I have to replace mine almost once a year.
As soon as I see excessive black smoke and loss of power......I spend the $300.00 or so and replace it myself in about 20 minutes. Bingo, she's good for another length of time!

Just a word of caution for those who own CM870's out there ... Unplugging your EGR and not having the ECM re-programmed properly for it can make for a lot of excess turbo temps.

Once a year? --- You got a pyro gauge on the Manifold like in my videos? --- Sounds like it is exceeding 900 degrees to me,.. that or you are not letting it cool to below 400 degrees before you shut it off.

Just some thought on it... Rawze
