This special foam is designed and manufactured for use as a high-performance air filter medium. It is ideal for making your own filter assembly, or replacing worn-out foam from an old filter kit.
The Green foam has 65 pores per inch for fine filtration of dust and other particles. It is slightly finer but very similar in flow to the old "Filtron" foam which has been off the market for many years. It is also a great choice for sealing between an air scoop and the carburetor. Glue the ends together using silicone adhesive (not included). 12 inch x 16 inch x 5/8 inch sheet.
Add the Medium and Coarse foam (sold separately) to make your own three-stage air filter!
Red (Medium) Air Filter Foam Sheet, 40 PPI (Part No. 1265-202)
Black (Coarse) Air Filter Foam Sheet, 30 PPI (Part No. 1265-203)
Note: The Medium and Coarse foams are sold in thinner 3/8" thick sheets.
Our Medium Stainless Steel Wire Mesh (Part No. 3641, sold separately) makes a great support screen when making your own filter.
For best dirt-capturing ability, we recommend treating the foam with an oil such as our Rock Oil Eco Foam Air Filter Oil, Part No. 3818-001 (sold separately).
