(The maintenance code came on for new plugs and I bypassed it leaving the old ones in at the time about 5-10K KM's ago) and the car started to feel "sluggish" especially with it getting colder here in Canada. ## Features - Longer service life: the use of the precious metal extends the life of the spark plug compared to standard candles - higher change intervals, lower costs! - OPTIMIZED STARTING BEHAVIOR: The laser-welded high-fine iridium center electrode ensures perfect ignition performance and promotes the spread of the flame front in the combustion chamber. - Economical in consumption: the excellent ignition capacity contributes to a more efficient engine performance, reduces fuel consumption and environmental impact. - Notes: Please note the general installation instructions before installation - Box contents: 1x NGK spark plug laser iridium IZFR6K-11S ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0019VZYN2 | | Automotive Fit Type | Vehicle Specific Fit | | Brand Name | NGK | | Compatible with Vehicle Type | Car | | Core Material | Iridium | | Customer Reviews | 4.6 4.6 out of 5 stars (327) | | Gap Size | 5 Millimeters | | Global Trade Identification Number | 00087295152669, 00087295162408 | | Included Components | nothing | | Item Type Name | NGK 5266 Spark Plug | | Item Weight | 25 Grams | | Manufacturer | NGK SPARK PLUG | | Manufacturer Part Number | IZFR6K-11S | | Model Number | IZFR6K-11S | | OEM Equivalent Part Number | 5266 | | Thread Size | 14mm x 1.25mm | | Top Material Type | Iridium | | UPC | 087295052662 087295301883 087295152669 826732262000 652345452466 | | Unit Count | 1 Count | ## Product Details - **Brand:** NGK - **Core material:** Iridium - **Thread size:** 14mm x 1.25mm - **Top material type:** Iridium - **Vehicle service type:** Car ## Images ![NGK 5266 Spark Plug - Image 1](https://m.media-amazon.com/images/I/81O7PCgNFnL.jpg) ![NGK 5266 Spark Plug - Image 2](https://m.media-amazon.com/images/I/819LANJCXDL.jpg) ![NGK 5266 Spark Plug - Image 3](https://m.media-amazon.com/images/I/71J24N8RI4L.jpg) ## Questions & Answers **Q: Is this 4 spark plugs or one?? i am sorry to ask againg is not clear can someone please tell me** A: That is for one spark plug **Q: What socket size do I need?** A: you will need a 5/8th spark plug socket,3/8th drive ratchet and extension over 8". **Q: are these pre-gapped?? do they last much longer than non-laser iridium?** A: Spark plugs are pre-gapped but you should always check with a spark plug gap tool.

(The maintenance code came on for new plugs and I bypassed it leaving the old ones in at the time about 5-10K KM's ago) and the car started to feel "sluggish" especially with it getting colder here in Canada. ### ⭐⭐⭐⭐⭐ Review *by J***B on 13 July 2017* Got these for a 2006 Honda Civic with 125K on the original (NGK) plugs. I have had excellent experience with NGK plugs for many years in cars and power equiipment, so I always buy this brand if I can, even if it's a bit more expensive. Perfect fit, car ran a bit better (no surprise, given the miles on the old plugs). Have never had a bad experience with NGK plugs. ## Frequently Bought Together - NGK 5266 IZFR6K-11S Laser Iridium Spark Plug - Genuine Honda (25430-PLR-003) Transmission Filter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/279474602-ngk-5266-spark-plug](https://www.desertcart.co.uk/products/279474602-ngk-5266-spark-plug) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
