i need help please
 

ok so i have a b18c5 it comes stock with ngk 5555 plugs(platinum plug).but i am running a 55 wet shot right now and am planning on putting it to a 75 shot. well it is highly recommended not to use platinum spark plugs with nitrous. well i know i need to go with a colder plug. my question is, what plug do i go with? it is a 99 civic coupe b18c5 swap with i/e and nitrous i have been told that you should run iridium plugs that noone has had any problems with them so far. anyone have any suggestions?

RE: i need help please
 

ZEX actually makes plugs specifically for nitrous setups. For a 55 shot Id go one step colder than stock.

RE: i need help please
 

thank you polo for replying but i know i need to go colder but i dont know which plugs to buy.
i want to stay with NGK. i was recommended by someone to use BKR7EIX11 would this plug work?

RE: i need help please
 

Yes, the BKR7EIX11 will work.

I have plenty of friends running iridium plugs with their nitrous setups.
