Spark Plugs

[pnyxprs96]

Ok so i read a artical some where about the heat ranges of spark plugs and it was saying something about going one heat range colder from the tr32 to 22 for a NA car. I was wonder what u guys thought and what is the best plug to use. thanks in advance

The only plug i will use is the NGK plug.

No need to go a colder heat range for a N/A car. That is procedure for basic nitrous and forced induction cars.

are you stock? if so, use the Motorcraft plug for your application.

btw stock meaning no supercharger, turbocharger or nitrous.
