2025 3.0L I6 K&N Performance Air Intake System

[Scap]

I had a water/methanol injection system on my old ecoboost. Did a great job keeping IAT down because the charge air cooler couldn't keep up.

Did a Google search on the normal temperature range of IAT for these Hurricanes-
For a 2025 Ram 1500 with the Hurricane engine, the normal intake air temperature (IAT) range can vary based on several factors, but some information suggests that values
up to 200°F can be expected when operating under normal conditions on stock maps. These measurements are often taken before the intercooler. One source mentions temperatures reaching around 275°F under boost, indicating that higher IATs can occur under specific driving conditions.
Important Considerations:

• Intercooler: The Hurricane engine is turbocharged, which compresses the intake air. This compression increases the temperature of the air before it enters the engine. The intercooler's job is to cool this compressed air down before it enters the combustion chamber, improving performance and reducing the risk of detonation.
• Location of IAT Sensor: The IAT sensor's location can affect the measured temperature. If the sensor is located before the intercooler, the temperatures will naturally be higher. If it's located after the intercooler, the temperatures will be significantly lower.
• Operating Conditions: Factors like outside air temperature, engine load, and driving style can all influence the IAT.

In summary, while temperatures up to 200°F are considered normal before the intercooler on a 2025 Ram 1500 Hurricane engine under typical operating conditions, higher values can be seen under heavy load or boosting

There are probably 2-4 sensors tracking IATs along the intake track. There were 3 on the 3.5 EcoBoost. I could read all 3, but had to do some experimenting unplugging them methodically to find out which was which.

IAT2 turned out to be post-intercooler & the one to monitor. I do not know if that is universal.

In the Ford’s case, timing happens and de-rating starts to occur when IAT2 hits ~125, and you’re really hurting by 170.

Pre-intercooler temps may have caused false alarm in the discussion here, e.g. if the numbers discussed above are pre-intercooler then the issue may not be as bad as thought.

Would be really good if someone could identify and confirm which PID is a post-intercooler reading.

Still, if it was the same sensor with both intakes it still tells us something. That the open “cold” air intakes are hotter than stock. We just don’t know if that in itself is a problem. Though I’m generally in favor of air being cool as possible.
