This design maximizes ignition efficiency, accelerates flame growth, and ensures exceptional durability, delivering smoother engine performance and longer lifespan compared to standard spark plugs. Ideal for car and truck owners seeking a reliable, high-performance ignition upgrade. ## Description Increased performance with World's smallest Iridium Center Electrode (0.4mm). To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to increase, which has the opposite effect. Iridium Power uses DENSO's patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage. Review: High quality spark plugs with reliable performance - These Denso Iridium Power spark plugs are excellent quality and a great upgrade or replacement for many vehicles. The iridium design helps provide a strong and consistent spark, which can improve engine efficiency and smooth performance. Installation was straightforward and the fit was perfect. They are well known for durability and long lifespan compared to standard spark plugs. After installing them the engine runs smoothly and responds well during acceleration. Pros: • High quality iridium construction • Reliable and consistent spark performance • Long lifespan compared to standard plugs • Improves smooth engine operation Cons: • More expensive than basic spark plugs • May not provide noticeable gains if replacing newer plugs Review: Replaced along with some bad ignition coils - My 2017 Kia Forte was throwing out ignition error codes, so I replaced all the ignition coils and spark plugs. They arrived quickly, seem to be of good quality, and installed as expected. This happened about two years ago, and I have not had any issues since, so I would say that they are performing well. ## Features - 0.4 mm iridium center electrode: world's smallest diameter that maximizes firing potential - U-groove and taper cut ground electrode: provides faster spark flame growth and lessens heat quenching - DENSO patented 360 degree laser welding process: ensuring exceptional quality bond and structural strength with the iridium center electrode ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008NZCG2O | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #562,982 in Automotive ( See Top 100 in Automotive ) #3,176 in Automotive Replacement Spark Plugs | | Brand | Denso | | Brand Name | Denso | | Compatible with Vehicle Type | Car, Truck | | Core Material | Iridium | | Customer Reviews | 4.6 out of 5 stars 312 Reviews | | Gap Size | 0.9 Millimeters | | Global Trade Identification Number | 00042511053564 | | Included Components | 5356 | | Item Weight | 0.01 Ounces | | Manufacturer | Denso | | Manufacturer Part Number | IXUH22I | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Model Number | IXUH22I | | OEM Equivalent Part Number | 9004851189, 9676288180, NDIXUH22IA | | Thread Size | 1.25mm | | Top Material Type | Nickel | | UPC | 042511053564 | | Unit Count | 1.0 Count | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** Denso - **Core Material:** Iridium - **Thread Size:** 1.25mm - **Top Material Type:** Nickel - **Vehicle Service Type:** Car, Truck ## Images ![(5356) IXUH22I Iridium Power Spark Plug, (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/71j0LjNNt3L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality spark plugs with reliable performance *by S***S on March 6, 2026* These Denso Iridium Power spark plugs are excellent quality and a great upgrade or replacement for many vehicles.
