as i am looking to upgrade to a direct port wet kit from a dry(which requires me to r&r my fuel rail to get a -4 end welded on to supply the fuel solenoid)i was looking for anyone that has run this new vibrant performance sheet metal intake on their n/a mazda 3,and if so,how do you like it vs. the stock manifold with the butterflies internal to boost low end torque and open up at w.o.t. to boost high end power.anyone running this sheet metal setup?did mielage suffer,how's the driveability.anyone but myself dream this idea up?i would direct port the stock manifold,however those internal butterflies controlled by the 2 vacuum solenoids are in my way.thanks
