Reccomended plug leads?
 

Need to replace Spark plug leads on my S5 T2 vert,
What do you guys recommend?

Do you mean the leading spark plugs?

I would say most people use the stock NGK plug replacements unless their car is for race application.
You will need (2)BUR9EQ and (2)BUR7EQ. Not sure if it is different in NZ.

high-tension leads = spark plug wires

I use Magnecor 8.5mm wires. I like them because they haven't given me a reason not to.;)
