I recall seeing a story in honda tuning couple years ago where a guy with a D16Z6 had his IM extruded and he got a little increase in mpg along with a bump in trq/hp as this smoothed the airflow alot. anybody interested in having their VX Intake Manifold extrude honed? Their site says 15-20% discount on group buys of at least 4 same parts(time saved for them to change their equipment).

Maybe having it port matched first will help ? let me know what u guys think. ive mostly though along the lines of PnP for hp/trq but now im thinking along power/fuel efficiency*spell check*. Last time i checked they charged $395 to extrude Intake/Exhaust manifolds.
