Chrysler: double tipped electrodes = more power?

Hello,

I used to have 1971 Alfa Romeo 1750A Berlina (one of the 249 Berlinas
fitted with experimental automatic gearboxes). That car specified the
four-electrode spark plugs and recommended Golden Lodge. They were quite
expensive in early 1980s at $4 per unit.

One day, I decided to go cheap way and used the 99-cent single electrode
ones. The performance suffered, temperature soared (dunno why it was
that way with one but not with four), fuel consumption increased,
roughness magnified, etc.

My mechanic wasn't sure why they seemed to do better with Golden Lodges
than regular ones. The electrodes appeared to be very stunted and
shorter than the length of fire point.

So word of the wise: follow the manufacturer's specifications for the
spark plugs...regardless.

Regards,
Oliver

I'll second that recommendation. FWIW, I've also had good results with
Autolites in all of my family's cars and small engines (chain saw, weed
whacker, lawn mower), and the NGK plugs in my Nissan outboard (and the
Mercury before it) have been great. For whatever reason, the NGK plugs
seem to corrode less than any other brand in a salty environment.

Yup, unless you have those early GM cars with transverse-mounted V6 and
V8 motors. My Chevrolet was almost impossible to work with. That is,
until I found the "serpentine" extension rod and used a careful
manipulation to replace the firewall side of V6 motor. No, my Chevy
wasn't one where one can loosen the dog bone horizon mount and list the
motor forward.

I'd rather have the spark plugs that 100.000 miles than try to work my
way through the maze of components and like.

Along the same lines, there's a Mexican restaurant right near where I
work called "La Gringada..."

In any case, I'm not a big fan of fancy spark plugs, and that includes
pretty much any platinum (including Bosch, although the regular old
Supers seem to work fine) some engines do recommend the multi-electrode
plugs but for most normal engines there's really not much benefit.

Weird multi-electrode plugs don't do anything for you. You won't
notice any difference.

The only advantage platinum plugs have is that they wear much, much
slower. They make no difference to how the car runs. For a normal
ignition, platinum only helps on the center electrode, since that's
the one that erodes.

If you have a one-coil-per-two-cylinder ignition setup, the center
electrode erodes on half of them and the ground electrode on the other
half. Double platinum plugs help wear in this case. But again, you
won't see a performance difference.

I may be the only person in the world to have ever had good luck with
Bosch platinums (with the almost invisibly small center electrode) in
a Chrysler 2.2. I've actually never had bad luck with any plugs.

The car is a 1998. Wow, thanks for all the helpful comments.

But if what you're saying is correct, I SHOULD be using "twin ground
electrode platinum-tipped spark plugs" because my users manual says to only
use those "for your engine performance"!

There seems to be alot of negativity wrt this type of plug (and its
pricing).

Yeah, Wal Mart has Autolite Platinums for basically $3.88 per pair. I'm
thinking these would be the best bet and a better choice than just the
cheap non-platinums. Thanks again for the useful comments you guys.
