I got these plugs from lancer shop, and they said that they were one step colder than stock plugs. http://www.lancershop.com/customer/p...5&cat=8&page=1

Can anyone confirm that they are one step colder, because I was thinking that they were not.

 

i believe the "8's" are a step colder. i might be wrong.

 

if the stock ones are 6...then 7 would be colder.

 

Actually I was under the impression any plug with the same # in it was the same temp. So our stock plugs are IGR7A-G, so then wouldn't BPR7IEX or BPR7ES be the same as stock temp and not one step colder? I have been wondering for a while!
