K+N Dual Inlet Filter for Norton Commando
Availability: In Stock
K+N Commando Custom Air Filter
Here's the answer to your question: what do I do if my bike doesn't have the stock airbox?
Fits all Commando models (see note below)
You can eliminate the stock airbox/filter and fit some larger main jets for better performance. This is a win/win!
You can clean and re-oil the filter so you only buy it once.
(If you're putting one on a Mark III 1975 bike, you need to make a bracket for the sidecover mount)
