How long does it usually take to change spark plugs?

Also, Is it important to do it on a cold engine (just curious)?

Why is it important to change the plug when doing the stage two?   Also when should you change out the orginal plugs? I got almost 20 thousand miles on my car will be doing the stage two with VMP and C&R Shelby dual fan heat exchanger alony with the Ford raceing damper. Hope to see around 540 to555 RWH with this mod.

colder range plugs help to keep detonation at bay....adding boost pressure and intake heat can cause detonation.

I bet you will see closer to 600 with the above listed mods...keep us posted!

I get terrible plug life from my NGK TR6s, about 3000 miles, and then the car will misfire under heavy load like 4th gear at the track.  I make more power than most GT500s, but not that much more.  

One of the FRPP engineers I know that works on the CJ is using one step colder platinum motorcraft plugs in the new and old CJ, AGSF-12FM1 plugs gapped at 0.035", I'm going to try those next.

If you are only upping the boost to 12-13psi with an upper pulley, IMO, i would not bother to change the plugs.  Spark blowout is not an issue, and the DOHC chamber does not need a really cold plug.  The FRPP TVS kit raises boost to 13psi and they don't require changing plugs.

Thanks guys for your advise, I had read that some were changing their plugs and other were not. So for me I'm going to see how she runs on the stock plugs. Check my tune with VMP in Feb when we meet in Ovedo for the horse power on the farm meet.

If some of you guys who want to install a 2.6 pulley on your stock eaton, PM and I can give you a link. Joe G has great tutorial with pictures. Unfortunately I cannot post here because teamshelby.com does not allow external links.

Thanks

We should have a tutorial here on Team Shelby by a Team Shelby member, which I think we do. I'll look for it.

Great write up!!  I am going to be changing the plugs on my son's car before we take it to the track.  We have the TVS, but I am going to be putting the stock plugs back in.  A few questions.  What are the stock plugs and I am assuming that you can simply get them through Ford?  What is the gap on the stock plugs?  What is the torque specs for installing the new plugs?  Appreciate the info!

The only one i've seen is Grabbers post with the new VMP puller tool and stock (look)pulley. Which is very helpful btw. What i was hoping to find was an successful install with the metco 2.6 pulley and aux idler with pics but i haven't yet (with the exception of the outside link).

Im sure someone will find something.

Thanks

FYI, NGK TR6 is the same heat range as the stock GT 500 plug.

Here is the link to NGK's online application guide:

as Justin stated dropping the heat range is not that critical for most GT 500s.

Directly from Evolution Performance site:

"NGK TR6 Spark Plugs Replace your stock plugs with these NGK TR-6 Plugs, their one step colder than stock. Must be used with Shelby GT500's running more than stock boost. "

I have the 2.6 Metco pulley and aux idler, I can take some pics for you if you'd like.
