Where are you and what model year Insight?My factory plugs didn't make it to 120k - #4 on MM at 100k both my hondas have been that way, E3s are guaranteed for 5 years/100k - and I bought all 8 for less than the price of 2 NGK. I bought the insight 2nd hand with 40k miles on it- it's never ran well from day 1 - lots of low speed bucking and shuddering; almost like an old manual shift when you shifted too soon, anyhow I'm hoping these help. It's definitely not my favorite car of all time but it's never left me stranded
had something similar happen to a customer who ran the 4 pronged bosch plugs, however i don't know if he ever bothered trying to get them to pay for repairs. wasn't a honda but still, i don't recommend anything more than 2 pronged plugs, mostly because there is no point to more than that. valves were bent and the engine had low compression on multiple cylinders and wouldn't drive anymore.I am not normally in the 2nd gen section, but when I saw E3 plugs, I had to respond. I put a set in a Chevy 350 engine. In less than 100 miles, the tip they weld to the electrodes came off and wrecked the cylinder. They DID stand behind their plugs...after they examined the plug, they paid for repairs (I just went ahead and installed a rebuilt engine).
Just a warning.....
happens all the time actually.Can't remember seeing plugs where the porcelain was burnt like that
Thanks! I just picked up the same plugs today along with the anti-sieze, socket, socket extension, etc. Hopefully it's as easy as it seems on the guide I've seen here. After the 30% coupon, all parts were 57 dollars vs 380 quoted from dealer.I've driven the car all week with no issues, doesn't seem to be any noticeable difference. They are guaranteed for 100K and the price is way less. It's not a hard job to do so why not try something different? Hopefully by the time 200K rolls around on the clock- I won't own the car anymore
