I was just reading the "in ca. only" part of the coupon.
There is a California model of this engine that has passed some form of EPA type testing I assume.
Doesn't mean a thing if you don't live in CA.
I'm surprised at how many people have had so much problem with this concept of printing out a coupon & using it. :doah: Come on guys, don't make it any harder than it really is. :thumbsup:
