What kind of speeds did this run entail?
Prob 50 to 60 mph, Highway I mean, with tolls and idiots on the left lane talking on their phones..Not Interstate 75
Hwy time was around 15 to 20 min each way at the most I would say. The rest is city, my wife did not reset the odometer so I really and kinda guessing..

Thanks for the info
I'm not sure, exactly, although they are a Volvo-only shop, and tend to only use parts that last. they know which stuff is the junk. At about $60 for the entire job, I didn't think too hard about it. :D

It's a 99? You dont have any of that - each plug has individual coil packs on each cylinder. Unless you are getting misfire codes then you don't need to worry about them. Your car also only uses a cartridge insert oil filter. Probably OEM Mahle/Mann filters are still the best.

Rotor, cap, wires - all that is gone from the 1999.
