Has  anyone had any experience with Denso Iridium plugs ? The IWF-16 appears 
to  be the right 14mm seat x12.7mm (1/2") reach. This would be with a  
Pertronix II /Flamethrower II  ignition.

I have used the Denso plugs before. The company was called Nippon Denso  (ND) 
- They actually list Corvair plugs in their catalog. The old numbers were  
W16FSU and W16FPU. The FSU was a standard tip, the FPU was a projected tip. They 
 also had a W20FSU for the Turbo - a slightly cooler heat range. Their 
current  (2005) catalog lists the W16FSR as the standard plug for the Corvair motor  
1964-up and the IWF16 as their "Iridium Power", premium plug. Their catalog  
lists it as a crossover from the AC 44FFS. I have used the W16FSU on several  
engines. - Seth Emerson
