    Do not buy K&N Wrench On oil filters: Busted on me

    20170324_171532[1].jpg20170324_171552[1].jpg

    So I got cute and tried a different type of oil filter, one of those K&N Wrench Offs with a nut on the end for wrenching it on. I'd never used one and never will again. About 2k miles into it, the tab on the top of the filter blew and spewed oil like an artery all over the road. Luckily I was commuting and was close to home. Scared the shit out of me, thought I'd thrown a rod, even though it ran just fine pulling off the road in that plume of smoke.

    Anyway, a word of warning on these filter types. Don't use them. It was even ~more expensive~ than the standard $6 Fram I always use (it was about $14 for the K&N), and I thought it'd be easier to install than trying to wedge my filter wrench in there. Maybe you'll say I over-torqued it, and maybe you're right, but whatever the cause, I don't like having one more failure mode on my machine. So no more nut-filters for me!

    K&N Wrench Off == HELL NO!

    Good one Skid, has anybody set this pic to K&N AM could end up saving many a motorcycle and riders lives. Maybe if we all sent them an email saying their product was shit, might give them something to think about because obviously they don't give a shit

    Yes they are junk!! a bud of mine had two that would not seal at the O ring. He had oil all over his NM4 just taking it down the street. It took us a afternoon cleaning that plastic wrapped V
    ader bike. Then his CBR600 had the same issue. He had bought a case of them and K&N had him send them back if memory serves.

    I had 2 of them start leaking at the nut. This was on my 6th gen, back in 2011/12. Since then I only use Hi Flo filters (or Honda if the dealer does the work). I wouldn't use Fram either.

    What I find incredible is that any member on this forum would even use one after all that has been posted on this site about this terrible product. K&N;s shit performance and dangerous qualities has to be one of the most complained about maintenance part on our bikes. I have never used a K&N oil filter because of all that has been posted here. Maybe we should see if we can get a warning and link somewhere in the header of this site to warn people who still don't seem to get the message.

    In addition to this, why don't those who have had an issue with them not only complain to K&N, but complain in a public manner about the shop that continues to sell to their customers, this piece of crap. Then tell that business that they have lost a customer and why this happened. If merchants stop stocking this piece of crap, maybe K&N will fix the problem or better yet, go out of business.

    the strange thing is I like my K*N air filter on my car, I think it is because K+N just don't want to bother fixing their VFR oil filter

    Hey, he's playing nice. Enjoy it while it lasts.

    I have a K&N AIR filter that came with my bike. I'll never use their oil filters. I told the K&N trip at the IMS Long Beach. He claimed he never heard of problems... I told him to read our forum and VFRD. So they have been made aware of it. Looks like a lawsuit is the only thing they'll listen to. It needs to happen before someone gets killed or paralyzed.

    Oh my...

    I'm so sorry.

    If people don't frequent this place, I can see where they don't get the memo.

    Go into any parts store or online retailer and what's one of the top products that comes up?...this piece of crap.

    And problem is they are reputable for their air filters so who would think twice about questioning oil filter?

    Some suggestions here are spot on:

    Class Action Lawsuit

    Getting pics like mine to come up just as quick as a search for VFR oil filter brings up K&N purchase suggestion

    Take this to a more public place. YouTube? Petition?

    I have no idea. And how do we do it? I could play to my gender on this one and really try to do something...people listen to a "poory" girl their shizz product almost killed ...but guys, I have no idea how to do stuff like that. I'd need help.

    But Imma be PISSED when I hear someone being seriously injured or dead from it.

    The guy who cleaned up my moto in Bozeman, decades of working on motos, said he saw so many engines ruined by these...

    It's not just us here.

    Without proving damages clearly, a lawsuit will get no more than a big lawyer bill. But, yes, these people have a defective design. It's a miracle nobody (we know of) hasn't been hurt.

    Do not buy K&N Wrench On oil filters: Busted on me

    Just for shits and giggles I googled VFR K&N OUL FILTER and the fourth post down was this posted on VFRW.
    Was tryin to somehow post a picture of AM photo
    IMG_0533.JPG





    QUOTE=Rt rider;419567]My gen 6 developed a small oil leak. It seemed to be only when the motor was running. I thought the filter might be loose so I tightened. When I took it out on my test ride after there was smoke trailing. Pulled over and the rear tire was covered in oil. I nursed it home trying not to lean the bike and reduced speed. By te time I pulled back into the garage the oil level was getting toward the bottom of the sight glass. I left the bike running and took a look underneath and then it became obvious.

    The leak was actually coming from the nut that is welded to the end of the filter.

    I have used k&n filters for the last few years on numerous model of motorcycle and cars and have never had an issue. I did a like internet searching and it appears I am not the only person to experience this problem.

    I had an extra k&n filter (it's the same filter on my zx10r). Put it on and no more leaks. I didn't install the orIginal filter but I didn't over tighten when I made my adjustment. I'm going to contact k&n tomorrow to see what they have to say.[/QUOTE]

    I think I deserve some sort of credit for creating that "promotional" graphic based on Jen's photo (but am unlikely to get it from K&N...).

    Are you tightening the filter using the nut?

    I figured the nut was there to get the filter back off. All oil filters that l know of, are all Hand Tighten Only.

    Makes me wonder why you need to have a nut? Seriously you do hand snug and a quarter turn. No need to use a wrench. And that giant nut is sticking out there at the end of some very thin sheet metal that really isn't capable of taking any torque at all. It has to be the worst place ever to put a great big nut!

    I've had good luck luck with K+N filters in general, for a lot of years.

    I've always liked the hole in the nut. Made it easy to safty wire for a track day.

    Although the nut has been problematic for many, it is not the only area where K&N filters have shown to be of questionable reliability. The other area that has been prone to failure is at the O-ring.

    Not sure if it is something that K&N had always made clear, but they do say in the instructions and web site I believe, that the nut was never meant to be used as an installation aid only meant for ease in removal. If they were smart, they would weld on nuts that can only be used as a removal aid. Meaning round the corners of the left edge of the nut, similar to security screws that can only installed, but in reverse, where you can only use it to loosen they nut (filter). This would leave them less likely to have failures from improper installation.

    A total recall or design change would be the ideal or perhaps optimal solution. The Oring failure is most certainly another flaw. There are Orings and there are Orings. The costs are different and maybe somebody along the line figured differently and substituted the "wrong" Oring for what was in the original design criteria.

    Of course, the largest Oring in the world is in Texas...40' in diameter..

    Are we really so stupid that K+N should round off one side of the nut so it can be turned only counter clockwise?

    And as soon as something doesn't right, the Angry Mob screams: Class Action Lawsuit? Great.... Now we get lawyers involved. The price of all oil filters goes up. Then maybe the manufacturers will be forced to put a big, stupid warning on the oil filter. Where does it end? Then the motorcycle manufacturers will have to build motorcycles, that have to be take to an Authorized Service Center to have the oil changed?

    Lube the O ring. Hand tighten only. And if you don't like them, just buy another brand.
