    Features

    • The Powr-Flo spacers' bore is designed to increase the velocity of the air flow into the intake manifold. By delivering the air with more velocity it allows more air into the combustion chamber for a denser air charge. The design results in improved throttle response and impressive power gains in the mid range and top end.

    5.0 Well worth the $

    Very simple installation on my '08 Silverado 4.3 that's been a pig since day 1. It probably took less than 10 minutes to install. I instantly have much better throttle response and power. After 2 weeks my MPG is better (about +2mpg) and may get even better if I can keep my foot out of it.

    4.0 Great product!!!

    I put this on my 2010 Nissan Titan. Great product! engine idled a little fast & rough for the first day or so, but then smoothed out. Didn't notice any immediate gains, but after about a week or two, I have seen my gas mileage increase by 1.8 MPG. That may not sound like much, but it was getting 12.9 MPG and now it is a consistent 14.7 and I am driving just as I as before. That an extra 45 miles per tankful. Instructions were vague and there are no markings for which way airflow should go, so I just went by which way the sticker was facing. Easy to install. Does whistle slightly, but only noticed it with windows down, sitting still revving the engine and then you still have to try to hear it. Not bad at all.

    3.0 hard to notice

    very easy to install, improved fuel economy, but the whistling sound is annoying at times.

    Q: Does this require fuel system modification (bigger injectors, more pressure etc) How much of a power gain can I expect on a 2009 Ford ranger Answer this question

    A: No other mods needed. This is a direct replacement of stock throttle body. This one is for GM applications, will not fit your Ranger.

    Q: can i put this with my original stock filter? or do i have to buy a k&n filter to install this part? Answer this question
