Thanks, btw the windshield trim isnt put in officially yet, its just there to see how it looks, i still need a new windshield, and the ppl putting the new glass in said they'll put the trim on for free too! But to answer your question, yes i did notice a spike in throttle increase, now when i floor the gas pedal, the engine shows more response than when i was using the stock airbox. BTW im running stock exhaust, completely stock...
