Spark Plugs...
 

Hi all,
I am new to this forum and have had zero exposure to forums in general, basically Im a noob.
However this noob needs some help please.
I have just bought my first Audi, it is a 2006 A4 petrol non turbo.
I have 2 questions initially the first is that I am puzzled as to if my car is a B6 or a B7 and how to tell the difference, and the second is are the spark plugs different between the 2 and if so how?
I was sold NGK Laser Platinum Part# PFR6Q, will this be correct for this car?
Please see my attachments for 20170925_173414.jpg and this 20170925_173705.jpg for my pictures.

Can anyone tell me why my car has a B6 stamped on the compliance plate instead of a B7?

If anyone can help[ me that would be great.

Thanks.
