intake comparison

so I know that K&N makes a great intake(argueably the best) but I'm wondering if this intake would match up to it when used in a 91 rx-7 non-turbo http://www.racingbeat.com/FRmazda2.htm I plan on getting headers, cat replacment pipe with presilencer, y-pipe (all these from racing beats) and the hi-power exhaust (HKS)
