i know i need a colder plug for nitrous but whats everyone using? i have bosch 4's in there now

 

I would use the ngk bkr7e. The new NGK part #4644 And the old par number is #6097. Ive been running them forever, and no problems at all! Even On NA Low comp turbo motors with no turbo......lol They are $2.09 each at the napa local to me.

 

Whatever you do, get rid of those bosch plugs asap. Regular NGK BKR7E like mentioned would be fine.

 

the b16 came with platnum plugs stock though?

 

I've heard nitrous and platnum or irdium spark plugs is a no no, as there is some chemical reaction from the nitrous. regular cheap resistor type NGK copper plugs are the best, period. platnum plugs are for people who want to waist money
