The link you provided for the Honda Accord Standard T EGR Valve. Is there really any difference inside the EGR Valves between the accord and the insight? I would assume since the accord is not a hybrid with the heavy NOx purges and leanburn ability it wouldn't be idle to mess with that
? Same reason a normal aftermarket catalytic converter wouldn't work.
Random note for anyone not interested in paying OEM price for catalytic converters, I have found Eastern Catalytic Eco III works well since it is designed with twice the amount of Rhodium to help on vehicles with high mileage, low emissions, or higher than normal emissions (like G1 insights). Best price I have seen for them is through Rockauto. I tried a Bosal New York/Catalytic Converter from autozone and it was not a direct fit and lost 18 Mpg vs bad OEM lol it was returned
.
I was considering the Airtex/Wells for $156.79 (on Rockauto's website), however it is only like $50 more for OEM. I would rather save the money though with the one you linked if there really isn't any differences that us insight drivers should be concerned about.
