Escaping input for WMI Query

I'm creating a PHP package for querying WMI objects, and I'm wondering if there's a need to escape strings inserted into WMI queries?

If so, how do I parametrize and escape strings in the query since I can't use things like PDO as it required a PDO connection?

For an example query:

$value = 'PC';

$query = sprintf('SELECT * FROM Win32_LogicalDisk WHERE SystemName = "%s"', $value);

$connection->ExecQuery($query);
