Changing Spark Plugs in 02 C4S

[demosan]

I need some guidance from the guru's here as I am performing the 30K scheduled maint. on my 02 C4S. I have pulled the plugs to look at them and they don't look bad but after reading lots of posts about spark plug life on this forum I thought it would be time to replace as car is beyond 4 yr. recommendation, although milage is only 29K. The plugs in the car are Bosch platinum +4 plugs ( FGR 5KQED ) . I am not sure as to whether this was the OEM factory plug?? I bought the car at 23K miles a year ago and the owner had all records and he had not performed the 30K scheduled maint. so I am puzzled as to why they wouldn't be Beru's which I was lead to believe were the OEM plug??

Any recommendations as to what I sould replace with?? I do not track the car, but drive it regularly predominantly at "speed" :D on freeways !!

TIA demosan

Save your money and just pick up the NGK BKR6EK plugs for $30 for all 6..

Some cars came with Beru some with Bosch, NGK's work just fine.

Your 02 car has a 60K plug replacement interval (the +4 electrode plugs last 60K +). If you really feel that 30K replacement buys something, then save some money and get the older 30K plugs that were used in the 99 though 01 cars.

OE,

I realize the interval in the maint. schedule references 60K, but also suggests replacement after max 4 years. I assume this is meant to account for simple corrosion of plugs over time regardless of milage. Being I'm in SoCal and a dry climate I may just leave originals in there for a while as they look "normal" and I haven't had any CEL or related issues with sensors etc. ( knock on wood). Fuel consumption is what it was whe nI bought the car and no oil consumtion at all that I can detect. Changing them may be a true "over-kill" in anal retentive behaviour ;)

Thanks for the replies!!

Hi,

On the same note for my 2003 996 4s should I also purchase the NGK sparkplugs? I bought the car with 32,000klm on it and it now has a little over 41,000klm. I cant find the owner's previous records. I was told that he took it in and had it "serviced" right before I bought it and I was told to change the oil now. Is it necessary to change the plugs or should I wait. I do very little mileage in this car......10,000 klms in 16+ mos. The post says to change them in 60,000klms or 4 yrs.

Thanks

George

I just had my 02 996 cab serviced yesterday, and asked the tech to replace the plugs simply because they were 5 years old. I could be mistaken, but I'm sure the car is a little smoother now, both at idle and on the throttle. I didn't think there was anything wrong before, but...

I would suggest it's worth it - it's not exactly a lot of money if you are doing it yourself, after all.

I think it is probably too early to change spark plus. If you do though, make sure you tell them to CALL YOU if they are going to replace anything else. When I had mine replaced they replaced all six ignition coils because they were beginning to crack - without asking of course.
