canadian eh? so what plugs should I buy? Iridium or copper? any others. I guess what works best? I took the intake off my Aveo and was shocked to see the metalcorrugated aluminium tube coming off it that attaches to the EGR valve almost totally closed off with crap! the intake butterfly too. I actually took a flathead screwdriver and chunked off all the big stuff, then brakleened the rest. looks new now. I'd recommend checking your intake and spare no xpense on air filters. q.
