    My truck is a 2013 Tundra 4.6 Liter, I am installing a cold air intake on my truck. I was sold a Throttle body spacer. I have read not to use it on my truck, because the 4.6 already has what they call ACIS which already does what the spacer was designed to do. Is this true. Please help? Thanks for any helpp you can impart. GAH

    Metric shit ton of parts
    CAI and TB spacer are both a waste of money. No real performance gains, just a change in sound.

    Throttle bodies only work on carbureted engines. They do nothing on engines with Fuel Injection. Most vehicles already take in cold air (I know the Tacoma takes it from the right front wheel well.) so a CAI won't add much besides sound as Jason said.

    The only way to get strap on power is via Forced Induction (Turbo/Supercharger) or by manipulating the torque band. (Intake Manifold Spacer.)
