Spark plug question

(1/1)

Ken4004:
Hi Everyone just a quick question about spark plugs on the 400 4 , in the Haines manual it calls for DR8ESL plugs I have DR8ES plugs does anyone know the difference ?

Bryanj:
Half a heat grade, they will be fine unless you are a nutter!

Ken4004:
Ok thanks for the info

I thought it should be D8EA or denso x24es

Also if you're running resistor plug caps you don't really want a resistor plug as well.
