Review: 絶対に買わないでください。詐欺です。4本分の値段で1本しか売っていません。 Review: 95 Accord EX owner. The shop I use chose to put copper NGK's in an engine swap. They were WRONG! These are made for this F22b engine! I've tried other iridium plugs and they were ok (couldn't tell much difference in engine response). These feel like the gas is double octane. They burn hard and give the proper ignition to each cylinder. It only stands to reason that if your older car needs a boost, this is the efficient way to do it, and if your new car should be better, make sure you get these! (Also, my seller was amazing at pricing!) ## Features - Machine-wound thread prevents baked on and cross-threads during installation and removal - Five rib insulators prevent flashover - Copper - Glass seals bond center electrode and insulator to create a gas-tight seal ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075CTRLLM | | Amazon Bestseller | #325,324 in Automotive ( See Top 100 in Automotive ) #2,323 in Automotive Replacement Spark Plugs | | Brand | デンソー(DENSO) | | Customer Reviews | 3.1 3.1 out of 5 stars (8) | | Date First Available | January 9, 2018 | | Is Discontinued By Manufacturer | No | | Item Dimensions L x W x H | 8.5 x 2.4 x 2.4 cm | | Item Weight | 0.28 g | | Item model number | IK16TT (4PK) | | Manufacturer | Denso | | Model | Spark Plugs | | OEM Part Number | ABARTH%4606591AA, ABARTH%4796779, ABARTH%56006240, ABARTH%SP00ZFR5AP | | Product Dimensions | 8.51 x 2.44 x 2.44 cm; 0.28 g | ## Product Details - **Brand:** デンソー(DENSO) - **Core Material:** Iridium - **Thread Size:** RM - **Top Material Type:** Iridium - **Vehicle Service Type:** UTV ## Images ![IK16TT Iridium TT Spark Plug - Image 1](https://m.media-amazon.com/images/I/71RjREPZYrL.jpg) ## Customer Reviews ### ⭐ Review *by D***Y on January 18, 2026* 絶対に買わないでください。詐欺です。4本分の値段で1本しか売っていません。 ### ⭐⭐⭐⭐⭐ Review *by J***I on June 17, 2024* 95 Accord EX owner.
