Replying to: joe131 (May 29, 2007 8:23 pm) I've heard good things about them. Are you using them in all your cars now and recommending them to family members too? I cannot tell if you are serious or not? But if you are, here goes. Added to what I have said above in posts number 133 and 140, I have used them in the past, but only on modified cars that did not have factory air boxes or room for them. Examples are my supercharged Impala SS 385" "full race" sedan, my '78 turbocharged diesel rabbit, or my turbocharged 77 Honda Civic (2 valve head) model to name a few! Many of these cars were modified when I was younger and more foolish and had a few bucks to waste!  Many have heard good things about K & N air filters, but I cannot prove what they are saying to be true. But there are those of us who know of people who have had problems while using them, and some pretty knowledgeable mechanics and "tuners" have written volumes about why NOT to use them. Sadly, I never did an oil analysis on any of my cars that had their filters. I would bet that many who do use 'em will find that their oil will contain very high levels of silicon (dirt!) I do not recommend them to anyone, even those people that I do not like! If anyone would care to read where I got some of the information I know, please email me and ask.

Have you ever driven a regular car at higher elevation. You will notice a significant drop in power because the car is starving for air. Have you ever looked at a K&N air filter. There is almost nothing to restrict the airflow to the engine. If your're running in low range manuevering around a tight switchback on Black Bear Pass you'd be glad you had a K&N filter. Don't knock what you don't know. Fools born every minute. Are you one of them? I was merely stating facts that I know. You seem to be having a bad day and attacking other people for something you know nothing about. Drive your car up Pike's Peak, it's an easy road, I think you could handle it and watch the drop in power. Good luck to you and I hope you have a better day.

There is almost nothing to restrict the airflow to the engine. If your're running in low range manuevering around a tight switchback on Black Bear Pass you'd be glad you had a K&N filter. I would ask one thing: How old are you young fellow? You are entitled to your opinion and that is good. I'll bet I've got many more years experience at this then you do I am sure. I drove up Pikes' Peak the first time in 1952. You? Any vehicle will loose power going that high in altitude due to there being only 17 inches of pressure. Didn't know that little fact did you? Have you ever driven up Love Land Pass in an Eagle and had to stop and take the air filter out because your 8V71 was dying because it couldn't get any air due to the fact that the mechanics had not cleaned the air filter for how long? Have you ever run any vehicle on a dyno. with or without any filter and recorded any differences in engine output? Well I done all that and more, and no, I am not having a bad day! Like I said, I am only trying to enlighten you and any others that may or may not be interested. If you want to believe me or not, that is entirely up to you. It is, after all, your car and your money. Continue to believe anything you like. You sound like one of those thinkers' that doesn't want to believe anything other than your beliefs no matter what is pointed out to you. Carry on, and good luck.

Replying to: derrelhgreen (May 30, 2007 11:06 am) I have seen a K&N filter and I can see how it would not be as restrictive as a regular filter, but...I never thought about the oil used on the filter possibly causing damange to the MAF. Then again, the manager of the service dept. I frequent has stated that changing to a K&N filter would be a good move on my car. When I go in to get the transmission flushed on Friday, I'll ask more questions about the oil messing with the MAF. Before considering the K&N, I was thinking about a CAI, but...the Azera already has that. Would an aftermarket CAI be less restrictive than the factory set-up? If there is no power change between filtered and unfiltered, I would think that more air to the engine would allow the engine to perform a little more efficiently. Would I be wrong in thinking as such?

Replying to: derrelhgreen (May 30, 2007 11:06 am) Your 100% correct Over the years I have bought the K&N B.S. and all I saw was $$$ wasted. Oh by the way K&N lovers I have a special formula for changing lead into Gold :=) |

Replying to: allmet33 (May 30, 2007 12:34 pm) would allow the engine to perform a little more efficiently. Would I be wrong in thinking as such? Yes, I'm afraid so. You already have more than enough air unless your factory stock air filter is completely plugged up, and in that case, you would be experiencing power loss and poor fuel economy big time. If you already have more air now than the motor can use, why would providing even more do you any good? The idea supposedly with the K & N is that there will be less restriction and you will therefore gain power and economy with even more air, which is pure nonsense. To gain more power, you will have to introduce more fuel, and how would that improve your fuel economy? Without some type of forced induction such as a turbocharger or supercharger, how are you going to introduce more air into the cylinders? If you already have a factory air filtering system that is efficient and it is providing you with more air than is required, how will adding a larger air filter give you any gain? Think about it!  BTW, any gain from a CAI is provided not by it being less restrictive, but by it supposedly allowing cooler air to be drawn into the cylinders. The cooler the intake air, the more Oxygen it contains. Have you noticed how much more powerful your car seems on a cold day vs a hot summer day?

Replying to: derrelhgreen (May 30, 2007 9:06 pm) Right again!. The optimum fuel air mixture has been determined by the engineers who developed the engine. The air intake is designed to accomodate that mixture. The addition of more static air will not change the desirable mixture. Forced air can be advantageous, but the mixture would be adjusted to accomodate that increase in air pressure. Most independent tests have proven that the aftermarket air filters are more hype than performance.

Replying to: floridabob1 (May 31, 2007 2:26 am) I have also seen performance increases ( without a CAI ) with the installation of a colder thermostat in order to keep underhood temperatures lower. I don't drive on dirt roads, and have hardly ever changed an air filter, their capacity for air is way more than the engine needs. |
