Product review (5 stars): ***Make sure you get the big pipe OVER the gas spout when re-assembling!
Exactly what I needed, but I didn't install it correctly at first.  The first time I tried to install it, the igniter would flash (it wouldn't before) and I could smell gas, but the oven STILL wouldn't light.  It's because I hadn't put the base of the big silver pipe (with all the little holes in it) back OVER the gas valve (which was kind of hidden underneath).  It was basically like trying to blow up a balloon by putting the balloon hole NEAR the nozzle of a helium tank, instead of putting it OVER the nozzle.
