Which Spark Plug?

[johnny classic]

I own a 1992 Corvette (LT-1) convertible Auto. trans and going to do a tune up starting with the spark plugs.
I was told that the E3.44 PLUS are the ones to use for this car.

Ideas or suggestions?

I would use the one GM uses, not sure whhat your LT1 takes. you will get a dozen different opinions, all of them as good as another.

I will only use OEM plugs.

I will only use OEM plugs.

I agree, when in doubt use what the manufacturer recommends.

If the engine is stock, then OE is a good place to start.
