I have recently been deciding wether or not to install a cold air intake in my 2001 3.4L Tacoma. I have seen a few Tacomas with cold air intakes installed and I must admit-- they sound really good. From what i've researched, these "cold air intakes" actually will suck warmer air into the engine as opposed to the stock intake (which draws air from the fender.) If I were to install a cold air intake would there be a noticeable loss in performance? Or would the installation of an after market intake increase my HP?
