P0301 on my 2011 ML350 4matic W164
Just had this DTC recently and I plan to change the spark plug hoping it would fix the issue. But I have a question to ask if I have to change all the plugs or just the one on cylinder 1? What is the best type of spark plugs to use on this SUV? Thanks for the help.

100,000k/60,000m interval for plugs. Change them all if needed, I'd buy them from the dealer or OE plugs from a reseller.
If they are not due for a change, switch the coil with an adjacent one and see if the code returns and that should help determine if it's a coil or plug.
