^ agreed,
My stock air boxes with drop ins and PMAFS ran great, I did the mod below also.
I did not really want to drop 500 bucks on intakes but do like the G3's, they do seem to perform, I ran this set up for less then 200 bucks, COBB post MAF, stock MAF tubes, some silicon elbows, and a couple AEM dry flow filters, I tuned the fuel via a COBB AP and WBo2, it made for a great little responsive Z with a set of test pipes.
