Guys I am up for a major service. My car is a XP50 running 1.3 (peak) boost with Cargraphic exhausts. I am at 80K miles; spark plugs were changed at 40K when car was tuned. Do I replace with stock plugs or are any other plugs needed due to tuning? I don’t know what the tuners have put in so I am stuck until car is in a garage. Also, it will be difficult to source whatever plugs might be in there quickly due to my location - Slovenia. What do you recommend? Should I also replace ignition coils whilst in there or leave them be if they seem ok and are taken out with care? Car otherwise runs without missing a beat engine wise. Thanks.

 

so your at 60k now? coils have been a recommended upgrade since you have them out doing spark plugs not a large expense some say dont fix it if it aint broke but other spend the 300$ for new coils while the labor is being done. also check your coolant tanks and clutch accumulator while its being serviced.

 

80K now. Different intervals in Europe. Accumulator changed. What's with the coolant tanks? Tanx.

 

coolant tend to get hot discolor and then crack n start leaking

id probably do a new serpentine belt if i was tearing stuff apart at 80k miles

at 80k if it was my car id do plugs/coils belt, inspect everything else check engine and transmission mounts wheel bearings front diff condition change oil.

 

You are overdue for a plug change. I would change them now. IMO, if the coils are fine - leave them alone.
