Installed these NGK Iridium IX DCPR7EIX spark plugs in my 1999–2016 Harley Davidson Twin Cam, and the difference was noticeable right away. The bike fired up quicker, idled smoother, and throttle response felt more crisp. NGK quality speaks for itself. The iridium tip is known for durability and a strong, consistent spark, and that’s exactly what you get. They feel like a premium upgrade over standard plugs, especially if you ride often or want dependable performance. Fitment was perfect, no issues with installation, and they came properly packaged as a matched pair. For the price, it’s a solid upgrade that improves reliability and performance without breaking the bank. If you’re running a Twin Cam and want better ignition performance and long service life, these are an easy 5-star choice.
