My Insight has 72,073 miles, so I guess it's time. :wink:b1shmu63 said:In normal service the plugs are supposed to last 8 years or 72,000 miles and then get replaced.
Yeah, but you normally don't adjust the gap via the center electrode.b1shmu63 said:The electrode is Iridium and is needle like. I wouldn't mess with it.
Thanks for the info!b1shmu63 said:My info is that the gap when new should be 1.0 - 1.1 mm (0.039 - 0.043) inch, 1.3 mm service limit. Check with the dealer or the manual for your specific year/plug to verify this.
I guess something got lost in the metric-english conversion. <g>Shotster said:
