Hello. This is YA_Mech. I'm Yamekanik.
2015 Subaru BRZ
Maintenance Details: Ignition Coil, Spark Plug Replacement
Official Service Center Estimate: $1,000
DIY Cost: $150
The space was so tight that it was difficult to do, making it not recommended for DIY beginners. Subaru is not a common car in Korea, but it's a popular brand in North America.
Unlike a standard engine, the ignition coil and spark plug are mounted on the side, making them incredibly difficult to remove. So, while I was removing the engine, I also replaced the ignition coil.
