Part Description
K&N, RK-series Twin Cam oval air cleaner assy. Std width
Standard width. K&N realized a +7 HP increase on the Dyno. The K&N RK-Series air cleaner assemblies are truly stealthy air cleaners since the stock air cleaner cover is re-used. Power increase is realized by replacing the stock filter and backplate. A special K&N powder coated aluminum backplate, with Dyno-tuned velocity stack, is required to house the oversized K&N air cleaner element. Built-in breathers replace the stock external breathers. Careful design made it possible to re-fit the stock air cleaner cover for a stock un-touched look. Includes a complete high flow assembly with backplate-filter combo, mounting hardware and a chromed plastic 'beauty ring' with 'K&N' and 'High Flow' engraved. Includes installation hardware. Note 1: Reuse OEM chrome oval air cleaner cover. Note 2: Will not fit in combination with OEM round air cleaner covers. Note 3: Extra wide element will not fit completely under stock cover. Note 4: Will not fit 99-01 FLT/Touring with Magneti-Marelli fuel injection system. Note 5: See 900336 X-wide kit. Or see 900337 for the extra wide (57mm high instead of 44mm) filter element to convert this 900311 air cleaner assembly, complete with offset spacers, for even more air flow. Note 6: See 900337 for the extra wide filter element only, complete with required hardware, to modify this 900311 air cleaner assembly to the 900336 extra wide version.
