How the hell do I get to them

 

Easy...become double lointed! LOL
The hard ones are the ones on the passenger side. Do one at a time, and take your time. I used a plug socket that has a universal joint on it. Wrap some electrical tape around the universal joint to stiffen it up. Also I used a short extension on a few. When you go to put one in, use a short length of either 5/16" or 3/8" fuel line. Insert the end of the plug in the line, and use it to start the plug. Also be sure to use a dab of Anti-Seize on the threads, and dielectric grease inside the plug wire boot.
I was luck in the fact I was also changing the throttle body at the same time, so I removed the CAI and T/B and it was a "little" easier to get the back 2 on the passenger side.
DO NOT...repeat DO NOT remove the wire from the plug by pulling on the the plug wire. Grab the plug wire BOOT and twist it to break it free from the plug and pull it off by the boot too. If you yank on the wire itself, you can REALLY easily break the wire.

 

wat are the benefits from replacing spark plugs and spark plug wires?

 

Umm..make the car run without a misfire. Wires degrade. They develop cross fire from cracked insolation. Plug electrodes degrade from sparking 50,000 volts.

 

ooo ic, any suggestion on how often they need to be replaced? i juss hit 30000 on a 04

 

Depends on the plug. Most platinum around 50-60 k miles. Standard plugs around 30 k, and Irridium, like the ones I put in my stang are rated for 90,000 miles. You have platinum from the factory, unless someone already replaced them.

 

o ic, i dont think previous owner replaced them so i should be good for another 30k miles

 

Well if the previous owner didn't touch them, then you may want to change those out and get some decent wires from http://www.autobages.com/ and be done with it. Now Harv on his 03 had platinum plugs on his car and had no problems that I know of, but every shop and store I went to around here, when I had a problem with my maf sensor, told me to stay away from platinums with a sixer, didn't ask why though, but every shop, store, etc, said that they aren't good for anything smaller than a V8 or anything without F/I, so make sure you check into this befor you buy plugs, me I just went with standard copper plugs, damn platinums, I still have those things in my room in a bag thinking that's what fed up my maf, but it wasn't, it was a short.[:@]

 

also better gas mileage and a much smoother idle with new plugs and wires

 

Actually, I went with the IrridiumX plugs. IMO, they are the best way too go.
