I don't know about the "comparable", I just know they work just fine, some people want to spend the extra money for OEM replacement etc. I just know they work fine, and I know dozens of loopframes that are running them and they work fine. One good thing about it, if I EVER need one, I can pick one up any city any parts store any time, cheap!
Or any Walmart, for that matter!! Eric Lamberts ew-@unr.edu Reno, Nevada USA
