I have a B16a that I am going to spray nitrous on and am unsure of what kind of spark plugs to get. I was told to get colder plugs. I have already retarded my timing. If any body could help me out with a part number or something along thoose lines I would graetly appreciate it.

 

Plugs to run for juice is NGK 9. Its a race plug only. You can't buy these at any autozone or kragen. I have box at home. I will post up the part number for you later on.

 

NGK-5820

Summit Racing part #. They work fine 4 me!

 

nissan maxima spark plugs, cant remember what year. like 90 or 95

 

if you're spraying, why not use zex sparkplugs?

 

cuz they are ****! the ceramic melted and cracked and ruined my bro's head on his motor when he used them. they are the worst spark plugs you cant buy

 

Well I just got a chipped ECU that retards my timing by 3 degrees. Is there anything else I would need to do for a 55 shot. I was told I wouldnt need colder spark plugs if my timing is retarded. Could just go with stock plugs?

 

Get Denso Irridium Spark Plugs and go one step colder. Those spark plugs last longer than platinum with even better performance that silver electrode spark plugs.

 

The Plugs to use are Stock No. 5238 Sn. R5671A-9

The Plug Should only have a 9 on it.
