Default Spark Plugs???

Question?? Does it matter what spark plugs you use. Should I spend the extra money for the "quadro" or the "dual" spark plugs? Any help would be appreciated. I have an 84' if that helps.

P.S. What spark plug wires should I use?

If you're staying stock, I'd stick with AC Delco or Bosch.

As for plug wires,

Dave

My last wire set were the Taylor 8mm Spyro-Pro's, but I recently moved to the MSD 8.5mm Super Conductor's only because I needed to have a custom length. Otherwise, the Taylors were great and pretty reasonably priced.

Any copper core plug will do fine. Stay away from the gimmick plugs unless you like wasting money.

When I bought my car it had Bosch "gimmick plugs" which didn't look too bad with a nice light tan coloring- but the car just seemed to run rough cold. I replaced them with standard AC DELCO plugs -it ran and idled great!
The wires were not too bad and didn't look too old, but I have also replaced them and the the cap/ rotor -just so I know everything is current.
My car is all stock, so I didn't go with any real performance parts, except an Accel cap because it uses brass.

I do not know if it was a gimmick, but Horsepower TV did a dyno test with E3 Spark Plugs. They used the same engine with different spark plugs. The E3 gave the best boost in horsepower and gas mileage.

It was a test bed engine tuned to maximum output. Horsepower TV uses it to check the claims of the manufacturer of different products.

The test was a few months ago so I do not have all the details. I just wrote down the plug name to give it a try next time I need plugs. They do a lot of re-runs so I will keep an eye out for more detail. It is on cable on Sat & Sun.

you are not going to see a gain in hp from spark plugs.

DO NOT USE BOSCH!!!! you will be replacing them in a year!

No need for a gimmick plug
Plain old copper AC/Delco, if you want to spend more I like the NGK platinum.

i'm suprised to read that someone here uses NGK platinum plugs. they are excellent plugs and i use NGK plugs for my RX-7's and my Camry. my 84 has AC Delco plugs and they seem to work great! i may do more research on the NGK but i guess for now i'll stick with the oem replacement.
