Since I'm switching exhausts soon, I'm thinking of replacing my spark plugs and coil packs since they're now 10 yrs old with 33K miles on them. I've also been getting misfire CEL's and the removal of the exhaust and headers will make them easier to access.

In looking for replacements, I've found that Porsche made an "Updated" version which appears to have a larger head and requires longer set screws (Part no. 99760210402). Does anyone know what exactly was updated and if there are any benefits to going with these $70+ each coils, as opposed to the original design Bosch or Beru for half the price?

I haven't heard of any issues or recalls pertaining to coils that would explain the "update". Maybe they're less prone to cracking or something?

 

Updated....longer screws.... It is going to be interesting to install these without removing the engine.....It is so tight down there....

By the way the original Beru or Bosch are not half the price. They are identical.

Prices for these are less.
