i ran ngk bcr8es at more than 200 bhp for along time. Nice n cheap and u can replace them anytime u want.
people will tell u of other ones that will help u spend more money.
The only downside of the bcr8es is the tip being recessed doesnt make for the best starting. ( Someone want to confirm that statement for me as its been a while since i thought about it. the evo came wih plugs that lasted 40k+ )
