Installed my Fab9 COP kit
That's funny, since I've run Toyota coils at that boost level with no issues and GM LS2T coils are way more powerful. We ran a set of LS coils at .070" plug gaps until the plugs gave up ~500 miles later.
I hope this clears the air about them being PNP for the 01+ cars.
The new MSM version on the left, and the previous (all other applications) on the right.

The standard coils we were shipping fit perfectly in the 01+ VVT cars but the feedback was that due to the powder coating on the MSM cars the fitment was a bit too firm.
Since then we've made a revision and offered to upgrade anyone who had already purchased the previous "firm fitting" version.

I know most have good results with them just sharing my feedback.
Well I think your problem is you were using the wrong coils. GM cops are ok, but the LS coils (cnps) are significantly better.
I've actually got a set of these but opted to do my own harness so they are not installed yet, so I do have a horse in this race. Bryan and I traded about 40 emails about these and hunting down the connectors so I've been impressed thus far. If I can dig up some TXL I'll be installing these over the weekend.

Nope, they have a slip fit, exactly like they would on a bike. Or even how your factory plug wires may fit. You can feel them "click" into place when they're seated all the way.
