Zipper's Chrome HiFlow Filter Kit, 2008-up Twin Cam - Throttle By Wire EFI

To Make More Power, you must have more airflow! Increasing airflow at the inlet is step one - even for a stock engine. Zipper's MaxFlow and HighFlow air cleaners include high quality 100-percent washable, pleated filter elements made from multiple layers of surgical-quality cotton gauze material that traps the smallest dirt particles while providing dramatic flow increases. USA-made cast backing plates incorporate internal breather passages and are available in three finishes to match your engine and budget (standard silver aluminum cast, texture black or chrome). All accept the standard TC "football" air cleaner cover (not included). These kits are designed to be used on Twin Cam^® engines equipped with the standard Twin Cam^® “football” air cleaner cover, which makes 360º contact between the cover back and the rubber gasket on the filter. Do not install decorative cover inserts (due to increased weight) or use 2006-up CVO Touring model covers that do not make 360º contact between the cover back and the rubber gasket.

Complete HighFlow Air Filter Kits
These kits are similar to the MaxFlow air filter kits except the filter is the standard 2-1/4” deep. This filter kit increases flow without increasing the overall width of the air cleaner for those with leg room concerns. Fits fuel injected and carbureted Twin Cam^® engines equipped with the factory TC88 “football” cover. Available with standard aluminum cast, black or chrome plated backing plate.

HiFlow keeps the outer cover at the same location as stock.
