Well after doing some testing on my Jeep, I come to find out that the AEM CAI was the culprit to my cats overheating. As soon as I put the stock intake back the cats mostly stopped cooking, especially on the hills. I tried contacting AEM about this via email and got no reply from them. Anyone have a problem contact AEM lately?

 

I run an AEM - my cats have always run hot, so far as I noticed - how did you notice yours were running hotter? Use a thermometer?

 

just wondering how that effects your exhaust?

 

There was more of a sulfur smell with the AEM installed and less with the stock intake.

 

interesting, I THINK I remember seeing a cat temp reading for the aeroforce gauge, that would be interesting to test if it does have it

 

I've been running the AEM for a couple of years and never noticed anything.
