Is your Subaru with the 2.5L engine (like an Impreza, WRX, STI, Forester, or Legacy) running rough, misfiring, or throwing a check engine light for a cylinder misfire? A faulty ignition coil is a super common cause. Instead of guessing which one is bad, this 4-pack from Napol Performance lets you replace all of them at once for peace of mind and balanced performance. They're direct replacements for OEM part numbers like 22433AA418, 22433AA640, etc. New coils ensure a strong, consistent spark to all four cylinders, which can smooth out idle, restore power, and improve fuel efficiency. The installation is usually simple – just unplug the electrical connector, remove one bolt, and swap the coil. Doing all four is preventative maintenance, especially on higher-mileage turbo Subarus. Comes with a 1-year warranty. A straightforward fix that can make your Subie run like new again.
