What are some good intake systems for the 4.8L other than the K&N and are there any superchargers that will not void factory waranty?

Superchargers dont void your waranty but any damage as a direct result of the supercharger would not be covered.
The Radix Magnacharger is a complete kit and they waranty engine and driveline (correct me if I'm wrong) if you use the stock pulley and tuner and don't alter it.

same here on the radix

some intake companies are, outlaw, volant, aem, fram, GMPP, k&n, airraid, etc.

fyi the radix comes with a dropin K&N filter for your stock airbox and comes with a new high flow tube as part of the supercharger induction

What about a programer for the 07s is superchip the best one and how much will it realy improve power?
