1) I've had autozone parts last longer than name-brand OEM parts
2) Those longer lasting parts also came with warranties
3) Autozone sells NGK
4) Autozone FTMFW ;)

agreed. i went through 20 sets of 'toyota' wipers....and kept doin the parts warranty thing...well they stopped the parts warranty. so i shopped around. michillin, annco, bosch, rainX, and all sorts of other brands of inserts and whole blades. always streaking on the first swipe and never lasted more than a month. bought a set from autozone, the 'duralals' wipers for 12 bux a set....works perfect and going on 6 months now.

also, as long as you're not getting the cheapo, bottom tier stuff like brake pads or rotors, you can expect better than stock performance out of them. i like mid-grade or better myself when it comes to pads, and top tier when it comes to rotors. as for plugs and wires....they're all basically the same. but i'll never use bosch, and i wouldnt put champion in my lawn mower. other than that...delco, ngk, auto-lite...whatever's better in your opinion.

a lot of times what happens is when a patent runs out everyon and their mother will mimic that patent and make just as high a quality part as the big guys. the parts use the same materials, the same processing, and in more cases than not...the same plant and distributors/packaging companies. do some research on your companies. if you're in the grocery store check the labels. market basket uses 'parade' brand and if you look on there it's packaged in the same plants as KRAFT, oscar myer, McKormick, Betty Crocker and all the other name brands...and that means the same product.

The first thing I did was swap out the spark plugs when I got the car. I had original oems and replaced them with the new iridium fusion (platnium) plugs. Need the iridium because without it, they get to hot. They run great, the idle is smoother, I haven't had any problems and I got 4k on them now. There was a sale a while back so you got 2 bucks off each plug. I'll check them later but I doubt there will be and problems.
