View filter - Show content that has 1 field matching another field in current node

I have a content type called Specifications which has 4 fields

• Engine Specifications
• Features Specifications
• Variation (exposable filter)
• Model

I also have another content type called Cars which has 1 field called Model too.

I am created a SpecificationsView which displays the content-type Specifications as a block in Cars.

Is it possible to show in each Car the Specifications whose model matches the current ''Car'' node's model?

$nid = arg(1);$node = node_load($nid);$term  = $node->field_model['und']['0']['entity']->tid; return$term;
