My CPS died last night. I went to O'Rieley's last night and picked up a new one. The one they sell is made by borg Warner and has a lifetime guarantee for $54. The electrode on the end is different than the factory one. Since we know the factory ones will fail, I was glad to see this one is different and with the guarantee, I won't ever have to pay for another. I had recently also put one of these in the E500 I recently bought.
