I have a 2.2 as well and most everything engine wise that goes on a '97 accord will fit the '97 CL..

Intake, exhaust, springs/coilovers, system, wheels, clear turnsignals, re-do the grill, Wings West front lip, spoiler, HIDs,

If he's interested in a car forum about CLs tell him to go to : www.acl.com
