Review on Autolite XP3922 Iridium Spark Plug by Jason Jones

These spark plugs offer excellent ignition and help to keep the engine running smoothly and efficiently. The iridium construction ensures a strong and consistent spark, which translates to better fuel efficiency and engine power. The only downside is the slightly higher cost compared to traditional spark plugs, but the added performance makes it worth the investment. Overall a great choice for any automotive enthusiast looking to improve their vehicle's performance..
