thanks

Just go with the stock plugs. Bosche. I changed my own within an hour using the correct tools.

Here's a good read for you.

Stock:-
BOSCH ZMR5TPP330

Tuned:-
NGK? Colder plugs with smaller gaps - someone tuned please chime in.

I use NGK 95770 (I think) with my stage 1 tune. I had misfires on the stock plugs and they weren't that old.

Otherwise the stock plugs mentioned above are the ones you need.

What's stock gap size just so I can check them please, especially when removing old ones

I remember when I had 36k good times.

Aren't they supposed to be changed around 30k or less? Have they already been done at some time? Are you doing them yourself?

Nope still original ones, no need to change as car runs like train and starts fine.I changed our CLK kompressor plugs a month ago at 48k,easy job straight from the top. I can do the M ones myself no problem, just do one side at a time moving things out the way...I always carry a new bosch spare coil in the car so it's always at hand.
You at work?

The connectors on the ECUs can be a pain so just be sure to get them connected up properly to avoid any issues.

No, we are closed currently due to at risk employees etc.
