Can a air filter cause the engine to lose power?

Answer

If it is dirty and clogged. almost all air cleaners cause a power loss. K & N and other brands make "highh flow" filters and these still cause a restriction, but most engines are calibrated to accept the filter restriction. if your filter is dirty, clean it or better yet, buy a new one. they are very cheap and improve performance as well as gas milage. whatever you do DONT run an engine without one!
