sorry to highjack but are these good with nitrous?
well, the big thing is the heat range and how susceptible they are to the electrode breaking off. If you are running a 35 shot you can get away with stock heat range plugs and stock timing, but any bigger shot and you might run into detonation. If you go with a bigger shot you will want to run 1-2 step colder plugs and possibly pull some timing. Plus if you run into detonation you will want to replace your plugs. $10 copper NGK BKR plugs are ultimately the way to go, they will give you the same performance as your super duper high tech irridium plugs with the only exception of a 15-20k lifespan.
sorry i didnt get a clear answer. ill give more backround info
i have denso irridioms
i dont have nitrous, yet
this summer i plan to get a 75 wet shot
a few weeks after, i plan on getting a new Mallory Hyfire ignition and a used VAFC, ( i sold mine) and get it all dyno tuned.
is anything wrong with this? do i HAVE to install all this at once?
You will need new plugs no matter what if you plan on running a 75 shot. You will want atleast 1 step colder plugs and pull some timing or 2 step colder plugs and run the stock timing. You don't need to install everything at once, you can run a 75 shot just fine on the stock ignition with 2 step colder plugs (though you will always want to check your plugs after every spray on your first bottle and after that check your plugs if you squeeze longer than 5 seconds or so).
Originally posted by madshoe87 sorry I'm confused. These someone mentioned before, NGK BKR7E plugs, are these two steps or one step colder?
Any drawbacks from running two step colder plugs?
you will lose a little performance off the bottle, but it is necessary to have colder plugs and/or retarded timing. If you do not do so then you will have some good ol' detonation going on.

so I paid $54 for some damn plugs that I have to replace in a few months? I thought denso irridioms were on the top of the line with a few others? arent they colder? sorry I am new to this and trying to understand so I dont **** up w/ my nitrous.
get us the exact part number of the plugs and someone can probably cross reference it over. If your new Irridium plugs were just replacements for stock plugs then they will probably be too hot for anything over a 35 shot. They aren't bad plugs by any means, but the specs don't mix well with nitrous.
I would highly recommend running some NGK BRK7E plugs (these are one step colder than stock and are copper plugs) or possibly even one step colder than that depending on how much you are going to spray.
