AFe Stage-2 Charger Hellcat Intake
Hope everyone is doing well.
I installed the AFe Stage-2 Intake on my Hellcat and I am just worried about a few things.
Firstly, the reason I chose AFe was it was cheaper and I was going after the increased whine. I know there is a lot of history here regarding the AFe but it was readily available here and it came with a heat shield. I installed the rain shield + pre-filter.
When I am driving under throttle and WOT the air fuel ratio is between 13-14.5, however when I lift off the throttle and the car coasts it shows 18. I think it is due to the throttle body being closed and a lot of air is in the tube where the MAF sensor is. Will this harm my O2 sensors as it might dump more fuel? What do you guys think?
The second thing is that the IAT with sitting still in traffic for like 20mins went up to 81C with the engine coolant at 100C, engine oil at 111C and IC at 55C. The outside temp is 23C. The stock box with similar outside temp saw 75C. Will it harm the engine in any way or will I get any CEL light? What temp will there be a CEL?
Looking forward to opinions, hopefully I didn't make a horrible choice.

Your temps are normal too in stop and go traffic. I had to do the conversion but 212F coolant temp at stops is normal with the OEM thermostat. As far as the CEL, mine overheated at 250 miles due to a stuck thermostat. If I recall right the warning light came on at 240 or 250F. I could be wrong though. I made a thread about it maybe I mentioned it in there.Thanks.
Any idea about the IATs?

Hi, it was 250 when the light came on http://www.hellcat.org/threads/2016-challenger-hc-overheated-250-miles.15731/#post-363234Could you post the link to the thread.
Good to know.
