K&N KN171B Oil Filter

K&N Oil Filters are perfect for high-end synthetic motor oil, providing improved flow performance at cold temperatures and superior protection against thermal degradation. Engineered for ultimate flow with less pressure drop, they also meet or exceed all OEM specifications for outstanding filtration. Originally developed for demanding auto race applications, our premium oil filter is rapidly becoming a favorite among consumers for its durability and ease of removal. It is covered by a limited warranty to be free from defects in materials and workmanship when installed and replaced using engine and equipment manufacturers' recommended service intervals.

K&N oil filters feature a heavy-duty metal can with a 17mm nut affixed onto the end, allowing for easy installation and removal. The 17mm nut is crossed-drilled for racers to safety wire the filter to their bike. The oil filter has a height of 4.055'' (103 mm), a weight of 0.8 lb (0.4 kg), and an outside diameter of 2.98'' (76 mm). Additionally, an anti-drainback valve (where applicable) eliminates dry starts and prevents oil from draining back into the crankcase during engine shutdown. The internally lubricated gasket provides a positive seal while allowing for easy on and off of the filter, while the rolled threads provide extra protection against stripping. The heavy-duty construction ensures long-lasting performance.

In conclusion, K&N Oil Filters are the perfect choice for those using high-end synthetic motor oil, offering not only superior protection and flow performance, but also ease of installation and durability.
