system. The listing says machined openings around the rim add style and extra airflow, and a built-in stinger cone guides air smoothly into the carburetor or EFI throttle body to reduce turbulence and increase flow.

This suits the rider who wants the Teardrop look without the bulk of the full-size cover, and who wants a complete kit: the description says kits include the backing plate, filter and hardware. The listed fitment starts with the 2008-2010 FLHR Road King and 2008-2010 FLHRI, plus the 2008-2009 FLHT Electra Glide Standard, and the description is cut off after that, so confirm your exact model before ordering. One oddity: the description says both “Made in the U.S.A.” and “Imported,” so the listing does not settle country of origin. It also mentions chrome or gloss black finishes, while this listing title specifies chrome.

• Mini Teardrop cover at 85 percent of original size
• Machined rim openings for style and extra airflow
• Built-in stinger cone for smoother intake flow
• Kit includes backing plate, filter and hardware

Best for
Twin Cam riders wanting a Stealth kit

The S&S Cycle 170-0300B Stealth Air Cleaner kit is listed as a vehicle-specific, performance-grade part with a conical shape. The model number field reads “01-17 Twin Cam,” which points toward Twin Cam bikes from that era, but the listing does not publish a full fitment table, cover style or list of included parts.

That makes this the pick for a Twin Cam owner who already knows 170-0300B is the part number they need, for example from an S&S catalog or a shop recommendation. If you are shopping on looks and want the included-parts list spelled out, the Mini Teardrop listing above gives much more detail. Before buying, check the part number against your bike’s year and fuel system, since the listing does not specify carb versus EFI compatibility.

The S&S Cycle Air Cleaner Back Plate, part 17-0336, is a replacement-grade plate listed for 1993-99 Harley-Davidson Big Twin and 1991-2003 XL models. It weighs 12 ounces according to the listing.

This is a part for riders rebuilding or repairing an existing intake on those older bikes, not a complete air cleaner. The listing does not say whether breather provisions, gaskets or bolts are included, so plan on sourcing hardware and a filter separately if yours are worn. If you want a full new assembly on a newer bike, one of the Stealth kits is the better fit.

Replacing lost Super E/G mounting bolts

Best for
Super E or G carb owners

The S&,S Cycle Air Cleaner for S&S Super E/G, part 17-0400, is a replacement part tied to S&S Super E and Super G carburetors. Beyond that, the listing is very sparse: it does not specify whether this is a complete air cleaner assembly, a cover, or a backing plate, and it gives no dimensions, finish or included components.

It suits a Super E or G owner who has confirmed 17-0400 is the correct part. If you are unsure, compare it with the mounting hardware and replacement filter below, which serve the same carburetors but only cover part of the job. Treat this listing as a part-number match rather than something to buy on description alone.

The S&,S Cycle Air Cleaner Mounting Hardware package, part 17-0437, is the Super E and G hardware kit, listed as made in the USA and weighing 7.2 ounces. Do not confuse it with the Mini Teardrop kit’s 170-0437 part number; the numbers look alike but refer to different items.

This is for the rider whose air cleaner itself is fine but whose bolts are lost, stripped or corroded. The listing does not enumerate the individual pieces in the package. It will not help on a Twin Cam Stealth setup, since it is listed specifically for Super E and G air cleaners.

Budget filter swap on S&S Teardrop kits

The 106-4722 Air Filter Compatible with Teardrop kits is made by TONNISI, not S&S Cycle. It is sold as a replacement for the S&S 106-4722 element and cross-references several other part numbers, and it is listed for S&S Super E/G carbs, single-bore EFI and CV carb setups. It includes one filter and lists a one-year warranty.

This suits a rider on a budget who needs to replace a dirty or damaged Teardrop element and is comfortable with an aftermarket part. The listing’s description is confusing: it says the product “is made of soft rubber,” which does not describe a pleated filter element, so the actual media is not clearly specified. If you want a genuine S&S element, note that none is included in this roundup other than the filter bundled in the Mini Teardrop kit.

• Replaces S&S 106-4722 and several cross-referenced numbers
• Listed for Super E/G carbs, single-bore EFI and CV carb
• One filter per pack, one-year warranty listed
