spark plugs and wires?? Get the cheapest bosche spark plug you can get, like $1.70. Because seriously, those plugs that are $7 are a extreme waste of money. As for wires... unless your running one of those plasma boosters, you dont need a set of 8mm silicone wires. $180 for a set is rediculous. Go get the OEM ones from a dealer or some place online.

Not looking for anything high performance. This is just my daily driver, and I bought it about 2-3 months ago. I'm not sure when the last tune up was done prior to me buying it, so I just wanted to take care of it soon.

i beg to differ.

at least in M3, it makes a difference.

i had changed to bosch long before that thread ever appeared and noticed a performance loss. when that thread appeared, it only confirmed my observation. i am switching back to ngk with QUP designation.

(edit)
oops, to answer the original question, this place has pretty competetive prices for plugs. i don't know about wires though:
