Show original supplier description
The NGK 4469 is an Iridium IX Series spark plug engineered for performance-driven vehicles. Its fine wire iridium center electrode is exceptionally durable and ensures a consistent spark, leading to improved acceleration and better fuel efficiency. This design also contributes to greater ignitability thanks to the tapered ground electrode. Constructed with an iridium center electrode, this spark plug is significantly harder than traditional platinum types, promising longevity and stable performance. 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. Customer 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. While some users note that these iridium plugs may not be identical to original equipment for certain Nissan models, they are often a more cost-effective alternative and are trusted for their quality and durability.
