Just replaced the sparkplugs and found the 3 coils on the left hand bank have hairline cracks in them, nothing like some of the photos I have seen and not giving any issues but probably need to be replaced.

Can I replace only the left 3 (and I guess it has to be at least 3) with the modern part number?

The new and improved bigger coils ARE supposed to be more resistant to cracking that the earlier coils were prone too, but if you're only doing three of them it is best not to mix using the two types of coils.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi All I have a 2005 997.1 C2S down under. 65000km. Very good dry conditions, NZ new car so no salt/rust etc. Just replaced the sparkplugs and found the 3 coils on the left hand bank have hairline cracks in them, nothing like some of the photos I have seen and not giving any issues but probably need to be replaced. Now, these part numbers are: On my car: 996 602 102 00 (short bolt) Supposed to be from the parts Katalog (short bolt): 997 602 104 00 From Pelican parts (long bolt version): 997 602 104 02 So my first question is: Can I replace only the left 3 (and I guess it has to be at least 3) with the modern part number? (short or long bolt) And: are the short and long bolt versions any better/worse then each other? I.e stay with short bolt or not. And: why does my car appear to have 996 coil packs on it??? (which are even older than the 2005 997 parts katalog number), 996 602 104 00 Thanks

Your car in an early 997 and having the 996 part number coils does not surprise me. They do stuff like that, not to worry. The new and improved bigger coils ARE supposed to be more resistant to cracking that the earlier coils were prone too, but if you're only doing three of them it is best not to mix using the two types of coils.
