Cheap copper core plugs designed in the 1910's or the newest, most up to date plug you can get your hands on? I researched the problem. I looked at several brands and several styles from platinum, multi-tip, split-tip and so forth. I've used and thought kindly of the 4-prong plugs. Why did I switch? No particular reason other than I wanted the Iridium core. The spark plugs I removed were NGK. Not surprising as it was a Japanese vehicle. Ergo, back went the best NGK spark plugs I could find. These were well built, installed easily, and made a gratifying difference. Use anti-seize on the threads and spark plug grease on the tip. I expect another 50,000 miles from these plugs. Oh, I also change the spark plug wires when I change plugs. In my experience you can damage a wire just pulling it, or find one abraded from rubbing on a motor part. You are there anyway. Review: Polaris RZR 800 4 - My RZR didn't have any real issues, or so I thought. When I installed these as preventative measure since I had the rear end apart, I noticed the idle was a little smoother and I can get to my top speed a little quicker. My old plug boots had mud in them, that was more than likely the culprit, but I'll give these plugs the credit! ## Features - Item Package Dimension: 3.74L x 1.102W x 0.74H inches - Item Package Weight - 0.103 Pounds - Item Package Quantity - 1 - Product Type - SPARK PLUG ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0018JVDRG | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #761,686 in Automotive ( See Top 100 in Automotive ) #552 in Automotive Performance Ignition & Electrical Systems #3,972 in Automotive Replacement Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Bus, Van | | Core Material | Iridium | | Customer Reviews | 4.6 out of 5 stars 319 Reviews | | Gap Size | 0.6 millimeters | | Global Trade Identification Number | 00087295169889 | | Included Components | NGK 6988 | | Item Highlight | Replaces AGPR12P AGPS12P1 MZ602081 BY481-BKR7E JE45-18-110 999-06910-X9-030 3164 3334 IK22 K22PR-TP11 K22PR-ZU11. | | Item Type Name | Spark Plugs | | Item Weight | 3.52 ounces | | Manufacturer | NGK | | Manufacturer Part Number | 6988 | | Manufacturer Warranty Description | Manufacturer | | Model Number | 6988 | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | 1Y0B-18-110-MAZDA,22401-50Y07-INFINITI,22401-50Y07-NISSAN,22401-85E17-INFINITI,22401-85E17-NISSAN,22401-V5017-INFINITI,22401-V5017-NISSAN,5-8612-3953-0-ISUZU,8-9432-8375-0-ISUZU,8-94328373-0-ISUZU,90048-51079-000-DAIHATSU,90098-72047-LEXUS,90098-72047-TOYOTA,90098-72078-TOYOTA,91 71 307-SAAB,94702-00399-YAMAHA,94709-00399-YAMAHA,98079-5714E-HONDA,98079-5714F-HONDA,98079-5714J-HONDA,98079-5715E-HON… | | Thread Size | M14 x 1,25 | | Top Material Type | Metal | | UPC | 087295169889 | | Unit Count | 1 Count | | Vehicle Service Type | Bus, Van | ## Product Details - **Brand:** NGK - **Core Material:** Iridium - **Thread Size:** M14 x 1,25 - **Top Material Type:** Metal - **Vehicle Service Type:** Bus, Van ## Images ![NGK (6988) BKR7EIX-11 Iridium IX Spark Plug, Pack of 1, One Size - Image 1](https://m.media-amazon.com/images/I/813m1w7aM-L.jpg) ![NGK (6988) BKR7EIX-11 Iridium IX Spark Plug, Pack of 1, One Size - Image 2](https://m.media-amazon.com/images/I/81LkSFksCJL.jpg) ![NGK (6988) BKR7EIX-11 Iridium IX Spark Plug, Pack of 1, One Size - Image 3](https://m.media-amazon.com/images/I/61s7ZrNXTDL.jpg) ![NGK (6988) BKR7EIX-11 Iridium IX Spark Plug, Pack of 1, One Size - Image 4](https://m.media-amazon.com/images/I/61-dEsVKWsL.jpg) ## Questions & Answers **Q: Is this for one spark plug or a set of four?** A: Only one you will need to purchase 4 **Q: are these pre gapped ?** A: Yes Iridiums as pre gapped ## Customer Reviews ### ⭐⭐⭐⭐⭐ A high quality spark plug *by D***Y on September 8, 2015* So, when you or your mechanic feel you need new spark plugs what are you going to buy?

These iridium plugs are even better. I installed on a Polaris RZR 800. I see quicker starts, better idle, and maybe even an increase in horse power. I do recommend careful action to set plug gap. The iridium positive core is very small and might be damaged by efforts to set gap. I used a spark plug gap tool that allows careful bending of negative pole. ## Frequently Bought Together - NGK (6988 BKR7EIX-11 Iridium IX Spark Plug, Pack of 1, One Size - LOCOPOW RZR 800 Air Filter 1240482 1240434 for Polaris RZR S 4 800 EFI 2008-2014 Ranger Crew XP 800 2011-2014 Ranger 800 6x6 2011-2017 Performance - Genuine Polaris Part Number 2540086 - FILTER-OIL, 10 MICRON, for Polaris ATV/Motorcycle/Snowmobile/or Watercraft --- ## 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/4921512-ngk-6988-bkr7eix-11-iridium-ix-spark-plug-pack-1](https://www.desertcart.co.uk/products/4921512-ngk-6988-bkr7eix-11-iridium-ix-spark-plug-pack-1) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-10-18*
