BB6'n till R34'n
Iridium and forced induction = BADI never said I didn't believe you, I ran coppers throughout the whole tuning process (NGK ZFR7F-11 to be specific) because they were cheap and I needed so many of them replaced. I got burned on my first set of $45 plugs (denso iridiums) when it was too early in the tuning process and Honda Bob put them in and subsequently fouled them in like 10 minutes.
But I had ordered another set well before the dyno day and when it came time to dyno tune we were nearing the end of our gains we could make until it was time to check the plugs and we ended up just slapping in the iridiums I had there and sure enough, it made 1 more horsepower than the coppers (which still looked in great condition I might add). So I figured after the tuning session I may as well keep them in, and I still have them in to this day. I am at the 4,000 mile mark I believe, since the tuning session and it still runs hard.
However, I'm always pulling for that last bit of horsepower and I believe in the concept behind these pulse plugs, but I just wanted them to explain if their plugs are conceptually the same as a regular spark plug when put into a FI environment concerning heat ranges and everything. If they could prove better, I would order a set just to test them out (and probably dyno test them all for you). But I won't destroy my engine (potentionally) if the heat ranges aren't compatible.
The tips are very fragile and can break off inside the cylinder.
