20vAFM (silvertop) vs. 20vMAP (blacktop) plenum
It is said that increasing the size of the intake surge tank will help increase performance somewhat as seen in magazines, therefore Zul thought of comparing the two generic and found the 20vMAP version lager by a significant amount. He has made the conversion and claim performance increase. However no dyno test were made, perhaps in the future.
