NGK od. Autolite

[SchwarzStock]

In the past I have always had the best results with Autolite spark plugs. Currently I have NGK's but I am not very happy with the way the car is running, I think the plugs may be too cold. With the Autolites I was always able to increase or decrease the heat range to my car. I don't know anything about the NGK possibilities, any recommendations for a 302 with Aluminum heads?

No idea regarding the aluminum heads, but I only use Autolite platinums. Never had any issues with them.

Hi,
I drive aluminum heads with NGK sparks in a 302 and have no problems with it.

I just bought a set of "5"'s. Had to go to two shops, they never have 8 plugs.....
