After using the search function (yay noob!

) I have learned that a cat back steals hp from the I5. Most people are pleased with the K&N air intake except it is louder, and most of what is available for H3 performance is snake oil. My questions:
1. Where to buy performance upgrades, who do you guys support?
2. Besides K&N, any other cold air intake kits?
3. Anybody make a power programmer (i.e. Hypertech)? My Hypertech on my Dodge truck bumped performance and allowed me to reset the speedo to 35" tires!
4. Any other suggested performance mods? I know that with each piece of bling I gain 1-2 hp!
