*insane nonsense rant warning*
Ok I'm fully against "cold air intakes" but I have been a fan of using k&n filters (direct replacements, not cone filters or nonsense). I am well aware that if you don't know how to oil them properly they can mess up your maf sensor. But I don't drive in dusty conditions so I like being able to take it out and clean it whenever and throw it back in.
Been using K&N filters in everything for 20 years. Recently I'm fighting with my truck over fuel trims being high. I said lemme try something and stuck a motorcraft paper filter in it. (It's had a K&N since 2009). Fuel trims came down and evened out across the throttle range.
So... here's my thought here. Given positive fuel trims, the k&n filter obviously flowed more air than the ford filter. BUT do those numbers equate to a power increase or just reduced fuel consumption when dealing with a modern sophisticated efi system?
