Can you even find replacements? I was thinking these were difficult come by and VERY pricey. But anyhow... if it was my car and I had reached the mileage required to change them, I'd change them and use stock NGK's. What is the part number on the ones you pulled?The maintenance indicator is telling me is due to change spark plugs, should I change them? I will attach a photo.
I don't think aftermarket spark plugs exist for the Insight. You can get the genuine Honda spark plugs under $30 each at most online Honda dealerships. Sounds like a fair price for 100,000 miles before you need to replace them again.anyone use a different plug that was less expensive but still worked well?
