Here, we’re going to focus on the first part of that equation: a Stage 1 air cleaner (also known as an air intake). A Stage 1 air cleaner typically is best for an otherwise stock Harley with no internal modifications done to the engine. Once you start modifying your engine in search of maximum power, then moving to higher stage components might be in order – but that’s beyond the scope of this list.

Below, we’ve listed some top air cleaners for Harley-Davidsons. Since there are so many types of Harley engines spanning back through the years, it’s best to take advantage of the model finder in the links below to see if there is something applicable for your bike. The selection below is far from exhaustive, as there are tons of models that aren’t on this list. This is more of a representation of what’s available on the market. From round elements to conical, there are a plethora of different designs to suit nearly everyone’s tastes.
