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.
Two filter depths are offered, standard MaxFlow and HighFlow:
Complete MaxFlow Air Filter Kits
Here’s a nice power increase that’s easy to install and easy on the budget! Our MaxFlow air filter kit is designed to completely replace the stock air cleaner assembly, featuring our Max Flow element. This cleanable/oilable, pleated element is over 2-3/4” deep to really let that engine breathe! Also included is a one-piece cast backing plate with internal crankcase venting and mounting hardware. 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. Bolt it on and feel the difference!
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.
MaxFlow version moves the cover out approximately 3/4" wider due to the extra deep MaxFlow filter element.
HiFlow is recommended for stock engines; the MaxFlow filter should be used on modified engines with high flow exhaust systems for best results. All required mounting hardware and instructions included.
Add one of our optional billet end covers for radical looks and performance!
