    cheapest is always the K&N airfilter...otherwise, just search the 4.9 section for horsepower or something similar...there have been quite a few threads on it...good luck!!

    if you want replace all the factory parts with racing parts on the engine...and maybe look for a racing exhaust system that will increase hp.
