$10 K&N filter vs. $30 OEM

I just want to make sure the K&N fits and verify the part number before ordering 10 of them.

I installed a K&N KN-159 a few days ago on a 1299 base. It pops on the nipple just fine and seems to fit better than the stock ones I remember. My bad, I should have taken pictures, or a video to show how well it fits over the nipple. I've installed a few different types of filters on the 1199 and a K&N on the 1299. The fitment is very positive on the K&N (1199,1299.) Additionally, that cover plate is made to hold the filter in place over the nipple.

I did compare the:

stock 312B (came out of 1299,)
291C (bought couple years ago from dealer for 1199,)
and KN-159 (started using last year on 1199)

standing up on the bottom plate and examined the rubber o-ring that fits over the nipple inside the engine. The 291C (old filter, dealers told to sell out of before selling 312B,) has a couple of o-ring type ridges on the inside of the rubber part. The 312B (current 1199 and 1299 filter,) and K&N KN-159 are almost identical in terms of how the rubber piece looks.

Another user is going to use a digital caliper to measure the differences. There will be differences, but they will be slight differences. I dont think enough for any of us to worry about. The K&N has been in my bike now for 50 miles and not causing any lights or problems and I know it wont as it is the aftermarket replacement filter made for the 1299.

I got mine from Amazon in two days :)

Thats the best place I've found to order them. They're about $10.00 plus tax. If anyone has found them cheaper, let us know! Honestly, cant get much cheaper for a superior aftrmarket product (compared to OEM.) I had the receipt for a filter I picked up a couple years ago for $35.00 from the dealer... FOR ONE.

Chris, the part number changed but fitment remained the same. It's the same part number now for 1199 and 1299 so you shouldn't have any trouble with the K&N.
 
i'm guessing that most dealers didn't know of the oil filter part number change, that's why they told new buyers of the bike that it was a different filter... i'm guessing.

i'm pretty confident now that 291C and 312B are compatible, and will be using the K&N from now on. the 899 ndicates the usage of 312B as well
 
I have had numerous engine builders tell me to NOT use them. I cant remember why now as it has been a few years. But they specifically told me to use the disposable ones.
 
I used a washable K&N stainless mesh fuel filter years ago - same principle - seemed to work ok but when it got loaded pressure drop increased rapidly, plus I don't think they filter quite as well. Interestingly, K&N dropped the product not long after introducing it.
 
I just put in a K&N filter and reused the crush washer and all is good. :D

While its not a life or death situation, (and you probably already know this, but for anyone else reading) the washers used on the oil drain plug in the 899 1199 and 1299 are consider "crush washers."

Along with all vehicles that utilize a crush washer, they are meant to be a one time use item. Most shops include the washer with the oil filter as standard practice for replacement.

While you can probably get away with it, I've seen adverse effects of reusing a crush washer and over tightening the oil plug (slow leak and stripped out bolt.)

If you choose to reuse a crush washer, DO NOT OVER TIGHTEN.

Crush washers a malleable pieces of metal designed to form and change shape when pressure is applied to them by tightening the plug. They remove pressure from the drain plug threads and the replacement of them will improve the life of the threads.
 
I read somewhere that you can freeze a crush washer, then defrost it to reuse it

But that you should only do this twice.

Personally, I bought 3 of them when I bought my filter. But, I keep wondering if this trick really works.

No. As pointed out, heat 'em up with a standard home depot - type propane torch until they're glowing red then drop 'em in to a bucket of water. You can reuse them over and over and over....

Or visit your local auto parts store. I went years ago when I was changing filters/oil every week (racing) and they gave me handful's for a couple of dollars. Still use them.
 
Use them on the cars, too - fit fine

Reusing crush washers is asking for drips on your clean concrete, no thanks

Would it be blasphemy to say that I have never changed a crush washer in my life, on any bike? :D

I know you are technically supposed to, but I never have. But I don't gorilla the drain plug on either.
