Package includes: 2 NGK RE7C-L "leading" spark plugs and 2 NGK RE9B-T "trailing" spark plugs

Mazda uses NGK Laser Iridium spark plugs as their OEM choice, so this package will get you set up with factory replacement quality parts that will ensure proper performance and reliability you would expect from a brand new vehicle. This package is also what we used in our RX-8 Spark Plug Install Guide, if you are following the guide instructions you will need to pick up these plugs.

Laser Iridium spark plugs provide superior ignitability and long service life. Smallest tip diameter available Iridium / Platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions
