Ich wollte eigentlich einen Kerzenwechsel machen, aber das Wetter ist dafür eher ungeeignet.
Mein Fahrzeug hat jetzt 105.000 Km auf der Uhr und es sind die o.g. NGK Kerzen verbaut.
ALSO wurden bei meinem Maro schon mal ein Kerzenwechsel gemacht, weil Original ja sicher nur Delcos benutzt wurden !?
Jetzt frage ich mich aber, ob die Kerzen auch die Richtigen sind ???
EDIT (Scheint so):

Speaking of spark plugs, I removed one of my plugs for inspection this past weekend, as my car has some 59,000 miles on the clock. The wear appeared neglible but I noticed that the plug was non OEM. I purchased my '99 FRC in '01 with about 18,000 so, evidently, the previous owner changed the plugs.
Now the interesting part. The plugs are: NGK PTR5C-13. I have not seen this show up as a recommended plug? Is this perhaps an obsolete plug designation?
Thanks,

According to NGK you have a
P = Premium Platinum
T = tapered seat
R = Resistor type
5 = heat range about the same as the TR55
C = Special design firing end
13= plug gap of .052

He was the original owner of a '99 FRC and it had the NGK PTR5C-13 plugs in it, too.
I just changed the plugs/wires in my daughters' '99 coupe we bought in 2003 with 40K miles and they were...NGK PTR5C-13 spark plugs.
Obviously, GM used those plugs for OEM installation, I'm sure the previous owner didn't replace the plugs in your car or ours. Now for the best part, he had 110K miles on his plugs and we had 118K miles on ours and they still looked good...if I had known they were in such good shape, I would have left them alone until at least 150K miles maybe 200K. The original spark plug wires are the "spiral core" design with very low resistance and were also in excellent shape. As the miles pile up on this car, it's becoming more and more apparent that it's an easy 200K mile engine with only oil and filter (air and oil) changes. I change the oil strictly IAW the DIC and never before. Yours is still a baby at 59K miles.
