I was doing a bit of research into oxygen sensors and found this page on the web. Makes interesting reading.
Here's what they had to say about one of the sensors... "Double shelter extend maintains right building block degree of heat concerning faster reply epochs and protects the ceramic proper sphere for silicone polymer and top toxic condition"
Or how about..."This combined according to other Denso high-pitched character features including untainted nerve lodging and poriferous polytetrafluoroethylene filtrate entirely lead to do a longing lifetime oxygen sensor accompanying improved weapon public presentation and greater fire efficiency."
Anybody have a clue what this is all about ??
