An in-line after-air filter is disclosed for optimal filtration of a maximum volume of air flowing to the engine. A multiple filter system comprising discrete abutting reticulated foam filter elements of different porosity impregnated with a petroleum-based agent trap air contaminants as the air flows from the primary filter to the engine manifold. An air expansion coupling, flared air inlet port and an air diffuser allow maximum air flow through the filter elements. A retainer plate having numerous six-sided openings allows a maximum volume of air to flow through the outlet port and the air funneler coupling to the engine manifold.
