I thought K&N was still made in the US. Being made in China is not for me. I will order a filter from Zip Ty next month. I want to support a filter company made in the USA and supporting a company that supports our sport.
I agree, but I could not find a filter from them??? I will definitely buy the 22mm oil drain plug as mine is worn.
K&P Stainless Steel Filter for Terra Wanted to let you guys know that I spoke with the owner over at K&P Engineering on Monday. He tells me that their stainless steel filters have the equivalent filter capacity of 4 micron paper while still maintaining 7 times the flow. This far exceeds OEM, Hiflow and K&N filters.

I thought we went over this once before 35 microns is not that good. BMW voids the warranty with that filter, at least that is what my dealer says. Topic here http://www.cafehusky.com/threads/scotts-stainless-oil-filter.35683/ #2151 K&P Stainless Steel Reusable Oil Filter. Superiour filtration for your F650 1997 - 2011 and Husqvarna TR650. This filter covers all BMW part numbers for these models. Filtration 35 microns absolute, greater surface area & over 7 times the flow rate of paper filters. Will not wear out & guaranteed for life. Easily cleaned & monitor your engine for problems as you do so. Genuine USA Made by K&P Engineering.
35 microns stainless steel is very good, it has the equilance of 4 microns in paper. Hiflo and K&N filters are no where near as absolute.
This makes no sense. 35 microns absolute will only filter out 35 micron and larger particles. A 4 micron nominal filter even at 50% efficiency will filter out half of all particles 4 micron or larger on average. I use a stainless filter for the flow efficiency and just change my oil very often, but the reality is a 35 micron absolute filter is stopping none of the 15-20 micron particles that actually cause wear in a modern engine.
That's what K&P said. When testing against paper in average particulate reduction, their stainless steel filters had a 4 micron paper equivalence. For real world testing, Ty's 501 racing engine went through 59 hours of hard run time and was torn down to find zero wear. My KTM 500 has had nothing but K&P filters and has over 6000 race miles.
500 hours at 60 mph = 30,000 miles. 59 hours is nothing. I really don't expect to be tearing down my bike even at 500 hours. At 59 hours if you changed the oil after ever race you would have the same results without any filter. Sure, the kp151 is better than running nothing, I will give you that. It will catch a stray metal chip etc. It will not stop the carbon abrasion. Oil change and good paper filters do that.
I've read your other posts and realize your disbelief against SS filters. I have first hand knowledge that they work well and won't come apart. Through racing and rebuilding which we do a lot here, probably more Husky engines than anyone else in the world. The SS filter will make the Terra 650 engine last longer accompanied with higher flowing fresh oil.
I've got to ask this. For years I have been resisting the purchase of an SS filter because I don't understand how one cleans it properly. What happens to the smaller particulates when they migrate inboard in the filter? Do they get stuck? If so, is this making the filter less efficient? What do you clean it with? Thanks for indulging me.
I use a little cheapo ultrasonic cleaner with hot, soapy water. I initially blast the oily filter from the inside out with a can of non-chorinated brake cleaner, then drop it in the ultrasonic for a while. Then I take it out, rinse it in hot water, and let it air dry. I've got two filters so I swap them out so I can finish changing the oil without having to wait for a filter.
I thought I was clear on the flow issue. Running with or without a filter in the Terra, will not change the flow PERIOD. That is a function of clearances and pressure. Until the clearances wear out, or you change the pressure or the filter is 80% clogged, the flow is going to be the same. I am not against SS filters in the right applications, but I hardly think 35 micron is good filtration. So what's next Tinken? You going to bash the Evans waterless coolant? I didn't think so. I assure you that you have no idea of my mechanical and technical resume. If I can't convince or educate based on the facts, so be it. If the guys here do not understand how an oiling system works and buy into the glitz and glam, that is their choice. Whatever makes you sleep good. I won't buy a used bike from them. If you change your oil regular, you will be doing your engine a favor, but palease, don't give the credit to an inferior filtration device for the longevity of an engine with regular oil changes.
I have an idea of your mechanical and technical resume if you honestly think there is no pressure drop across filter media. Run whatever filter you like. Sound like you've got a serious case of Tinken envy you need to work out.
First paragraph in your post. I was paying attention, but not anymore. No benefit to it. Enjoy your bike and whatever filter you choose to run in it. I'm setting you to "ignore."
Go reread and put into context please, I am talking about flow. It takes more pressure to increase the flow, and the limiting nozzle so to speak is the engine, not the filter. So, I suppose you could interpret it that way if you wish, and if you did measure, on a good engine, not a worn out garbage engine and with a stock filter vs the ss filter, with pressure gauges before and aft of the filter on the same engine running, I would be willing to bet that the difference if there even was a pressure difference would not even be noticeable. I'll have to draw you a picture so you can understand, now go take your ball and go home, I've got no use for your ignorant lame insults anyway.
Unfortunately your arrogance has bested you. It is clear to both Mike and I that you really have no idea what you are talking about and wish to turn this helpful thread into a fight. I wish you the best of luck with your Husky.
