I have the SS inductions throttle body on my ute.. I didnt notice anything... I also bought the SS inductions intake, a underdriver balancer, ford flasher... then later on I bought the SS inductions Growler (I noticed more from the growler).. I then reinstalled the SS inductions intake and joined it up to the growler with a custom pipe (for more air)... but I personally reckon extractors, exhaust and growler is what you would notice the most.... I finally gave up on the N/A idea and have just purchased a CAPA Supercharger kit lol I would honestly advise you think about it... because if you decide to turbo or supercharge it later on.. you would have wasted all the money on the intakes, extractors and exhaust (cause you may need to buy a bigger exhaust again to get the most power out of it)
