Help w/ sparkplug heat index range
Help w/ sparkplug heat index range
Hey guys, I'm pretty sure that I need new spark plugs and I am curious as to what heat index range I should get. I plan on getting the HKS iridium plugs. My mods are in my sig, and it is my daily driver. Sometimes I push her hard, and sometimes I just cruise. Any help would be appreciated.
I love it, two new posts today on exactly the same subject on the front page.
