Any suggestions for new coils?

The Jag STR has a 4.2 AJ engine. Not only is the LS a different size, but it's also unique to Ford. IIRC the closest Jag variant is a 4.0. They're all in the AJ family, but they're all a bit different. Trying to fit the Jag SC to the LS is like trying to fit Mustang 3v 4.6L parts to an Explorer/Vic 2v. Both are modular Ford engines, but they have different heads, intakes, etc, and aren't all that compatible.

The blocks are the same.

The blocks are the same.

I thought that some of the passages were different?

After further review (and investigation) I sit corrected. The block, crankshaft, pistons, and connecting rods are unique to the LS. I wonder how much extra that cost!!!

Upfront cost more, but I'm sure they've made the money back on being exclusive!
