Answer 1

You can convert this query to pre_pget_posts:

$meta_query_args = array(
    'relation' => 'AND', // "OR"
    array(
        'key'     => '_my_custom_key',
        'value'   => 'Value I am looking for',
        'compare' => '='
    ),
    array(
        'key'     => '_your_min_model_key',
        'value'   => 1453,
        'compare' => '>'
    ),
    array(
        'key'     => '_your_max_model_key',
        'value'   => 1923,
        'compare' => '<'
    )
);
$meta_query = new WP_Meta_Query( $meta_query_args );

And compare param details:

compare (string) - Operator to test. Possible values are '=', '!=', '>', '>=', '<', '<=', 'LIKE', 'NOT LIKE', 'IN', 'NOT IN', 'BETWEEN', 'NOT BETWEEN', 'EXISTS' (only in WP >= 3.5), and 'NOT EXISTS' (also only in WP >= 3.5). Values 'REGEXP', 'NOT REGEXP' and 'RLIKE' were added in WordPress 3.7. Default value is '='.
