Im wondering what are the very best spark plugs to use? This may sound like a dumb question but how do you change them?

Under that cover on the top of your engine. NGK BKR7E ftw

changing them is pretty simple for a first timer. first you want to make sure they're gapped properly (you can buy an "expensive" gap tool from any auto parts store for less than 5 dollars.) to get to the plugs, you take off the 4 (i think, going from memory) STAR bolts on top of the engine, pull the cover off. it's a T-something bit, pretty standard in any tool set. start from the left, you'll see that there's a bolt holding in a sensor. take that bolt off, pull the boot out. it's a good idea to use some compressed air so you don't drop dirt in the cylinder head. then stick your extension and socket in, unscrew it, and pull it out. If you don't have a spark plug socket, (it has rubber inside to hold the plug) you can use an extendable magnet pole. i bought a good one for about 3 dollars. then it's as simple as putting the new one in, tightening it, putting the boot back in, move on to the next one. i changed mine in about 15 minutes, but i've done them before so i wasn't figuring it out as i went.

a couple things to make sure you do:

1) do NOT just drop the plug in. that will mess up the gap or damage the plug and they won't work properly
2) do not overtighten. they should be pretty snug, but not so tight that you're twisting with all your force. if you snap one in the cylinder head, have fun literally taking your engine apart to get it out.
3) if the plug doesn't go, DON'T force it. tighten it by hand, loosely untill it starts to thread properly. once it's hand tight (literally using your hand to twist the extension) then attacth the wrench and finish up.
4) make sure the car is completely cool. in the morning before you drive at all is the ideal time. after driving, the engine may be cool to the touch, but the inside is probably still hot unless you wait a few hours.

after you're done changine the plugs, start the car, and see how it feels. if it feels good, then you're done. if not, adjust the gap and try again. if you do have to adjust the gap, refer to #4!

Where do you get the NGK's from in Canada? Can you get them from Canadian tire?

NGK BKR7E I just put them in about a week ago seem to work well. Helped with the stage 2 hiccups.

Get some anti sieze and dab some onto the threads. Cheap insurance to keep them from getting locked in the head.

ok so what plugs to run if there not agreeing with you. i had bkr7e's in mine for bout 4k and they were fouled out BAD, anything thing over 15% throttle it sputtered, so i went with the bkr6e's well i have maybe 200 miles on them and ive noticed when i got on it the other day about 5500 rpm it had slight hesitation to it. and everyone i know is saying close the gap, but there at .032 which should be fine, for 18lbs of boost.
