Hi Audi Fans,


A friend of mine sent me the link below this morning:
http://www.off-road.com/products/reviews/directhits/hits.html

It sounds like a pretty cheap upgrade (if it actually fits) for my 5kcst's
aging ignition system.  I wonder if any lister has experienced or heard of
this ignition spark amplifier before??

Btw, what is the difference between non-resistor and resistor spark plug? Is
the Bosch +4 spark plug of the non-resistor kind??


TIA
