Early Boxsters sparkplugs should be changed every 30,K miles & that changed to 60K for the later models probably due to the improved fuel injectors & O2 sensors. Also worthy of notice is the high mileage acheived by this Boxster & in 2nd place Mac's at 256K, both original owners, both maintained properly at authorized Porsche dealers into the 200k mile range. This gives credibility to Porsche's criteria for "goodwill" out of warranty repairs.

Could you elaborate on this a bit. I'm new to Porsches but have a lot of experience with many types of machines, cars, motorcycles etc... I'm curious about the improvements to the FI and the failure mode of the plugs and O2 sensors in the early Boxsters. Also, how is the combustion event in a water cooled motor different then the combustion event in an air cooled motor?
