K&N KN171B Oil Filter

K&N Oil Filters are perfect for use with high-end synthetic motor oil. Synthetic motor oil is known for its ability to flow better in cold temperatures and provide excellent protection against thermal degradation. These oil filters are designed to allow for optimal flow with minimal pressure drop, while still offering exceptional filtration that meets or exceeds all OEM specifications. Originally developed for demanding auto race applications, our premium oil filter has quickly become popular among consumers due to its durability and ease of removal. In addition, these oil filters are backed by a limited warranty ensuring they are free from defects in materials and workmanship when properly installed and replaced according to the manufacturer's recommended service intervals.

K&N oil filters are equipped with a heavy-duty metal can featuring a 17mm nut on the end for easy installation and removal. The 17mm nut is also cross-drilled, allowing racers to safety wire the filter to their bike. The oil filter has a height of 4.055'' (103 mm), weighs 0.8 lb (0.4 kg), and has an outside diameter of 2.98'' (76 mm).

In addition, these oil filters include an anti-drain back valve (where applicable), which eliminates dry starts and prevents oil from draining back into the crankcase when the engine is shut down. The internally lubricated gasket ensures a tight seal while still allowing for easy removal and installation of the filter. Rolled threads provide added protection against stripping, ensuring that the filter will securely stay in place. With its heavy-duty construction, K&N oil filters are a reliable choice for your vehicle's maintenance needs.
