7 HP and Ft/Lbs from a drop in K&N?

Manning said:
For what it's worth.......I've read that the K&N does indeed flow well, but doesn't filter well. This was from the wacko diesel guys that have their oil analyzed at every change, and with the K&N they had high amounts of silica (sand) in the oil. Change the filter out for something else, the silica content in the oil went down.

I could have made this exact post! Strange! But change the diesel part to gas motor. I've read so much on bobistheoilguy.com

Silica comes from the oil used to make the filter work. It should be known that K&N filters don't filter shit until they're all gunked up. At first they allow oil to get sucked in (from over oiling), then they breathe freely, then they get all gunked up, then they filter good. I've stuck with paper filters after learning about all that.

I would assert that the silica is the dirt itself, not originating from the oil- but coming through the poor filtration. Oil with silica would not be a good thing. Silicone in oil can be found in small amounts as an anti-foam additive. Silica is a component of dirt which causes abrasive wear. Silica and silicates are the basis of sand and nearly all rocks. When silica combines with carbon- the abrasive qualities are astoundingly worse and guess what's also in engine oil?
 
It's been a long time (well not really, but it's gone from the memory banks) since I've read about all this, but I was under the impression it was directly from the exact oil K&N used. Almost to the point that the lab (be it Blackstone or whatever) could tell you that you are using too much oil on your filter. Like they knew.

I might have been mistaken, and it might be silicone.

I just can't remember!!!
