Customer Reviews

I recently upgraded my vehicle's spark plugs to the Spark Plug and the results have been impressive. The enhanced combustion efficiency noticeably improved the overall performance of my engine, providing a smoother and more responsive driving experience, particularly during acceleration. The promised boost in fuel economy also held true, contributing to a positive impact on my gas mileage after just a few weeks of use. Installation was a breeze, even for someone with limited mechanical expertise, thanks to the straightforward process and clear instructions included. The durability of the SparkPlug has been commendable, showing no signs of wear or performance degradation under various driving conditions. While the higher price point and potential availability issues may be considerations, the overall benefits in engine performance and fuel efficiency make the Sparkplug a worthwhile investment for those seeking an upgrade in their driving experience.

This spark plug is the only plug my 2007 Charger 3.5 will accept. Tried other plugs, car misfired each time. Plugs that have to be "gap checked" do not fare well in the SXT model. These are less expnsive, but so what.. I change them every 25,000 miles anyway. It is a matter of preference, and I love preventative maintenance. Again.. you will do alright by these plugs.

Received it a little later than agreed. The pot was correct. It was a perfect fit. Overall we're satisfied.
