mr smith, looks perfect. Instant power for polini.

If by huge difference you mean better everything, then yes, opening the intake does make a huge difference. I can't talk for zachlee, but I just opened the intake, didn't raise anything. Better midrange for sure.

Don't be scared, just bust out the dremmel and go wild. Only way you can really mess up is by lowering the exhaust or raising the intake too far. I thought my exhaust was too big, but turned out it made it way better.
