So im getting my rbc ported to 70mm with a bigger TB. But intakes such as injen and aem are only 65mm around and won't fit. I dont want to relocate my battery. Does anyone make one or know a way to go about making one to fit? I read that you want to have the manifold opening, TB and intake diameter to all match up for proper air flow. But how do I go about doing so?
