Air Filters for Solex Carbs
The RC-0500, RU-0500, RU-0520, and 3840 / 3841 series filters clamp directly on single-barrel VW Solex carburetors and have non-replaceable elements. Do not use K&N Sealing Grease on these filters.
The KN RC-0500, KN RU-0500, and KN RU-0520 are ideal for Formula Vee and dune buggies with unlimited clearance above the engine.
The 3840 and 3841 series are designed for installation in the original VW Beetle. The offset mount allows clerance to the fan housing, and the flat design minimizes interference with the engine deck lid.
The 3816 filter fits the two-barrel Solex 40 P11, as used on Porsche 912 and early aircooled Super Vees.
