i know the 2 stage colder number for the MY00-01, not sure for your car. And yes they are right you need to run 2 stages colder to prevent detonation or pre-ignition.

Sup,

What spark plugs should I get for my 2000 Impreza RS running on a ZEX kit? Do you know the part number?

your car has some serious issues if you have detonation for the few seconds your on the bottle. most people on this bord don't have the nut's to run more the a 55 shot with a zex kit! it sounds like you need more fuel pressuer or higher octane gas. check your plugs to see if they are white! don't use octane booster! some aftermarket chips will pull back your timing! one step colder is ok but you should not need it for less that 80 hp shot. check the zex brain! there might be teflon tape or past cloging a mesh filter inside a solenoide?
I'm going to run a 100 shot with 25% tulene and 93 octane pump gas, i don't think i will need it! but it runs are all track with greddy TDO6-SH (20g) @ 18 psi with stock fuel system.

Don't listen to who ever told you to run 2 stages colder! That would be an NGK 8 plug! That is way to cold since you are only going ot be on the bottle for short bursts and not on the bottle most of the time. Personally, when I ran with just nitrous (before the turbo) I rna the NGK 6's which is a stock het range plug. You can either do that or go with the NGK 7's but do not go with 8's. you will fowl them or something.

And remember, NGK numbers (6,7,8) are backwards from most spark plug companies where the lower the number (with most companies), the colder the plug.
