It is an excellent idea to check your nitrous filter periodically and clean if necessary.

The new NOS high pressure Billet Aluminum Filters (#15550 & #15552) feature a precision billet aluminum body and a cleanable stainless steel mesh filter element that has 10 times the filtering area of a standard filter. All NOS nitrous systems include Nitrous and Fuel Filters.
