Denso Irridiums are good, but they cost $12 a piece. They also come with a huge gap from the factory. Supposedly the tiny electrode can fire with a larger gap, thereby giving a larger spark. However, if you're running with high cylinder pressure, you might want to close the gap a little to prevent misfires (running 15 psi in my Passat turbo I had to close the gap a bit).
Originally posted by XSrcing alot of people go with the NGK copper tips. no real loss but they just dont last as long. plus they are only a fraction of the cost of the platinum.
