    True, but i am more concerned about having better filtration than having 2 horsepower. It is good for racing engines because they are going to have to be rebuilt after a few races, so its not going to matter if junk gets in there.

    Jason,
    I think we went over the vacuum gauge issue before, didn't we?
    An average gauge that you would buy in an auto parts store will never have the sensitivity to prove what you want to prove.
    The OEM uses platinum plugs for EXACTLY one reason, to keep people out of the engine bay. Are they anywhere near the best fpr performance? HELL NO! Platinum is actually a rather poor conductor, especially as compared to other plug tips. It just happens to be durable.
    As for the paper vs. reusable media air filters, there are several reasons why the OEM uses paper:
    1. price
    2. ease of replacement
    3. gives service departments something to charge for on every service visit.
    4. the filtration capability of the media is NOT dependant on proper specific service techniques.
    5. reusable media filters require cleaning and oiling which produces hazardous waste.
    6. if improperly serviced, the reusable filter media can constitute a rather sizable intake restriction thereby decreasing MPG and performance.
    7. excess oil CAN coat MAF sensor and thereby adversely affect the sensors ability to properly regulate air/fuel mixture.

    Overall, as you pointed out, the paper filter will provide "adequate" airflow to the engine but, in the upper rev-range they can (and generally do) provide a degree of airflow restriction. This is why they are so popular among the performance crowd. You're right, you will have negligable performance increase in lower rev-range from a higher flowing filter regardless of what filter media is used because the flow REQUIREMENTS of the engine are well within the capabilities of the more restrictive filter. Hell, if all you did was drive around all day in city traffic, you could strap a lawn-mower filter to it and it would be fine.
    I have never found ANY experienced technicians that would argue the point that an oiled filter media air filter is NOT superior to a plain paper filter. So the point is, not whether the one is BETTER than the other but, whether one is more user-freindly than the other. The oiled, reusable filter IMHO is a better filter in virtually everyway. It just requires a little bit more "proper" maintenance.

    If there's anything else to say about K&N filters vs. OEM paper filters, I'd like to hear it now. Otherwise, let's talk about something REALLY important, like......which is better, beer, or tequila

    "To each his own" I guess is all that's left to be said. As long as whatever you do makes you happy...

    Me? I prefer a stiff margarita. I choose tequilla over beer.
