Hey guys. I've got a 2003 2.0 4Cyl 4WD Tracker and I'm trying to replace my spark plugs, but I'm not sure exactly where they're at. There's a set of 4 valves along the left side of the engine (standing in front of the car looking in) and 4 covers on top that don't quite look like traditional spark plug covers. My guess is that the ones on top are the spark plug covers, since the ones on the side have a bar bolted down to protect the covers, but I'm not sure. Does anyone happen to have a picture or know which is which? Thanks!

 

the 4 "covers" along the top are your coils. your have 1 for each cylinder. remove the bolt and electrical connector. and pull up with a twisting motion to remore coils and you should be able to access the plug with an extension and socket.
