Is anybody running these? And if so, are they any good?

Thanks

My cousin has a 89 Z24 with a 3.1 turbo in it, and instead of getting his own screenname he uses mine. So I just was surprised when I loked and saw that I posted something with out knowing.

These ignition systems don't work well with platinum plugs.

AC Delco R42LTS plugs work the best. If you're running more boost than stock, you can gap them to .030".

I am not a big fan of autolite plugs, They only work good in Fords. Autolite has a very good race plug that I use on a regular basis but thats it... :icon_twisted:
TGPs work best with the stock plugs... ;)

I'm currently running autolite 103's in my black TGP. They've been in there about 2-3 years now and it runs perfectly.

Here's a quote from a rep at NGK that's sorta ontopic...

"You are correct that NGK is a supplier to General Motors. AC Delco is not a plug manufacturer but rather just GM's brand. NGK as well as Denso and I believe even Honeywell supply spark plugs to General Motors."

^Honeywell = autolite. ;)

On a similar note...What's the best spark plug wire?

I owe my friend a set... :icon_redface: Don't ask. lol

TGP Nick · May 02, 2009, 08:06:29 PM

Again, AC Delcos work great. I couldn't justify spending big $$$ on a spendy set of aftermarket wires when the factory ones work great.

For anything Ignition related, stick to AC Delco products.

Serge A. Storms · May 02, 2009, 08:16:06 PM

Well, the Delcos are $50 and Taylors are $64...ARGH! lol

TGP Nick · May 02, 2009, 08:39:57 PM

The Delcos can be had for a good price on rockauto ;)

I do like the Delco's when it comes to wires. ;)
