Yes the 2.5 has 2 spark plugs per cylinder, 4 on the left, 4 on the right. I have seen them listed in craigslist before as an 8 cylinder :whatever:

It is commonly thought that the right side (passenger side in the US) only fire during the exhaust stroke which is what I was told but have never found solid evidence to prove it, that's why I didn't put it in this thread.

If Anthony says both are firing at the same time just double I would tend to believe it since he has been deeper into the systems than most people I have chatted with and has probably tracked the spark patterns on some sort of graph generated from some sort of gizmo he programmed using a laptop he found under a seat at a junk yard.

Now this is scary, my Dodge 4.7 had even compression throughout all the cylinders, nothing bogus in the oil,but a test revealed exhaust gasses in the coolant. Would miss at idle. Had a blown head gasket between 2 and 4 (same bank on a 4.7) but ran great beyond idle. :eek:
