Spark Plugs
Thinking it is about time to change the plugs in the Cobra.
I believe they have around 20-25k on them, they are Bosch Platnium double electroeds which the former owner put in. I am thinking of just going to a standard replacement plug. The owners manual calls out for a AWSF-32C, which is different from the standard GT plug. Whats you opinions between a standard copper plug vs. platnium? From what I have heard, the copper in therory will give a little hotter and better burn, but will need to be replaced more often (which doesn't bother me). Opinions Please. Remeber it is a DD about 20k per year on the highway and I run 87 Octane.

Re: Spark Plugs
I would run the stock plug or equivalent (such as an autolite 764 I believe)
as far as I am concerned, the added cost for a platinum plug is un-necessary. There are no gains from running them

Re: Spark Plugs
i always liked NGKs for my weedeater
but i HATE those double tiped things, they made my tercel miss and knock and if they wont work in a 2.3L with something like 2:1 compression and 85 horse power i sure as hell would not use them in a nice car

Re: Spark Plugs
Copper has better conductivity, but the platinum is totally resillient to combustion heat and corrosion...and will still spark fine with 40k volts. Another platinum benefit: it assists combustion (a catalyst) so there are cleaner emissions...but so do catalytic convertors.
My next plug will be the ZEX (like the nitrous systems) plugs. They are a Nickel-plated copper "triple" electrode setup...durable and powerful; designed for turbo and nitrous...They're average about $5 though. As for multiple electrodes: I like the unshrouding of the spark...it can only mean more power and accurate timing.

Re: Spark Plugs
Is the Autolite 764 the right plug for my car as well?

Re: Spark Plugs
Platinums are for wear and corrosion. Copper is better for performance.
The iridium is a compromise between the two. Our Honda Odysseys and Pilots use NGK Iridiums. For a mustang, use copper...because they're cheap.
