Default Spark Plug recommendations for running N20??

(NX Wet Kit 50 shot)
I remember reading it is highly recommended to change your spark plugs to ones with a colder setting/tolerance. I have no idea. If this is true though, can someone recommend which ones and any places (online would be great) to buy them. Thanks

In general, guys that have add-on turbo kits, run really high boost, or extremely high compression ratios will switch to a plug that is one step colder. This is done to combat pre-ignition and detonation.

If you want to go to one step colder.....just go to the parts store and aks them. Tell them what car you have now....they can look the plug up, and give you the next step colder.

The only issue I see with this is your normal daily driving without nitrous will suffer. The plugs will not reach their self cleaning temp, and will not ignite the a/f mix as well.

A better solution would be to get some sort of chip or something that limits timing when you hit the nitrous. This is simply another method to control pre-ignition and detonation.

Yes with nitrous you have to use colder plugs, almost all people use NGK BKR7E's I think the part # is 6097 try www.summitracing.com please look up the part number before buying

So are cooler spark plugs absolutely 100% a necessity, or would I be fine with the stock plugs?How drastically will "performance" suffer driving normally?? If I'm going to order these, should I go ahead and get new wires as well?? I recall people saying GC's don't really show a noticeable difference with new plugs and wires, but is it better off to go ahead and get them?

The ones at summit racing:
NGK-9825 Spark Plug Wires, Custom, 4Cyl. $21.99

yay or nay??

also I browsed through summit racing....did a search for NGK-6097 and all that came up was "spark plug..$1.99"...these the right ones???

As Andy said....most people who do nitrous run colder plugs......they do this because of what I mentioned earlier....and it's cheaper then some sort of timing/ignition module.

Just try the plugs and see what they do for your car. If you get serious problems.....you may need to look into some other option.

You just want the plugs, not the wires. I can find the exact part # you need. I'll post later today with the number. These will be the plug you need.

so the ones you mentioned above are not the correct ones??.....when i did a manufacturer # search using NGK BKR7E, it came up with the same thing as doing a part number search for 6097...with the spark plug 1.99.

NGK 7's should only be $1.99 from Summit... they're copper, not platinum so they'll be noticably cheaper.

you can also talk to the company your getting the kit from. they should have them or be able to get the plugs you need. Impreawd, Richie, got one degree colder plugs. and i think it has less to do with proformence loss as it does with damage to the engine. depending on how much of a shot your going to be running will be the deciding factor on how much colder you will want to go.

yes those are the same ones. Sorry about not replying. Those NGK's are great plugs I suggest buying 8 instead of 4 so you have extras.
