Review on Denso 3137 Spark Plug by Mike Giri

When I tried this automotive spark plug, my car's performance and acceleration improved drastically... The ignition system runs smoothly and the engine now sounds like new. The plug not only allows for faster ignition, but also enhances fuel efficiency. The only downside is the slightly higher price compared to other plugs in the market, but the quality is worth it in the long run. Overall a reliable and top-notch product for ANY driver's ignition needs..
