i fond on ebay $135 intake system for my ssei and somewhere else for $200, anyone know of cheaper intakes with the tube and filter ready to go? what do i all need to change the coil packs, wires, plugs and all that and how much did that cost you all?

There are about 50 topics in Performance on intakes. Read them, and Techinfo.

Plugs and wires won't get you any performance, other than what you lost when they 'went bad'. Coils are pretty much in the same boat other than maybe 5 hp midrange. If they're not bad, don't change them. These are tuneup items, not power-adders.

For $200 you can get a high-flow carsound or Magnaflow 2.5" cat (ebay), home made CAI, and remove your exhaust resonator. You will have about 10-20 hp gain with all these mods given the rest of your drivetrain is running right. Also remind your dad not to put absolutely anything under 91 octane in when these mods are in.

That'* the kicker right there (as far as price goes). I need to be able to justify an extra $3-4 per gallon of gas, which will add up to a lot more than the initial cost of the mods! Sometimes I hate being so cheap...

With intake and exhaust on a NA, 87 octane is fine. You may have to go up to mid-grade after chipping (89 octane).
