NOS Nitrous Filtered Fitting -04AN to 1/4" NPT

The NOS Filters and Filtered Fittings are constructed from aluminum and feature an aircraft type stainless steel mesh filter element to keep containments from attacking the solenoid and plugging the jets. The Billet In-Line Nitrous Filters features 10 times the filtering area over the filtered fittings for added protection!

Installation Notes: It is an excellent idea to check your filter periodically and clean if necessary. All NOS nitrous system kits include Nitrous and Fuel Filters.
