Alright well I order them anyway so we'll see how they do next week. Stock coil, stock everything 1.4

So, how did it go?

Just put them in this afternoon. So far so good, the old ones were definitely worn but not the worst I have seen. Car is otherwise stock. I wanted to do a ZZP coil pack at the same time but oh well, another time. Car has a P0420 code so I’ll be changing both front and rear cats at the same time along with new O2 sensors. Hope to keep the car for a long time still (already has 130k) so I figure I might as well knock that all out in one shot. Haven’t ordered those parts yet.

You have a leaking valve cover gasket...
That may end up causing a misfire from oil getting into the spark plug wells.
Get that fixed asap.
Why not try replacing the O2 sensors only first? It may solve the issue without the expense and labor of replacing the cats.
And if you do end up replacing the cats, don't go with aftermarket.
They will most likely fail and the P0420 code will return.
The GM cats are more expensive, but they will last.

I did replace the valve cover at the same time as the plugs. There was some oil present in the spark plug wells.
