Well I did some logging for the first time since I installed my headers a while back. Noticed that sitting and idling my IATs were getting to 120+ and then cruising the lowest they were getting was 90-95* at 60mph. Is this from my headers? They NEVER used to be that high. 95* was the highest I saw pretty much year round. I was usually right around ambient temps and usually under when cruising. It's only 77* out right now why are my IATs so high? I have a CAI and it works just fine. My ECT temps are just fine staying right at 190* but what in the hell is causing my IATs to get up so high and why aren't they getting very low when cruising?

 

are your headers coated??

 

yup they sure are

 

damn, that should keep a lot of the heat out of the engine bay... what kind of intake do you have... metal?? maybe its heatsoaking. try wrapping the intake and headers with header wrap.... should insulate everything much better.

 

Outlaw enclosed unit. NEVER been this high before maybe 105* at the VERY highest and that was in 100+ weather

 

what have you changed lately
