what bout on the s14 sr im running 12 pounds what would be better
NGK
BCPR7ES
BKR7E
BKR7EIX
i mostly care about the power that i will get out of them because i change them out frequently
I would highly recommend running the iridium core BKR7eix Spark plugs, great for a lightly modified SR20det and they will work better/last much longer than the copper core BKR7e spark plugs.
Here is a nice article that really breaks down all the different
NGK SR20det Spark plugs
I have used BKR6e, BKR7e, BKR7eix, BKR8eix and BKR9eix in SR20's over the years depending on power/fuel type. 95% of SR20det's with basic mods should be using the
BKR7eix spark plugs. (1 step colder iridium core NGK plugs)
