Review on NGK (6700) RE7C-L Laser Iridium Spark Plug: Unparalleled Performance and Durability in a Single Pack of 1 by John Hall

These are identical replacement parts for the OEM connector. For those who are swapping out their forks for the first time, remember that the RX-8 uses 2 different types of forks: Master and Slave. You will need two of these REC7C-L spark plugs and two NGK RE9B-T Laser Iridium spark plugs. Replacing spark plugs requires more effort than most other vehicles. You have to lift the car and do it from below. The plugs are hard to reach so make sure you have a good selection of extension cords in your spade kit.
