So I got the GTP last month and haven't done anything to it yet. I am going to do some routine maintainence first and get the car running the best that it can in stock configuration before doing any mods so that I can actually tell if the mods do anything.
Mainly o2's, plugs and wires and synthetic oil.
Calling around, I cannot believe the prices!!!! O2's for $100 a piece?? Plugs, $40?? And I need to do the front and rear brakes...$140???

Seriously, are those prices the norm? Oh, and what plugs should I use?? Everything is stock except for a CAI. I will be adding a d/p and crossover. Won't be doing the pulley for a while still.

plugs should be like $10
Front O2 should be like $60-70
Rear o2 sim is like $30
Are you just doing the brake pads?

I use autolite plugs

OEM plugs are $6 each. O2 is around $60, unless you search for cheaper. Brakes go from $20/set on up, depending on brand and grade. Rotors around $20/each.

Autolite 605's will be fine for your setup, they are at most $2 apiece. O2 sensor for me was $74.99

The last time I bought spark plugs(AC Delco Iridiums), one place sold them for $15.60 each! I found them elsewhere for less than half of that. For $15.60 per plug, a mechanic had better jump out of the box and install them for me...

I got my AL's for 12 bucks. Why are your plugs so expensive?

ALs are among the cheapest plugs available. $1.49 each at work for the coppers.

platinums and irridiums are on the pricey side.

O reilly price for Bosch 02 sensors are 63.xx rear and 68.xx for front, OEM sensors are right around 100 bucks each, but that's GM. and 140 for all four corners on brakes isn't that bad, I'vr seen a lot worse

There's a reason dealerships are called 'stealerships'.

I got my O2 for around 70. 140 for brakes is nothing .. Take the chance to upgrade.

40 for plugs made me laugh. Thanks, I needed it.
