My point being, I was ready to buy a K&N air filter. K&N Powersports Cartridge Oil Filters are designed to satisfy the needs of racers and engine builders as well as the average motorcycle or ATV owner who. I work for an automotive company, but I'm not that into my car. The representative continued to explain the company's lengthy product testing process. Of the 2,500,000 filters K&N sells a year, they encounter less than 200 dealership problems annually. Where would all this "excess" oil come from? Hmmm. But I looked at the cone-shaped piece in the man's hands. Mechanics are telling customers that MAF readings show it is "saturated" with oil from the K&N filter. Is the filter fouling the MAF or is the MAF flawed? It is just as likely that the MAF comes defective from the factory. It is much more likely for oil from the engine to get sucked through the intake and foul the MAF. Do you know what is constantly cycling through the engine? You got it- oil. The MAF is fouled by oil right? Well, the MAF is in the engine. Even if you were driving 103mph and held a grease covered napkin out the window, the oil wouldn't come off-trust me.

Mechanics are claiming that the oil from the filter is coming off the paper an affecting the MAF. The filter absorbs the oil, which coats it for protection, and is invisible. The napkin absorbs the grease, practically making the paper transparent. If you haven't, I will give you the low down. Have you ever gotten a really greasy piece of pizza and blotted it with a napkin. The paper, which is the filter, is coated in oil. It attaches to a hose that brings air into the engine blocking dirt, bugs, and any other hazardous objects that happen to make their way under your hood. It is cone shaped part, basically constructed of a paper filter with wire mesh around it. If you are not familiar with what a K&N filter looks like, let me explain. The K&N representative, however, gave a compelling argument. What causes MAF problems? The dealerships claim excess oil from K&N filters is to blame. People around the country are bringing their cars to dealerships and mechanics with MAF(Mass Air Flow Sensor) problems.

Maybe it was the excitement in his words or the sweat dripping down his face, but I could tell he wasn't faking. But you know what? The guy knew what he was talking about.
