Description:

This is a tried and proven AWESOME upgrade I'd discovered for our cars a few years back and it has become one of the goto mods , aftermarket companies are actually starting to copy me and list them as an r53 enlarged throttlebody for much more $$$. You get a massive amount of more flow AND I personally gained 2psi more max( i made 17psi through my grs motorsport ic but i made 19psi through the stock ic ). Some gain more some gain less. All depends on your setup.
I'm in need of some money at the moment so I went back to stock in the meantime to try and clear a few bucks for a replacement hood.
Everything was used 5x months and maybe 2000miles IF that. 
I'm including a bmw 65mm throttlebody TAPPED so you can run stock vacuum routing , CUSTOM made FULL 3in intake that clears everything and fits the tbody perfectly (i have a manufacturer special make these specifically to fit this throttlebody) , also an electronic throttle controller already customized to plug RITE IN and it allows you to fine tune the throttle input because it WILL be different with a larger tbody ( less input give you more air n speed so it can become touchy without the controller) and I'm including a bracket that fits the throttlebody perfectly too so your boost tube will continue to stay in place firmly. 
250$ + shipping FOR EVERYTHING.  pm or respond to this post.

stay safe N motor on !!!!
