Talking about when to change your oil and what oil filter to use can spark arguments where both sides defend their positions with religious fervor. Nevertheless, let’s forget about the marketing hype for a minute and recognize K&N for their simple innovation that should be standard on all oil filters: they’ve eliminated the need for special filter wrenches by welding 1″ nuts to the top of their automotive and marine filter canisters and 17mm nuts to their motorcycle and ATV canister filters.
No more strap wrenches, contraptions that look like they came from a claw-game, or pliers with gaping jaws to remove and replace your oil filter. For K&N Wrench-Off oil filters all you need is a standard 1″ or 17mm wrench or ratchet.
Street pricing on these filters runs from $7 to $15.
