Great Spark Plugs
The Denso Iridium Twin Tip spark plugs have two tips that allows for better spark distribution and more efficient fuel ignition, according to the literature. After installing them, I do believe it. The vehicle seems to be running a bit quieter or smoother, and it definitely seems to have a bit more pep. Have not used it long enough yet to determine if actual fuel efficiency has improved, but I would not be surprised if it has. Literature says these plugs are rated for over 100,000 miles, which is GREAT!
