If you look at the VOLANT intake system it's still getting AIR to your motor from that small stock hole. The K&N is useing the stock hole and getting fresh AIR from the bottom of the truck. Also the inlet tube of the K&N looks bigger and that kit may give you MORE POWER!!!! remember more air more POWER!!!!!! :thumbup: CHECK THIS OUTMcBride2k1 said:Is there any noticeable difference between these two power wise.
