Welcome to the Club. As far as intake, I would go with the K&N since the SRT's chip is designed for use with the SRT intake. It won't compensate for other mods you make to the car. If you don't plan on going FI (forced induction) then go with an Apexi SAFC or Neo that way you can tune for other mods as you add them. Other performance mods you may want to look into are: LSD (limited-slip differential), TC (high stall speed torque converter), catback exhaust & headers. These mods should give you better performance but there's no substitute for FI.

I searched the K&N site and all that i could find is a filter. Do they make an actual intake? If i am planning on getting the borla exhaust and possibly headers do you think i am better off with the SRT or getting the Neo and some other intake. The only thing that worries me about the neo is that i have to set the fuel my self and i am sure i would manage to screw that up somehow

I would definitely not recommend you tune the SAFC yourself if you don't know what you're doing. You can get the SRT and just not install the chip. Like I said, you're better off not installing the chip because it's only going to take into account the intake and not the other mods you have done to the car. It's not like you're going to make insane power from bolt-on mods but you want to get the most out of your car.
