Emissions

This part is not an emissions-related part and therefore can be used on Emission Controlled Vehicles.

Description

This is the factory spark plug as installed in the 2018 Subaru WRX STI Type RA and 2019 Subaru WRX STI. The main differences are a heat range that is one-step cooler as well as a slightly tighter gap than previous factory spark plugs. These serve as a factory replacement for the 2018 STI Type RA and 2019 STI and a great upgrade for modified 2.5L Turbocharged Subarus.

Why?

A good quality spark plug goes a long way in ensuring your car's engine is running smoothly. For years, tuners have been using an alternate solution on cars that needed a tighter gap and cooler heat range. Now available as an off-the-shelf plug, this takes the guess work out of replacing or upgrading your Subaru's spark plugs.
