Hyper-Pak air cleaner
170 or 225? I assume 225. It's higher and will be closer to the hood. Here is a picture of what the factory sold in the kit. Still looking for part numbers but the air cleaner assembly was 2129992. Not sure if it was engineered for the 225 or 170 but it is the kit part number. The pictured air cleaner is for the 300 long rams and not sure about the base drop but this is what the kit picture shows. On the dyno photos there is a max wedge style air cleaner with a cut on what would have been the battery side. But that is not what the classic kit layout photo shows!
