A filter, is a filter no matter what engine it is on....the difference is and what the test is pointing out, is the false, misleading information the aftermarket puts out about their "after-market filters & performance gains".
Let's take something very, very simple, the 5.4 gas engine. The 5.4 V8 for example if close to stock can only suck in a maximum of 480 cfm (a little thing called physics) and a flat panel filter will flow 500 cfm, there is simply no way any CAI on a relatively stock engine can increase the air flow into the engine, sure their filters may flow up to 900 cfm...so what- the engine simply will not inhale any more than that without forced induction or cam/valve changes (substantial).
