Multi-brand Universal Spark Plug IKH22 5345 Compatible with Toyota Prius/Audi/Mercedes-Benz/Mitsubishi/Subaru/Honda

When your vehicle experiences rough idle, sluggish acceleration, cold-start difficulty, or noticeably higher fuel consumption, spark plug electrodes are severely worn or carbonized and should be replaced promptly. These plugs ignite the air-fuel mixture for proper combustion and power delivery while reducing emissions. This is a multi-brand universal iridium spark plug with part number IKH22 5345, compatible with Toyota Prius (2000-2015), Audi A4/A6 (2000-2010), Mercedes C/E-Class (2000-2010), Mitsubishi Lancer, Subaru Forester (2000-2010), and Honda Civic (2000-2010). During installation, use a torque wrench to tighten to the recommended torque, avoiding over-tightening or under-tightening and ensuring the spark plug gap matches the engine.
