While sitting in the K&N info session, following the words of a bald man with a hoarse voice out crying me his best pitch on air filters, I must, “K&N really does care for their customers.”
But, let’s back to the debate. People all over the country are getting their cars to dealerships and mechanics with problems of MAF (Mass air flow sensors). The problem being is mass air flow sensors failure. What actually causes the failure of MAF? The dealerships have claimed that excess oil from K&N filters is the reason.
A very persuading and convincing argument was given by the K&N representative on the claim. A K&N filter is a cone shaped part, constructed of a paper filter with a wire mesh surrounding it. A hose bringing air into the engine is attached to it; blocking dirt, bugs, and any other hazardous objects that find their way under your hood. The paper, which is the filter, is encrusted in oil.
Have you ever tried blotting a really greasy piece of pizza with a napkin? Well if you haven’t, I will give you the low down. The grease is absorbed by the napkin and the napkin turns transparent. Well, so does the paper. The filter absorbs the oil, coating it for protection, and turns invisible. You are unable to see it. The oil coming out from the filter is off the paper and affects the MAF, is what the mechanics are claiming.
