RX7 mark 1. Wouldn't rev past 6000 with Champions, replaced with NGK and sang like an angel. It's not the price, it's the quality.

Pros: improved engine performance
Cons: poor engine performance

Go NGK and Iridium. They are a better spark and help burn any sediment off the tip. Also bonus is, they last about 50-80,000km.

Pros: better spark, burn sediment
Mileage: 50000 km

Just another rare earth metal to charge the user more for. Factory specs call for NGK Iridiums. I can't see a reason to deviate.

Cons: expensive, no reason to deviate
