Great product. - well packaged. used on Toyota Rav4 2002 2.0 Petrol Service :) Review: Five Stars - Car works fantastic now so greatful ## Features - Optimal ignition performance: The laser-welded iridium centre electrode has a diameter of only 0.6 mm. This keeps the ignition voltage requirement low and ensures a powerful ignition spark. - Long life: Thanks to the precious metal, the Iridium IX spark plug lasts up to twice as long as a standard nickel spark plug and, due to this durability, saves money and installation and removal time. - Full performance over the entire service life: With standard spark plugs, the distance between the electrodes increases over time due to burn-off. The quality of the ignition is impaired and misfiring occurs. With Iridium spark plugs, the electrode gap remains almost constant over the entire service life. - Notes: please read the general installation instructions before installing! - Delivery includes: 1x NGK spark plug BKR6EIX Iridium IX ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0019I33FQ | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | 73,158 in Automotive ( See Top 100 in Automotive ) 423 in Car Spark Plugs | | Brand Name | NGK | | Compatible with Vehicle Type | Car | | Core Material | Iridium | | Country Of Origin | Japan | | Customer Reviews | 4.6 4.6 out of 5 stars (340) | | Gap Size | 4 Millimeters | | Global Trade Identification Number | 00087295145890 | | Included Components | NGK Spark plug 4589 iridium tensioner size: 16 mm, thread length: 19.0 mm | | Item Type Name | Spark plug | | Item Weight | 0.05 Grams | | Manufacturer | NGK Spark Plug | | Manufacturer Part Number | IFR6T11 | | Manufacturer Warranty Description | 1 Year Manufactuer Warranty | | Model Number | NGKIFR6T11 | | OEM Equivalent Part Number | Toyota 90919-01210 | | Thread Size | M14 | | Top Material Type | Metal | | UPC | 087295145890 | ## Product Details - **Brand:** NGK - **Core material:** Iridium - **Thread size:** M14 - **Top material type:** Metal - **Vehicle service type:** Car ## Images ![NGK Spark Plug IFR6T11 4589 - Image 1](https://m.media-amazon.com/images/I/81xcg-U-zuL.jpg) ## Questions & Answers **Q: I have a 2002 Toyota camry 4cylender what is best spark plugs should I use** A: This spark plug I thought would be great for my 2004 toyota RAV4 and I have no reason to think otherwise after 1,000's of miles and about 2 years of use. **Q: My car calls for ifr6a11, but these are ifr6t11. does that one letter matter? it says here that they fit my car.** A: As best I can tell from the NGK site, the IFR6T11 is the new number for the same plug. NGK says it does fit my 2006 Camry 4 cylinder. However, there is a SIFR6A11 in the NGK site at a much higher cost. A warning comes up that it does NOT fit my vehicle. **Q: Is this just a single spark plug ? or a set of 4 spark plugs?** A: Come in single one , I bought 8 for my sequoie **Q: Do i need to use anti-seize on these spark plugs?** A: From what I read, you should always use anti-seize. I did and the little bit of money that it cost gives me a better piece of mind. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 2002 Toyota Rav4 2.0 Petrol - Service.
