Spark Plugs

Craig K. · 11-30-2005, 07:44 PM

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.

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

it's hard to beat the 764's, inexpensive and readily available

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

the copper will carry more current(amps)

i have seen the tips of the +2 and +4 bosch plugs break off in the motor .....

gimmick .....oh yeah

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.

im sticking to the autolites and or motorcraft
might try the platinums though

TheJeanyus · 12-02-2005, 03:29 PM

Is the Autolite 764 the right plug for my car as well?

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.
