The cone filter is Ok is it is sealed from the engine compartment, otherwise you are just sucking up hot air. I'm sure you guys know that it's much better to have cooler air going into the engine. You can't actually feel any difference between the cone and the ported air box on a stock engine any how. Anyways, I wouldn't waste my money on a MAF, There is too much talk of those things causing a CEL and a lean condition. I wouldn't even consider it. Sure, I had a conical filter on mine for a while, I went back to the stock ported air box. Cooler air and you can't tell any difference as far as power. If paper filters are so bad and restrictive then why have auto manufactuers been using them for decades? Those K&N filters are really more trouble then they are worth IMO.
