Unless you make other intake and exhaust mods, the results of this will be minimal and probably not worth it. But, when done in conjunction with a high flow intake and exhaust you will have great gains.
I have installed a KN full flow kit. I haven't touched the exhaust yet, any suggestions? I realize air in, needs air out, concept. I'm just trying to squeeze a few more MPGs out. What other mods would help?
throttle body spacers, worth it or not?
