    Yes, that's the denso one. Which is good also.
    I'll have to find the one from illinois.... He shows the parts, like the oil filter.
    The cheap chinese copy one is soft and flexable. The Toyota one is a lot firmer, and solid.

    You are just kidding, right? Have you never had to fight out a small seized bolt????
    I know bosch coats the threads on there plugs... Not sure about anyone else.
