Product review (5 stars): Fits MAYTAG -  a perfect replacement
Perfect replacement for my Maytag range (Model #MGR4452BDW - look behind the front, bottom door for a label with your model).

They are manufacturer made so they are the same quality as what you are replacing.
A simple twist off, connect the wires and you are done (mind you, if there is a lot of corrosion it might take some elbow grease to get those wires off the old part)

I will point out though, that you probably don't need 4 of these. You need 3 of these (part #3412D024) and one of part #3412D021 (and note the "-26" at the end of the model is the color code, in this case Gray)
The reason is that one of the burners has slightly different connections. I'm not exactly sure I understand the physics behind it, but the lowest BTU burner is different (back left burner on my model).
It's here on Amazon too: http://www.amazon.com/gp/product/B002GUU3H2/ref=cm_cr_ryp_prd_ttl_sol_0
