okay so here is what im wondering. i've found a mac tb for 160, and ive seen like a fc for like 250. i was wondering if there is a difference in performance between the mac and the fc? also, i found a mac cold air intake for 130, but i've been told that intake makes a difference, so the more you pay the more you get. so i was wondering if i should get the mac tb and save up and get a good intake or get the mac intake and save up for the tb? also if i don't have intake will a k&n fliter make a difference?(i'm also putting in exhaust and and an udp) thanks.
