Thanks for the link to the other thread. No kidding on how hard they are, took me forever to drill out the old one while the exhaust was still in the car!joatmon wrote: ↑Sat Mar 12, 2022 7:10 amin viewtopic.php?t=47790 Mark posted a link to the Dorman 42009 anti foulers from autozone that he used, and then nato posted a bunch of pictures about the task, so check out that thread
those antifoulers are a hard metal, a bit of a chore to drill out the one
Thanks for this, I don’t have a drill press, so it would be very difficult for me to drill out the anti fouler. My research is bringing up M18x1.5mm thread pitch as the standard for most vehicles, so I’ve decided on specifically one of these 2 defoulers:CraftsmanQuad19 wrote: ↑Sun Mar 13, 2022 8:40 pm They sell actual o2 defoulers that bolt right on specifically for this purpose. No drilling or “spark plug defoulers” necessary. My car hasn’t had a cat for over a year now and never had a p0420. Just google search an o2 defouler and it’ll pop up
