Review on 🔌 Champion Copper Plus 446 Spark Plug: Long-lasting Performance in a Carton of 1 by Michael Barrett

Amazing! These are great candles! There were dropouts and jerky idle times. The coils are well tested so I decided to start with the cheapest part of the ignition system. Replaced all 16 spark plugs with these copper ones and what a difference! Now the idle is calm, the large camshaft rumbles pleasantly and does not slow down when starting and accelerating. Went with copper spark plugs because copper is a better conductor and will spark hotter than any other type of spark plug. Copper might not last long, but they're better for performance than those crappy platinum ones. These will be the only forks I will buy from now on! BUY IT!
