colder plugs for ix
colder plugs for ix
what's an alternative to the NGK R7437-8 spark plug? I'm really not trying to pay 40 bucks a plug to run a colder plug. Again this is for an evo ix.
No I haven't ever ran colder plugs but I know I'm gonna need them for the next time I get tuned. So they won't be going in for a little; I just wanted to know what to buy
The reason I'm asking is I went both routes, never gonna consider going colder unless I well past 500whp.
