I have a dry nos system on my R. It's set-up as antilag, so it comes on between 2-4K revs which is controlled by the unichip.

I was just wondering what the best spark plugs were to use with nos.

(ps. the unichip will be for sale soon, and its only 1 month old (3 yrs warranty) and its the newer smaller one which can do launch control etc.)

I saw a thread a while back saying hks irdiums wern't great with nos for some reason or other, but i cant find it.

Your help would be appreciated.

Cheers.

James.

NEVER USE PLATINUMS WITH NITROUS!!!!!

I dont know how they react to iridiums but regular copper plugs are best with it.

The standard plag is NGK's BKR7E depending on the boost you are running you may be using BKR8E. Rule of thumb is go 1 heat range colder per 100hp shot.

Stock boost and 50bhp shot or less stick with the NGK BKR7E
Higher boost and/or higher bhp nitrous shot go with BKR8E

It is set up as 1.4 on low boost and 1.7 on high boost and its a 50bhp shot.
