How to Replace Spark Plugs Ignition Coils Spark Plug Wires 2008-12 Jeep Liberty

Ignition coils help your vehicle's engine run efficiently, cleanly, and smoothly. Rough running, lower than expected mileage, or trouble codes are sure signs that it's time to replace yours. Since worn spark plugs can damage ignition coils, it's best to replace those at the same time. And, since this model also uses spark plug wires, those should be replaced as well. This video shows you how to install new quality TRQ ignition coils, TRQ Performance spark plug wires, and new spark plugs on your 2008-12 Jeep Liberty. • Check here for more videos on the 2008-12 Jeep Liberty: https://www.youtube.com/playlist?list=PLJVpHWuCEUX9CAHC1hzA-wBtLP-tJwrFO
