    I bought my pro es based in part upon how it handled - including breaking performance, the superiority of which over its competition due in part to the fact that it comes with four wheel discs.

    I'm not alone.

    The pro's niche relative to its competition is very clearly derived from its sporty image. An image helped by four wheel discs. An image for which the choice of stock air filter doesn't matter to anyone anywhere.

    Having established the car in this niche, now comes the cost benefit analysis from the consumer's side - the consumer wants rear discs, so how much will it cost to get rear drums swapped if discs are standard? Too much - it would be much better to get them as standard equipment. The consumer wants K&N style performance (whether that be sound, hp, mpg, etc.). How much will that cost to switch if K&Ns aren't standard? Nothing? You mean I'll actually save money by switching?

    I put one into my 2001 Protege about a year ago. I remember it was about $30.

    I can say that after I put it in I could tell a difference in the engine at higher revs, like over 3500 or so. The engine revved a lot smoother.

    Now, I have not noticed any difference in gas mileage or acceleration. But, the improvement to what I consider quite a raucous and unrefined engine was worth it for me.

    I didn't even infer that its products were outdated. What I'm saying is that they were invented during the muscle car era, when everyone was looking for ways to "supe up" everything on cars -- whether it was for performance or just show. C'mon. I'm not out to get you.

    There's another aspect about the difference between K&N and stock air filters.

    I can buy a new $12.95 Purolator filter every year and pop it in my filter canister. Simple. With a K&N, I have to take it out, wash it, and "re-oil" it. (I just read this at K&N's website.)

    While I admit I have no idea what you wash it IN or WITH, I'd have to say that the sludge and used oil you're washing down the drain or leaving in the groundwater offsets K&N's so-called "environmental friendliness" gained from keeping paper air filters out of landfills (which are designed to handle decaying paper much better than the soil in our back yards is designed to handle oil and detergents).

    But I do know that it's a lot less hassle just to buy a paper filter and pop it in than it is to launder and "re-oil" a reusable filter. If you don't agree, let's have a timed race and see which is more convenient. I'll even add you the three minutes I'll use to pull into Advance on the way home and pick up my new filter.

    No, I'm not saying the K&N is outdated. (I think Paul said that.) I'm saying it's unnecessary.

    "An image for which the choice of stock air filter doesn't matter to anyone anywhere."

    Thank you for summing up my point exactly!

    With that I'm going home, satisfied that Protege will be No. 1 tomorrow because of my newest nasty debate started and a job well done.

    I await my congratulatory letter. :D

    It's 81 and sunny out. Time to plop into my cruddy-paper-filter-equipped, 53,000-miles-on-its-OEM-brakes, rear-drum-equipped 2000 ES and zoom happily home.

    Just another agree to disagree thing in the Protege family :D

    One other thing I didn't much care for was how messy the K&N was when I was installing it. The oil was all over the place inside the package, the box it came in, and on the filter as well.

    And I didn't say the K&N was outdated, I said it was now priced lower because they're more commonplace.

    Now you did it. For disagreeing, you'll be tomorrow's all knowing king Tut, regardless of logic.

    That's just crazy talk! be on-topic (now that's a crazy idea!) the new intake I installed in my Pro is great IMO. Much better than the stock intake.
  • Did you disconnect the battery to reset the engine control computer after you installed the K&N? If not, the air/fuel ratio may have been incorrect, explaining the lowered fuel economy.
  • manavimanavi Posts: 150
    I don't remember reading anywhere in the K&N air filter package I bought about needing to reset the car's computer after installing the filter. Where did you get that info?
  • protege_fanprotege_fan Posts: 2,405
    "10. Will I need to make adjustments to my vehicle after I install a K&N filter or intake kit?

    On fuel injected vehicles the original equipment manufacturer (OEM) computer and emissions control system will adjust for the increase in air. The OEM computer will adjust immediately if it is reset. Removing the battery cable from the battery for 15 minutes or more should reset it. On some carbureted models you may have to richen the mixture when switching from a paper filter to a K&N air filter or intake kit.

    The computer should adjust over time, but it's apparently immediate if you disconnect the negative terminal on the battery.

    What should be the voltage ouput when the car is in idle from the Alternator, as measured between the two battery terminals?
  • protege_fanprotege_fan Posts: 2,405
    I've been doing some searching...It sounds like it depends on what's on (ie. lights, fans, etc). From what I can tell, it should be somewhere around 14.5-14.8 V.

    Other forums will likely have more info than here.
  • chikoochikoo Posts: 3,008
    I would appreciate if somebody can back up what PF said.
  • protege_fanprotege_fan Posts: 2,405
    Mind if I ask what the reason you need the info for?
  • manavimanavi Posts: 150
    I guess I won't bother unplugging the battery now since it's been about a year since I installed the filter.

    I still feel comfortable recommending the K&N air filter to anyone who thinks the engine sounds too rough when revving high. But, don't expect any significant gains in MPG or acceleration.
  • chikoochikoo Posts: 3,008
    because at idle, the tach is not steady, and drops and fluctuates when i put in in R(with the rear lights coming on) and drops further when I switch on my lights.

    Anyway I got a battery and alternator tester from Radioshack while coming home for $5.99. It shows the Battery as fine, Alternator as weak.

    So the question is:
    Is the repair of a weak alternator covered under the Mazda Extended care warranty?

    To install this filter?

    Hmmm, we'll have to add time for reprogramming all of our radio presets and clock to that installation time ...

    Tell me, do we have to do this each time we wash and wax the filter too?

    i don't check the forum for a day, and all this madness surrounding my little filter popped up?

    oh the drama!

    good work keeping the post count up Meade :-)
