I see I see, is this partly because it's an older car too? Because I've seen induction kits placed in 1.3 Ford Ka's which are, granted, newer than my car but wouldn't the effect of having for example, a pipercross induction kit, have the same robbing effect as the civic? Seems silly to even try haha

.
Also you mentiioned sound, would the panel filter trigger any sort of change in sound (volume or otherwise) in my car?
