A few words of advice:

1) Make sure you use copper plugs. Gap aggressively so you can get a large spark. Change them often.



uhm, not to put RCR down, just info, be very careful about gapping. larger gap is often a bad idea. nitrous creates mega cyl pressures. and if the gap is extreme the spark wont jump the gap, if this happens at 8 or 9 k, you could fill the cylinder with 6 or 8 charges of giggle gas, and when it does spark again, BANG. something will give. trust me, ive had many nitrous backfires, and seen many big motors taken down do to lilttle stuff such as gap. be careful with that single nozzle setup. your prone to pooling. anyways, spray away man, and have fun.. dave

 

yes, i've been told by other s2k nitrous users that gapping them to stock or a little smaller is a better way to go.. i went with a stock gap to test things out...

 

When I said gap agressively, I meant small gap. Sorry for confusion. I use .32 on my NGK racing plugs.

The larger spark is from the copper racing plugs. Iridium and plantinum sparks are very small compared to copper.

Also go 1 or 2 steps colder. They foul easier, so you need to change them at least once a month. Luckily, they're pretty cheap. Only about $1.50 each.
