Product review (5 stars): I was a bit skeptical, but it worked!
The numbers on the igniter didn't match the original part, but it was a perfect match.  I have a Whirlpool Super Capacity 465 range.  It took me about 45 minutes with the help of my wife.  It's a bit awkward working inside the oven, and I needed to splice the wires into the old wires.  Make sure you cut the wires close to the old part.  The bottom line is it worked perfectly the first time.  We were looking into new ranges that would have cost us at least $800 installed.  We are now going out for a nice dinner.
