The material specifications include an iridium center electrode tip, a ceramic insulator, and a standard configuration with a 1.1mm pre-gap size. Key dimensions include a 14mm x 1.25mm thread size, a 16mm hex size, a 14.0 mm thread diameter, and a 26.5 mm thread reach.\n\nCustomer reviews indicate that these spark plugs deliver noticeable engine improvements, such as a smoother idle, enhanced throttle response, and improved gas mileage. Many users report immediate performance gains and a smoother-running vehicle after installation. The pre-gapped design simplifies the installation process.
