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?

 

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

 

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?

 

Yes, the BKR7EIX11 will work.

 

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

 

what about these plugs?
