NGK Iridium IX Spark Plugs

Designed specifically for the performance enthusiast. Iridium IX offers extreme ignitability, improved throttle response and superior anti fouling. Fine Iridium tip ensures high durability and a consistently stable spark. Iridium alloy has extremely high melting point, perfect for today’s high-tech, high-performance engines. “Trivalent Metal Plating” has superior anti-corrosion and anti-seizing properties. Outstanding acceleration, high fuel efficiency and durability. Ultimate design, technology and performance.

They sell for $6.99 a piece, plus tax, so you are looking at over $30 in spark plugs alone! They are gapped to Type-R specifications, I forget the exact gap. I used these puppies less than 100 miles, I like them, but I heard iridium is not the way to go for forced induction, which I honestly did not know. I am asking $20 plus shipping, which should be sub $5.
