Tune up recommendations

Hello all, I'm looking to do a tune up on my 01 ML320. I'm looking to replace the spark plugs, spark plug wires, air filter, and cabin air filter. Am I missing anything? What spark plugs should I get?

I'm also going to replace the battery and the thermostat and do a coolant flush. Which coolant should I use?

Any other recommendations?

M/B used NGK, Bosch & Beru for OE plugs. Use the NGK.

You will also need the boot removal tool. Also buy a small package of dielectric grease to lubricate the boots of the park plug wires.

Yup just use it as a lever and the valve cover as the fulcrum. Give the boots a slight twist first to break loose the seal formed on the plug ceramic and the boot.
