Corvette Spark Plugs (Set) - Iridium IX : 1992-1996 C4
GM recommends checking and if necessary replacing your spark plugs every 35,000 miles.
Price is for a set of (8) plugs.
These NGK Iridium IX spark plugs feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plugs, and just thin enough to create an accurate and consistent spark. They represent the ultimate evolution of spark plug technology and performance. Iridium is significantly stronger than any metal used in spark plugs today. It's the hardest metal used (in fact, iridium is 6 times harder than platinum), which has allowed NGK engineers to reduce the voltage requirement for a spark.
0.6 mm iridium-tip center electrode provides durability and a high melting point
Taper-cut ground electrode shape provides improved flame reproduction
It is also recommended to check and replace spark plug wires at spark plug maintenance interval.
