I have an '07 MCS with ~45k miles. I was wanting to proactively replace the plugs and plug wires. Any recomendations?

 

Plug wires are going to be found in the same spot as the power steering fluid.

(There are none, as it is coil-on-plug). OEM plugs are good way to go. You need a special 12-point thin wall socket. I just replaced mine.

 

You can't replace the "wires" on this car. There are four separate coils for each cylinder. The main wire harness attaches to each coil with a levered connector on top of the valve cover. The stock plugs are good for supposedly 100K miles. I would just take a look at them and see if you really need them or not. A new set is going to run you around $60.

BTW, the R56 has an electrically assisted power steering rack. There is no power steering fluid.

 

I think that's what strobeyprobey was saying

 

Thanks everyone! Just been schooled!

 

With that mileage it's not a bad idea to replace the spark plugs, but at least you don't need any wires.
