Vented Performance Dipstick / 99-05 Dyna

The Feuling Vented Dipstick is designed to reduce excessive crankcase pressure in Harley-Davidson Dyna models by utilizing a built-in PCV-style breather system. This innovative design helps improve engine performance, reduce oil blowby, and maintain proper oil levels, making it an essential upgrade for performance-minded riders. Vents excess crankcase pressure through an integrated breather system. Features an oil separator, perforated disc, replaceable filter element, and umbrella flapper valve. Helps lower engine oil sump levels and improves overall engine efficiency. How Does the Feuling Vented Dipstick Improve Performance? By reducing excess crankcase pressure, this dipstick allows the engine to rev more freely and operate more efficiently, leading to noticeable improvements in performance and fuel economy. Two venting options: Option 1: 1/8 NPT breather vent fitting with an internal porous filter element. Option 2: Quick-disconnect coupler with a rubber hose and external filter element. Helps remove unwanted blowby pressure from the oil tank, preventing excess oil mist. Feuling test results show increased MPG, improved engine response, and reduced oil buildup. How Do You Read the Oil Level with This Dipstick? This dipstick offers two methods for checking oil levels, depending on how the bike is positioned. Full Hot Stand (FHS): When the bike is on the jiffy stand. Full Hot Upright (FHU): When the bike is upright and level. Feuling recommends maintaining 90%-99% full oil levels when hot for optimal performance. Is the Feuling Vented Dipstick Easy to Install? Designed as a direct replacement for the stock dipstick, installation is simple and requires no modifications. Screws directly into the factory oil fill spout. Made in the USA with high-quality materials for durability. Note: The dipstick gets hot; use a glove when checking the oil level.
