View Full Version : Spark Plug Preference

04-24-2006, 04:32 PM
Any preference on new plugs for a 2001 Cobra. I have been looking for NGK TR6's on their website but it doesnt look like they are offered. Does anyone know if they will work.

Its a toss up between the NGK TR6 iridium, denso's, or brisks? I was thinking about an extra set of plugs for nitrous (about 100hp jets) about two steps colder.

Any suggestions, thanks guys.

My 1999 SVT manual supplement says there are 2 types of plugs in a set, one type for 4 specific cly's and another type for the other 4:dunno:

I just posted here but poof. it disappeared. oh well.

If you are looking for a colder plug, look for the 03 NGK TR6 plug which is 2 heat ranges colder than the stock 01 plug. Wait and see what others respond with. Just remember one thing that the coil packs are sensitve to colder plugs and may not respond properly.
