I have NOS 5124 with a 70 shot. I know that there are copper plugs and platinum. What are the pros/cons between them? How many miles do they last? How do I know that they are used up and I need new ones? Where to buy the recommended plugs?

For the nitrous kit, is the fuel hose a larger, thicker hose to be tapped or the other way around?
2000 GXE 5 speed

 

Copper plugs are for nitrous/boosted....

You can't use platinum...

Plat - 60k Copper - 30k

You need 2 steps colder for 70 shot

I have 6 NGK Copper 2 step colder BKR7E-11 Spark plugs for $20 if ur interested

 

I dont think he needs 2 step colder plugs for 70 shot, for a 100+ shot he would need 2 step colder plugs. I am going to use one step colder plugs for my wet kit running 50-75 shot.

 

1 step per 50...

NX recommends 2 steps no matter what you get, NOS recommends 1 per 50

 

I run BKR7E's (2 steps colder) all the time even N/A.

 

Do I really need 2 step colder for a 75 shot?

 

uh yes....

 

what's the heat range on our plugs? i'm also wanting to install 1-step colder plugs for my 50 shot...

 

How much N/A hp does a 1-step colder plug sacrifice??
