K&N powersports oil filters contain a modern synthetic filter media, designed for ultimate flow with less pressure drop, yet engineered for outstanding filtration. K&N powersports 'spin-on' oil filters feature a heavy-duty metal can. Most of these have a 17 mm nut affixed onto the end that allows for easy installation and removal. The 17 mm nut is crossed-drilled so racers can safety wire the filter to their bike.

Product Reviews

  The incorporated nut on this filter makes it easy to remove and install without special tools. I've used OEM filters in the past and they are a pain in the rear to remove and install.

  I only use K & N OIL AND AIR FILTERS IN MY CAR & MY MOTORCYCLES because they are the best you can buy. You can wash out the air filter once a 1/4 and use the Recharger kit, I have had the same K&N Air filter since 2006 in my 2053 cc 125 ci Kawasaki high performance cruiser Motorcycle and just use the recharge kit every 90 days .The oil Filter I use for a whole year no matter how much I use the bike. I use a high quality fully synthetic max cycle purple oil. Oil looks new when drained out. I buy 5 filters at a time for my two bikes. The 2006 uses the KN-205 the other 2008 uses the KN-303. Want the best use K&N OIL, AIR, CRANK CASE VENT FILTER, IN LINE FUEL FILTERS.

  Excellent product as are all K&N products I have used. Easy to install with built in hex nut. Only filters I will ever use.

  I cannot tell you how happy I am to do oil filter changes with this oil filter. The nut on the end makes it extremely easy to uninstall. I have never had any issues with this product's performance or durability. I would recommend it to anyone.

  Had 2 into one V&H pipes & re-jetted carbs at Honda on my bike, '05 VT1100C2 Shadow Sabre. Sounded good but was still missing some power. Recent oil change to K&N oil filter and air filter. The air flow was the fix, more torque, more top end power. Fuel mileage should be better also, if I would ever ride at a normal speed.
