Ive looked all over the forum here and didn't find anything on this.
Is it worth buying and installing Pulstar Pulse Plugs on the AUDI a4 2.8? They come 25 bucks a piece, quite expensive but I have heard that It gives over 15 hp boost on the TT, so is it worth for the A4 B5?

Im getting misfire codes on my A4 in cylinder 2, so plugs are needed. Ive been looking at buying these for a while. Are they worth their price?
