Excellent Spark Plug for Smooth Engine Startup

This automotive spark plug provides consistent performance, smooth engine startup and improves fuel efficiency.It is built with high-quality materials that are durable and long-lasting, making it perfect for long distance drives. The only downside is that it's a bit pricey compared to other options on the market. Overall, it's a great purchase if you're looking for a reliable ignition part replacement..

Rough idle - reduced fuel consumption

I have replaced the Bosch 4x spark plugs I used in my 1998 Ford Explorer (which worked great) and probably done about 100,000 in less than 6 months with them driven performance loss of Ford OEM spark plugs. Idling is rough, cold starts aren't as quick, acceleration feels sluggish, and gas mileage is definitely reduced. After less than 10,000 with these plugs, I think it's time to cut my losses and get rid of them, even if the replacement is a serious problem, you know where.

Pros
  • Increases engine life
Cons
  • Not all will fit
