I have the comp cams 127200 cams and a 100 shot with a bama file tune, what spark plugs would you recommend that I use...

We do not offer a ZEX plug for this application. I would call either Autolite or NGK's tech lines to get a part number from them. You need to drop down 1 heat range below factory.

Thank you,

I found the NGK application that is one step colder, note this is for the 08 1/2 and up Mustangs with the brown coil boots and open end plugs, NGK plug 7554 ZNAR7AIX - this is the one step colder plug...
