y would u cut a whole in the head shield? heat shields are useful for SRI and they help u sometimes skip a potential defect if the copper cant directly see the pod he'll think nothing of it, u have an automatic civic, u have no real power as it is, and only advanatge of CAI as oppose to SRI is its SLIGHT SLIGHT power increase, i reckn no point, just get a normal SRI (which'll sound MUCH better aswell) and leave the heat shield on, no point cutting a hole which will only be effective once in a blue moon...
