Fyi: there are no spark plug wires on the 2.4.

 

thanks for the information. this makes the first car I have had that did not have plug wires

 

check out - https://www.chevyhhr.net/forums/maintenance-upkeep-50/checking-replacing-air-filter-10757/ which goes through the process of removing the Air filter housing which you will need to do to get at the plugs. One of the pictures partway down the first post in the thread shows the valve cover and the 4 coils which will have to be removed to get at the plugs. Not a difficult job at all. Good luck.

 

I use to up sale people to "better" spark plugs for their older Chevy's. Two weeks later they would return them for AC Delco's. My motto was Ford= Motorcraft, Chevy=AC, Mopar=Champion
