Well there has been about 100 posts on all of your issues. But i will give you a quick breakdown. There is no point in adding ram intakes, unless you plan on modifying the intake into the manifold to bypass the current air filter boxes. Also with the rams you will be pulling hot air, even if you remove the existing covers behind the grille. Now there hasn't been any legit test saying this hurts or helps. But it definitely breaths hotter air. But it might look better. As far as the K&N filters get them, and keep your stock cold air intake. And for the cupholder. Either don't press it (lay your arm on it), you can change it out to the storage holder. Basically a hole in the console you put stuff in, but then you lose your only cup holder. And for other performance parts, The first thing i would say buy are K&N filters, Sprint Booster, than maybe a new pulley. Not too much need ot re-tune your ECM unless you plan on doing some other engine mods.
