Ignition coil set

[kristian813]

Hi, I'm getting ready for my 60 000 mile service (to do myself) and I'm shopping for ignition coils, since they seem to be the most expensive part of the service. I've read about the coils starting with the serial number 996 and the ones starting with 997. I read that the 997's were the newest ones on the market. Is there a difference? I found a good deal on Ebay for the 997's for about $300, has anybody found a better deal anywhere? Link to Ebay http://motors.shop.ebay.com/sportsca...=1&_from=&_ipg= Kristian

I did my 60K, service about a month ago myself, I found out that I had a couple of hairline cracks on 1 coil and major cracks on another, ended up changing 2 coils only, you don't have to change them unless they are cracked or giving you problems.

Thanks for the info. I just pulled out my coils and checked them out. I had cracks on two of them too. I had one of them missfiring before. But now when i put them back, I have three cylinders missfiring. A few of them were a bit hard to get to so maybe I twisted them and ruined one of them, since they are probably pretty old to start with. I'm just going to buy all of them, so that I don't have to deal with them for a while.
Thanks

FYI: I used Bosch plugs instead of Beru, the 2 cracked one I had were the left and right closest to the bumper, which were the hardest to get to.

I found some on Vertex Auto for my 996 1999 for about $49 - $54 dollars

Hi,
I ended up getting the set for $239 from the same seller, since the price dropped, so I got a good deal. I replaced the coils and the car runs great.

where did you manage to get them at that price? did you use the 996 or 997 numbered ones?

[kristian813]

Hi,
I bought them on Ebay, it's the same link as on the first post. They just lowered the price $20.
They are the 997... ones.

I did the same thing. I ordered from e-bay for 279. I spoke with a couple of P car mechanics I know and they both said to replace all the coils at 60K. Better safe than sorry

Dont Replace them unless they are Cracked or throwing Codes... get them here http://www.e-partssales.com/miva/mer...y_Code=996elec

I just had my 60k Service done last week, had the Tech Inspect the Coil Packs, the Advisor said they are Visually Rusted but they are 100% in Working order... I dint have them replaced

The problem with that is if they crack later - they eventually will - and moisture gets in the crack and if you live in a place where it freezes the moisture will expand and the crack will become worse. This could lead to a misfiring, CEL, and terrible performance. Better to replace them and drop one potential problem from the bin as the car ages. Unless you don't plan on keeping it.

true...ever since temps dropped into the 30's and 40's here in WI my car has been running like crap misfiring. Put new plugs in, its a little better but my guess is the coils will need to be changed. Going to buy a set of 6 of those next.

Hey Kristian, in addition to the coils, what else is involved with the 60k service? Do you have a list of parts and things you did?

Thanks

[kristian813]

I replaced all my ignition coils since they started acting up after I changed the spark plugs. I didn't want to fix them one by one, since I didn't want to keep working on them. Also you get a better deal by buying them all at once.
I also changed the differential oil on top of checking these things on the car. It wasn't due untill 90 000, but I did it anyway.
On top of all this, change your three pulleys or at least check them throughly. One of mine broke just after 60 000 and I was lucky that it broke while I was driving 10 miles per hour. But it still twisted the pulley and broke the serpentine belt. I read horror stories about people driving high speed and the pulley twisting so bad that it broke the part of the engine wall off. They had to replace the whole engine wall...
The reason why they can make so much damage is that the bearing just simply locks up...

I forgot that I changed the brake fluids on my car too. That's an easy job with a brake fluid pressure pump.
