GO FIGURE !!

jp213a said:I went for the Denso IK20's due to the slightly smaller center electrode over the NGK (.4mm vs. .6mm) and the U-groove design. I paid $78 for eight with free UPS shipping. There's lots of info and hype on both company web sites.
Tinkerer said:The 0.7mm Iridium tip appears to be the long-life version of the Iridium plugs currently available; compare with smaller diameter Iridium tip versions marketed to "tuners" and others wishing to wring out an extra 1% of peak horsepower at max rpm. (WOW!) But those smaller diameter Iridium tips don't last very long; I believe Denso says to replace their 0.4mm Iridium plugs at 30k miles.
