Does anyone know if the ZEX Hyperformance plugs are 1 or 2 stages colder than stock?

I already have a set, but I probably don't want to run them if they're 2 stages colder.

Thanks

 

well what are your mods? I have them with my stage 2 and they work great, best plug by far I have ever used on the cobalt, and I have have 3 different sets of BKR7E's at different gaps. I run pulley sizes from the stage 2 pulley (3.07") down to 2.8" and it works great for all. I highly recommend them

 

Yeah, I ended up ditching the ZEX plugs as well. Regular BKR7E's gapped at .035 works great for me with my mods.
