Had a PPI done before I bought the car about a month ago and was told I should replace the coils as they are starting to crack.

FWIW you can also use a cheap endoscope to peek inside while you have the plugs out to see how the pistons and walls look.

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.

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

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

Had a PPI done before I bought the car about a month ago and was told I should replace the coils as they are starting to crack. Car has 43,000 miles now. I am going to do the coils next week. Should I change the plugs also? Any other suggestions? Thanks.

POST 2Original post

Yes, you are already there and the service interval is about every two years.

POST 3Original post

Spark plug intervals for the 987.1 are 36K or 4 years (or 40K and 4 years for the 987.2 ) No plugs require replacement at 2 years, and even four years is honestly on the short side if you're not doing a lot of miles. At 43K if you don't have any documentation of them being replaced, I'd just replace them. It's not much extra work once you've gotten the coils out anyway, and the proper Bosch plugs are not especially expensive if you buy from someplace besides Porsche . If they were documented done at 36K or 40K I would call them good.

POST 4Original post

Double ditto on not buying plugs from Porsche . The parts counter at my local dealer wants $36 EACH for plugs. I laughed and told the guy I was impressed he kept a straight face. Also, have your assortment of socket extensions and universals ready for the plug nearest the passenger/right side. Very tight spot but doable. FWIW you can also use a cheap endoscope to peek inside while you have the plugs out to see how the pistons and walls look. A few pics from my $30 scope at around 70,000 miles.

POST 5Original post

good info from all. what model scope did you get and where? very useful tool I do not have thanks

POST 6Original post

Adding a pointer for anyone coming across this thread: an assortment of locking extensions really helps with this job.

POST 8Original post

I did this job when I bought mine last year as well. Found that 3 of my coils were cracked. Make sure to get the new thicker coils. I bought the deep socket and used a swivel socket attachment and it was not a difficult job. I would definitely recommend doing the plugs at the same time as coils.

POST 10Original post

It was a $18 Fantronics scope from Amazon . I have used it many times to look at things on the car. Hard to argue with the price. https://www.amazon.com/dp/B07149K8QX/ref=cm_sw_r_cp_apa_EUBXBbC9GVWAE Sent from my VS995 using Tapatalk
