They work well, and help the environment by not having to throw an air filter out every time one is changed. They also seem to add a little kick by offering less resistance to air flow to any engine. I put a UNI-Flow in the DLX until it is broke in, ha ha, and then a K&N will go in, and it may be the last one I may ever buy unless Honda gives us a nice CB 1300 or something that looks like a motorcycle to me.
That is a debatable premise on the basis of the cleaning agents used to clean them and the oil used to "re-sticky" them. After you have cleaned your K&N's do you take the solvent mix they supply for use to the local recycling centre for safe disposal, fair play if you do but I suspect most don't and it ends up in the ground and eventually the water table.
It is a bit like the reusable cup and the china mug. Is the energy used to wash the mug more than the energy expended making and composting the paper cup? - I don't know the answer either.
