Review: Worked beautifully on 2005 Toyota Avalon - Got these cause they were cheap NGK Iridium plugs. Please to say these were great quality, especially for the money. Now my 2005 Toyota Avalon Runs smoothly again. And after a few months is still running great with no misfires! Will buy again. 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 | #10,108 in Automotive ( See Top 100 in Automotive ) #44 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 3,049 Reviews | | Included Components | 6619 | | Item Weight | 0.01 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 | 1.0 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 ![6619 Iridium Spark Plugs LFR6AIX-11-6 Pack - Image 1](https://m.media-amazon.com/images/I/61I-dQuimpL.jpg) ![6619 Iridium Spark Plugs LFR6AIX-11-6 Pack - Image 2](https://m.media-amazon.com/images/I/513YvIZnKCL.jpg) ![6619 Iridium Spark Plugs LFR6AIX-11-6 Pack - Image 3](https://m.media-amazon.com/images/I/51iedc9KuaL.jpg) ![6619 Iridium Spark Plugs LFR6AIX-11-6 Pack - Image 4](https://m.media-amazon.com/images/I/510GetF1+GL.jpg) ![6619 Iridium Spark Plugs LFR6AIX-11-6 Pack - Image 5](https://m.media-amazon.com/images/I/61lG4cIhFVL.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.
