Question by itzmenmeoly……: does fixing a high flow air filter improve fuel efficiency?
i have an alto. i plan to replace the stock air filter with a performance high flow filter by K&N. how would this affect my overall fuel efficiency? i often drive at economy speeds and seldom do some burnouts and high revvs.
