NOPE.

Its proven that EFI cars of today do not benefit from air filter changes. Dirty to clean, and VERY little from low flowing to high flowing. Mass airflow sensor meters incoming air, ecu adjusts everything under the sun to get a handle on its efficiency. You could quite literally stretch 2 gym socks over your MAF and call that an air filter and it would yield the exact same results your K&N did, performance wise. Your figures say you gained %25 more efficiency! I don’t believe that for one second! Because if that was the case, every car from the factory would be sold with a “K&N” like filter because the proffit from the marketing effects would be through the roof! “don’t buy a camery with 30mpg, they have paper junk air filters… our CL’s get 6MPG’s better because we run “K&N” like filters” :rofl
