hey zonker, there is a better way to increase ignition timing. Add some resistance to your IAT and the comp will think it is colder. It will add timing to compensate.
Other than that, it really doesn't matter what TYPE of intake you run. The only thing that matters is to make sure there is a little restriction to intake flow as possible. Measuring pressure throughout the intake and making sure it is as close to even thru the whole system is what matters.
