I was thinking about getting a CAI and doing the lunchbox delete, but just had a couple questions. Would reducing the exhaust restriction reduce some back pressure that is required by these small engine's valves to function properly? and how safe(waterwise) is it to put in a CAI? and what kind? I dont want to risk rain water getting in thru the intake, so what are the options?
