    3" vs 4" air intake

    Have question regarding air intake, maybe someone could help. I'm currently running a 3" air intake, but was wondering if I would benifit from a 4" intake. If so, would I notice the difference and why? The 3" is already larger than the mouth of the sc is'nt it? Any input would be greatly appreciated

    Look up Danny's tested flow results. If I remember the best was riva rear air then the 4" kana flex. To run the 4" there's a 3"-4" adapter
