Authencity ?? Worked out well - After being told that my poorly running Yamaha F250 was not worth fixing and I needed a new motor, by a reputable dealer>>>> I went trouble shooting "old school" and found a spark plug issue. So I figured for $50 bucks instead of $30k it was worth a gamble. The boat has never run better !!!! What haunts me is the question about authenticity of the plugs... The plugs and the boxes all looked real to me but maybe I am paranoid. If it walks like a duck and quacks like a duck, is it really a duck ??? LOL Review: Plugs verified by NGK to be authentic - 2007 Toyota FJ Cruiser. LFR6AIX-11 (stock number 6619). NGK makes truly great products and the result is many fake products are on the market. I sent pictures of the plugs to NGK for authentication and the reply was positive. NGK corporate is really good about taking the time to help you, they are very nice with very quick replies. Overstock Direct is an authorized reseller on desertcart, however, the Visit the NGK Store link associated with Overstock Direct has no association with NGK corporate. Having said that, I am happy with the purchase I made. I will post the pictures I sent to NGK. Look at the way the Iridium positive electrode post is shaped. It is cone shaped with a small protruding nipple on its center The numbers are on the plug’s hex base, vivid, deep and clear to read. The lines going around the porcelain top are sharp, vivid and not washed out. Now you know how to spot fake NGK Iridium plugs. I will purchase from Overstock Direct again. Hope this helps. ## Features - Iridium Spark Plugs - Designed to operate over a much wider heat range than ordinary plugs - Resists carbon buildup and pre-ignition - Patented triple gasket sealing process eliminates the possibility of combustion gas leakage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IAGN4UY | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #5,268 in Automotive ( See Top 100 in Automotive ) #15 in Automotive Replacement Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Car, Truck | | Core Material | Iridium | | Customer Reviews | 4.7 out of 5 stars 3,094 Reviews | | Included Components | 6619 | | Item Weight | 11.5 ounces | | Manufacturer | NGK | | Manufacturer Part Number | LFR6AIX-11 | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Model Number | 6619 | | Number of Items | 6 | | OEM Equivalent Part Number | LFR6AIX-11 | | Thread Size | 14mm (Thread Diameter), 1.25mm (Thread Pitch) | | Top Material Type | Iridium | | UPC | 087295066195 | | Unit Count | 6 Count | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** NGK - **Core Material:** Iridium - **Thread Size:** 14mm (Thread Diameter), 1.25mm (Thread Pitch) - **Top Material Type:** Iridium - **Vehicle Service Type:** Car, Truck ## Images ![NGK 6619 Iridium Spark Plugs LFR6AIX-11-6 Pack | Replaces 12565996 MZ602091 BY481-LFR6A SAB330NG4611 4704 5344 5618 IKH20 VKH20 IKH20TT 9613 9615 FR7N1133X 9775. - Image 1](https://m.media-amazon.com/images/I/61I-dQuimpL.jpg) ## Questions & Answers **Q: will those fit 2006 BMW E60 530i, built date 04/05 ?** A: Yes these will fit your e60 530i for sure. This plug will fit all n52 powered BMW's don't listen to these other guys who have no idea what they're talking about. There is no such thing as a "Toyota" plug or a "Honda" plug. Spark plugs are universal they either have the right threads and gap and electrical rating or they don't. BMW chose a style they wanted to use and OEM plugs for your car are actually rebranded NGK plugs. These will fit 100%. **Q: will it fit a bmw 2008 z4 3.0i** A: This is the same part number printed on the spark plug that I removed from my 2008 BMW Z4. I shot this video so I could make sure I ordered the exact same spark plug to replace what was already installed on my 2008 BMW Z4 3.0i. **Q: These spark plugs fits for a 2008 Lexus RX 350 ?** A: yes this is the correct plug **Q: Do they fit 2009 C230 mercedes??** A: Sorry Muhammad,I don't know but you can ask the seller.I recommend adding your vehicle to your Amazon garage ,in the auto section.Once this is done,you'll be able to find parts that fit your vehicle.It helps and if your not sure,it's best to ask the seller or research the internet.Good luck,hope this helps you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ??
