Can we use the Autolite HT0's even though they are a colder plug in these cars N/a?

I have heard most people use the HT1's but a shop told me all they use is the HT0's in both... they just don't gap the HT0's down like they do other plugs.


Any information on this?

By using a colder plug in a NA car you do run the risk of a plug fouling because they don't run hot enough to burn off deposits.

I talked to BlowbyRacing and HPP Racing and both said they use them in our NA cars.
HPP said that is all they used.

Blowby said they use both.. and that as long as you don't gap the HT0's that it will
be plenty hot enough to not worry about deposits.

They also said if you decide to go FI later then you don't have to worry about
changing the plugs.

They said they were fantastic plugs.

Bump for more input on this.
So far I have gotten pretty good responses but ONE person
told me he had them and he had a skip at the top end and replaced them with the HT1 and the skip went away.

How could it cause a skip unless the plug was actually BAD?

Ack I had them put in and I am having some skips/misses.
I guess it's back to the store to buy the HT1's!
