Product review (5 stars): The flat design looks like it should last longer
oem replacement costs $80.00. Don't waist your money! This ignitor arrived very quickly, extremely well packed. It bolted on with no problem and worked perfectly. I had to adjust the mounting flange  to move the ignitor closer to the burner so there was no delay in ignition. The flat design looks like it should last longer. The OEM unit I replaced 2 yrs. ago was obviously not worth the money in my opinion.
