The stainless steel ignition box fit well on my Lynx grill and the new ceramic burner. I replaced an extra ignitor box with the plan of upgrading the second brass burner to the ceramic burner if the new ceramic burner works as well as expected. This new ignitor box still worked fine igniting the flames on the new brass burner too. The only complaint is that the new individual ignitor box did not come with a stainless steel screw. The one in the ceramic burner kit did.
