Cool. I'll be careful with them. I live in Michigan and it's really cold here right now. Do you think I run a greater risk of cracking/breaking a plug off when I'm trying to get it out in the cold weather? .
Hey, thank you so much for all this info! I had no idea I could find out right inside the hood what kind of plugs to get. Here's hoping the tune up goes well!
Okay, I'm not that mechanically inclined, but my '07 Liberty needs a tuneup in a bad way and I'm broke, so I need to do it myself. I know I need to get a spark plug wrench to change the plugs, but can anyone recommend a list of tools/supplies I should have on hand? Also... can you recommend...
