Has anyone had real world experience with these things?

I read the stainless oil filter post and someone tried the K and P.

These filters almost sound too good to be true. I know Pure Power makes quality products for aircraft etc.

Anyone?

I was due for an oil change ( 15 K ) when I read the article in Hot Bike, so I ordered one. I've had it on for about 1K miles, and the only thing I am 100% sure of is I'm out $200.    It looks cool, and I'll never have to buy another filter, but the butt dyno doesn't feel squat, and I don't have a temp gauge, so don't know about temps being any cooler. I didn't go for their oil. Didn't want to to go with 15/40. So, I guess you could say I'm happy. It took me a few tries to get the torque right. Guess I was over tightening it, cause it had a drip. I finally backed it off and stopped the leak. It certainly is a very high quality piece of craftsmanship if nothing else.

My feeling about the K&P and the Pure Power filters is that I wouldn't trust them until I see independent testing that verifies they are at least as good as the paper filters in cleaning particles from the oil (which is, after all, the primary function of an oil filter).  So far I haven't seen anything from either company, and definitely not from an independent source, that proves with oil analysis results after 5k miles with a paper filter and after 5k miles with the S/S filter that the S/S filter is as good or better.

The horsepower claims from Pure Power (blindly passed along by a couple of bike mags) are based on reduced pumping losses through the S/S filter (it takes power to force oil through the filter and through all the oil passages).  They do not explain how they achieve less restriction than paper filters without allowing more crap to pass through.  They also tend to gloss over the fact that their results were obtained with lighter oil (40 wt vs 50 wt), which none of us would want to use in these hot running engines.  When BikeWorks fell all over themselves a few months back singing the praises of this system, I shot an email to the editor suggesting they were doing the readers a disservice by making it seem like they were making the claims and not just passing along the claims of an advertiser.  I pointed out the lighter weight oil, and then suggested they just take the guts out of a stock filter if they want max power from reduced pumping losses, and save the $200.  Needless to say, I didn't get a response.

The fact that these companies claim racers use their filters (NASCAR, etc.) really isn't all that impressive when you think about the fact that a racing engine only has to last for one race.  Lower restriction would trump better filtration when you know you'll be rebuilding the engine every 500 miles.

I think the idea is agreat to be able to clean it and over the course of 15 oil changes or 37500 miles you would pay for the filter. I based this on 13.99 for a chrome filter if you use black you have even more miles to pay it off.  And the claim of increase power??  FUNNY stuff , I have seen testing done on parts in a shop I used to work at where they rented the dyno for testing with us running it for them. They would start with a cold engine has us make 1 pull that was there base line, then they would install there magic part and have us do 5-9 more pulls as the engine is getting hot , air pressure in the tire is raising the engine is making more power they us that figure to show the public .

Great insight.  Sometimes the Nascar engines do not even last one race and they must be running as hot as my SE 110"

I have the K&P filter and I would recommend it to anyone who doesn't mind cleaning it.  I have cleaned it a few times now and I am satisfied.  It looks great too.  As far as the claims of increased hp, etc, I don't believe it nor do I care, I bought it because I liked it and from what I have seen it filters oil just as well as a paper filter.  No oil analysis here, JMHO for what it is worth.
