Given the dusty conditions in this area (lots of construction), replacement of paper filters in both spring & fall is the norm. I'm still on that original K&N and have spent an additional $10 for the cleaning kit. Total cost: $54 + tax. If I had thought your way I'd have spent $288 + tax (over $300 total) with more to come. At about one sixth the cost of air filters, my wallet prefers my thinking to yours. So does the ecologist in me who has not seen an extra 16 filters go to the land fill. I was never too concerned about perceived increases in power or economy. If there was a change in power it was not detected. My fuel economy, though, has been quite good. EPA rated at 19/27 (17/25 under the revised rating), I consistently get 24.5 in city driving and 26-28 highway. |

Replying to: derrelhgreen (May 31, 2007 7:36 am) Internal combustion engines are most efficient when the internal heat is at the highest possible temperature. The cooling system is employed due to the fact that the materials used in the construction of the engine have limits to their ability to remain stable at extreme temperatures. Most engine manufactures have been experimenting for years on ceramic engines that can operate at extremely high internal temperatures. These engines have proven to be extremely efficient with much lower fuel consumption. |

Remember how you could hear that big four barrel carburetor enjoying that extra oxygen? The same principle is involved. If you don't drive at altitude then a K&N is of probably no use to you. However, K&Ns have their place. Even the sticker has value because you don't have the guy at the instant oil change place trying to sell you an overpriced paper filter element that you might happen to buy on impule.

Replying to: pahefner01 (May 31, 2007 3:01 pm) Yeah, oxygen burns with the gas. I expect the hydrogen and nitrogen burn there too. So? So you think that big 4-barrel was enjoying extra oxygen when you took the air filter element out of the housing? And you think that because you could "hear" it enjoying it? Not hardly! It was just extra noise you were hearing since the air was making a racket bouncing around in the empty housing as it made its way into the carb. Oh, a little bit of that extra noise may have been the internal engine parts being ground down by the abrasive particles in that unfiltered air you were "treating" your engine to. (Mom, can I have another Snickers bar with my 44 oz. Big Gulp?) Except for that one guy who posted earlier, sounds like K&N filters are a waste of time and money. And if anyone trys to sell you an overpriced anything, just say no. You don't need no steenking stickers talking for you. |

Replying to: joe131 (May 31, 2007 3:25 pm) Right again! At altitude the air is thinner. The percentages of nitrogen, hydrogen and oxygen does not change. A turbo charger forces more air into the system. The fuel injector are more precise in injecting a metered amount of fuel into the cylinder than the carb. The engine computers utilized in todays engines are capable of adjusting the mixture and timing thru a series of oxygen sensors. These were not utilized in the old muscle cars. |

But as one thinking person to another, I would ask why you are changing your filter twice a year? You must pay $18 dollars for a replacement filter? I just bought a Purolator for my Focus today that was a coupon special at Pep Boys for $7.53 including tax. It will be the first air filter change in seven years and 36K miles. I haven't looked at the original paper element for some time, but I'll bet that it's still good and still serviceable. So for the cost of $54 plus tax, how long at the rate I change filters will it take me to "break even?" The poor old Focus will be in the landfill long before wouldn't you say? Now let us say that if I were to start using a K & N filter and the oil from it were to ruin my MAF as has happened to many TDI vehicles as reported over on Freds.' Priced a MAFs for your car lately? If you were to even know what the little electrical part costs, I doubt that you would gamble that against your perceived savings. Unless you drive on dirt roads all the time or are off-road all the time, why are you changing your air filter so often? Are you one of those drivers that changes your engine oil every three thousand miles also? BTW, Pep Boys does not carry or show any listings for air filters for the Azera. Purolator does list one for the Azera, but Pep Boys just doesn't stock it. Now as far as paper air filters clogging up our landfills, do you read a newspaper? How about paper barrel bags from the grocery store? We are talking paper here, not radio-active waste! Carry on and good luck.

Replying to: allmet33 (May 31, 2007 8:40 am) cylinder between using a regular filter as opposed to one that's less restrictive?" Yes. What do you mean by less restrictive? Less than what? There is virtually no restriction in a properly designed air box with an original paper element filter installed within that isn't completely or partially plugged. I have tested an Impala SS with and without any air filter element in the box. There was no difference in power output. The original filter I removed was used for 17K miles, so it was not brand new. BTW, that air filter box had extra holes drilled in it to increase the air flow to the filter. Didn't want to rely on the single somewhat smaller air intake leading to the filter. Many in our SS group were doing that simple modification. For those who would like to know just how much restriction there is in their own set up no matter what filter is being used, try: http://www.filterminder.com/fleet/howfilterminderswork.asp And if you still want to know more about WHY NOT TO USE any other filter other than a good stock paper element, read: http://forums.tdiclub.com/showthread.php?t=174067&highlight=air+filter+restriction+gauge Now IF the information there doesn't get you to at least Think About It well, what can I say? BTW, notice how many individuals belong to Freds.' Also, how long that forum has been up and running. There are some really smart fellows there, and they do know one hell of a lot more than yours' truly!

Replying to: joe131 (May 31, 2007 3:25 pm) Have you ever been to the NHRA races and watched the naturally aspirated Pro Stocks run. Are you aware that they make less horsepower at altitude? Do you think they are running paper air filter elements. As previously stated unless you've driven at altitude you have no idea what difference a K&N filter makes. It makes a difference. If your theory on the noise of a Carter AFB running unrestricted as being air bouncing around in the empty chamber and abrasive particles grinding the engine to shreds you may have another Snickers Bar and a 44 oz Big Gulp. Give it a rest. Why did muscle cars have air induction? Buy whatever air filter you want and waste your money on paper but please give us a break. You've made your dislike of K&N filters well known. Trying to prove your dislike using warped science isn't necessary. We know you don't like them and we don't care.
