The conspiracy theoristas are already hard at work attacking the study. Good luck, since it was impeccably conducted. |

Good stuff, just am curious about the Donaldson Edurance filters and
how they perform under these tests? RH |

Good luck, since it was impeccably conducted. > Actually the study results for % efficiency are very similar to what was at one time posted on the K&N website (don't know if it still is). K&N did report that paper filters had a typical filtration efficiency of 98% and that K&N were about 96%. As presented, and with just that one bit of info (not all the other tests in SPICER.htm) they said that for the slight increase in dirt being passed, the 2% difference, you got the big benefits of increased airflow. I never bought it but on the surface it doesn't sound like you are losing a whole lot if your primary goal is the extra 2 to 4 hp you might get at wide open throttle. When you see all the other poor results you'd be nuts to use a K&N - but I"m sure that this study won't slow their sales down one bit. -- Elbridge Gerry, of Massachusetts: "What, sir, is the use of militia? It is to prevent the establishment of a standing army, the bane of liberty. . . Whenever Government means to invade the rights and liberties of the people, they always attempt to destroy the militia, in order to raise a standing army upon its ruins." -- Debate, U.S. House of Representatives, August 17, 1789 |

So buying German does seem to give some amount of assurance that you are getting at least an acceptable quality product. Now whether it's *superior* or not, that's another question entirely. nate |
