What's Colder ?
Was running these in my VW 2.0 with the timing maxxed out & high octane, still needed a step colder. I called Autolite 855.200.5200 & spoke with Marty. He told me going colder from AR3910, in order would be AR3932 & AR3931. 31 is the coldest plug they make in this configuration - thread size, wrench size etc. AR3933 is the same heat range as 3910 but without the extended tip that the 3911 & 3910 have. In this note, 3911 is hotter than 3910. 33,32,&31 all have standard tip, not extended. Marty sounds like he's been there since day one. He's got the knowledge & answers & was happy to take my call. Hope this helps.
