Some "data" in ES:
- Air filter MAPCO 65217; AUDI A4 (8E2, B6) 1.8 T 2002 2001 2000; AUDI A4 Avant (8E5, B6) 1.8 T 2002 2001;
- Air filter: Air filter MAGNETI MARELLI 153071760244; AUDI A4 (8K2, B8) 1.8 TFSI 2012 2011 2010 2009 2008 2007; AUDI A4 Avant (8K5, B8) 1.8 TFSI 2012 2011 2010 2009 2008 2007;
- Air filter FEBI BILSTEIN 48477; AUDI Q7 (4LB) 3.0 TDI quattro 2008 2007 2006; VW TOUAREG (7LA, 7L6, 7L7) 2.5 R5 TDI 2010 2009 2008 2007 2006 2005 2004 2003;
- Air filter: Air filter FRAM CA10236; AUDI Q7 (4LB) 3.0 TDI quattro 2010 2009 2008 2007 2006; AUDI A3 (8V1, 8VK) S3 quattro 2018 2017 2016 2015 2014 2013 2012; PORSCHE CAYENNE (9PA) 3.0 TDI 2010 2009;
- Inside air filter FRAM CFA8869; AUDI TT Roadster (8N9) 1.8 T 2006 2005 2004 2003 2002 2001 2000 1999; AUDI A3 (8L1) 1.6 2003 2002 2001 2000 1999 1998 1997 1996; AUDI TT (8N3) 1.8 T 2006 2005 2004 2003 2002 2001 2000 1999 1998;
etc...
So, i have response with score for data that contains Audi A3 lower than forexample Audi A4 or Audi Q7, etc.
Why is it so?
