spark plug

[connorling]

hey everyone, last weekend i pull out the plugs to have a quick look, it has some kind of white deposit on top, look on the net, it says "too hot"

suggested to use a higher cold range plug, the standard plug is level 6. so should i go for 7???

it is for the JDM b18c VtiR


it is very hard to find level7 plug, anyone know what plug i should use?? thanks

NGK BKR7EIX-11 for ITRs in general.. B16's use NGK BKR6EIX-11

well the above part numbers are iridiums but you get the drift...

NGK BKR7EIX-11 and NGK BKR6EIX-11 are basicly the same, only difference is the heat range, 6 is colder than 5, hence, it can takes higher heat=> for higher mod car(base on the NGK web site)

stupid AutoOne telling me the other way around, 5 is colder than 6, what a full of crap

lucky didn't order it

One manufacturer uses numbers going up, another uses numbers going down to indicate colder plugs.

Don't blame the AutoOne guys for that mess.

Can't remember who uses what.
