its all how you match up the intakes. iirc the 3400 upper intake flows better than the 3500 upper intake but the 3500 lower intake outflows the 3400 intake. you know just kicking **** in a bucket here but you have a turbo car. dont you want the air/fuel getting through your motor the quickest way possible? if not then you dont wanna run 10s. cause its not gonna happen on a stock 3.1 intake thats for sure
