I did use a little anti-seize, but everywhere I read that it's not necessary. The one thing I had to search for is the torque spec since I would rather rely on that than some fraction of a turn. The best I could find out was that I needed to be in the 20-30 N-m range. I set it at 25 and they seated nicely. The rear 3 were extremely difficult to access, but that's the car design, not the plug problem. I do feel like the car is refreshed and has a bit more power than the ones that had 110k miles on them. This should be the last set I will ever replace on this vehicle before getting rid of. Quality of the plugs seemed very solid and the price was perfect. I can't speak to mileage or longevity yet. Seems worth the money. Review: Excellent product. - They worked perfectly in my Suzuki Grand Vitara. Genuine product. ## Features - 6 pack DENSO Iridium Power 5304 Spark Plug - IRIDIUM POWER - DENSO 5304 - 1order = 6 Pieces ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00TQMTAU4 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #604,021 in Automotive ( See Top 100 in Automotive ) #3,141 in Automotive Replacement Spark Plugs | | Brand | Denso | | Brand Name | Denso | | Compatible with Vehicle Type | Car, Truck | | Core Material | Iridium | | Customer Reviews | 4.7 out of 5 stars 753 Reviews | | Included Components | 5304 | | Item Highlight | Replaces 5614257 EBC8143 09146367 12610767 12787099 1822A002 1822A069 19185432 19302724 25108074 272344-0 4671 057 5269 556. | | Item Weight | 0.27 g | | Manufacturer | Denso Sales California, Inc. | | Manufacturer Part Number | 5304 | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Model Number | IK20 | | Number of Items | 1 | | OEM Equivalent Part Number | 003 159 78 03, 09146367, 09482-00508, 0K23A-18-110, 101 000 004 AA, 101 000 041 AC, 101 000 054 AD, 12 12 9 071 003, 12610767, 1822A069, 22401 AA550, 22401 AA730, 22401-7B006 | | Thread Size | 14mm x 11.2mm | | Top Material Type | Ceramic | | Unit Count | 1 Count | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** Denso - **Core Material:** Iridium - **Thread Size:** 14mm x 11.2mm - **Top Material Type:** Ceramic - **Vehicle Service Type:** Car, Truck ## Images ![Denso # 5304 IRIDIUM Power Spark Plugs -- IK20 --- 6 PCSNEW -- - Image 1](https://m.media-amazon.com/images/I/81QaSO700wL.jpg) ![Denso # 5304 IRIDIUM Power Spark Plugs -- IK20 --- 6 PCSNEW -- - Image 2](https://m.media-amazon.com/images/I/71n7ijzxtYL.jpg) ![Denso # 5304 IRIDIUM Power Spark Plugs -- IK20 --- 6 PCSNEW -- - Image 3](https://m.media-amazon.com/images/I/61UEXP5e0XL.jpg) ![Denso # 5304 IRIDIUM Power Spark Plugs -- IK20 --- 6 PCSNEW -- - Image 4](https://m.media-amazon.com/images/I/71EyFkUtbML.jpg) ![Denso # 5304 IRIDIUM Power Spark Plugs -- IK20 --- 6 PCSNEW -- - Image 5](https://m.media-amazon.com/images/I/61KXBFwW3dL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for 2005 Camry XLE *by B***R on May 18, 2022* I bought these a few months ago, but just installed yesterday.
