One of the most important components of any nitrous system is a good filter. NOS filters feature an aircraft-type reusable stainless steel mesh filter element to keep contaminants from attacking a solenoid and plugging the jets. These new NOS hi-flow billet aluminum filters feature a precision 2024 billet aluminum body and a 140-micron serviceable stainless steel mesh filter element that has 10 times the filtering area of a standard filter. Our filters feature a radius on the outlet fitting to maximize flow and are available in a variety of sizes depending on your needs.

Features:

  • Constructed of 2024 Aluminum for Strength and Durability
  • Anodized Finish for Great Looks
  • 140-micron Filter Element
  • Easy to clean
  • Reusable Stainless Steel Mesh Filter
  • Male AN Fittings on Inlet and Outlet
  • Radius on Outlet Fitting to Maximize Flow
  • Compact Design to Minimize Weight Without Restricting Flow
  • Overall length - -4AN & -6AN Filter 4-1/8” and -8AN Filter 4-3/8”
