Definitely more power (not sure hp or torque) but, the engine gives more hmmp! feels more than 10 - 30 hp increase... when the gas pedal is pushed. Installation was not as easy as some others stated...took me way more than 1 hr...may be I am not as handy as others...But, overall, I definitely recommend to others as small upgrade..
