They would probably benefit more than Civics with 1.6 or 1.5 L. Really the relevant parameter is the flow rate of air into the engine, which is a function of RPM and displacement. Since the K20 is a higher rev engine than the Accord or CR-V engine, so it would see more benefits. Subaru's, for instance, are 2.5 L and they see up to 15 HP from intake and exhaust alone, and most V8's see pretty large power gains from exhaust mods as well.
