"I needed replacement spark plugs, and this was the best investment for my car i have ever made, hands down. All of the good things people were saying about these spark plugs were true. The most noticeable improvements for my car were the quicker throttle response, a lower idle rev, and improved gas mileage. I rated them excellent because the product itself truly lived up to the hype. Thanks Auto Anything!!!" —Dorian B from Greensboro, NC bought a Pulstar Performance Series Spark Plugs for a 2006 Lexus IS 350, 3.4L V6.
