Hope you guys can help me as I am sure confused. I am also sure it has been posted.
What is the spark plug service interval for the RS4.
The manual says plugs to be changed every service, ie: 15000km,
but dealers tell me book is wrong and their program, which comes from Germany Audi, says every 90 000 km ???????
The plugs on my car were replaced at 40 000km so they say they will only replace them at 130 000km. I am on 90 000km at moment. ????
This was a free service they owed me, that is why I am being anal. I think they are trying to duck out of the plugs.
Any help appreciated.

You should change spark plugs every 60.000km. But in case of having your RS4 remapped I would do it a bit earlier (because of probably higher EGT and other factors). Of course in case of remap it's very reasonable to put in colder plugs (I use DENSO IRIDIUM IK 24).

Cheers.

Is 60 000km for DENSO IRIDIUM IK24, or will it be same for Original Audi plugs?

60.000 km - the same mileage for original and non original spark plugs, DENSO would be of recommended in case of remap.

Are you sure about this? My service book clearly states every 30.000 km for the RS4. And so does the "Self Study Programme" file that you can download here on the site...

when our RS4 gets a remap by MRC, is it easy to change spark plugs or is it a big job? would get the pre cats gutted while I was at it.
