I have the stock airbox with ribs smoothed out and inside coated in a boat resin, bottom has a 4" opening with a 4" aluminum tube running down to just above the fender-well lining, and a Arid MIT and my IAT runs about 110 in traffic on a 95 degree day. On the move its about 98-105 it really works well. Don't worry about thinking water will get in as I still have the factory openings so even if the tube is in water the least resistant path will draw the air. Kinda like those AEM CAI bypass valves.

 

Andy I'd be interested to see how you routed that tube to the intake. Any help to get cooler air to the filter is worth it IMO. I never removed the plate below my intake either... I really need to take the time to do that.

 

Going up to the air box

How it was routed with the Volant air box.

I cut a 4" hole in the metal plate thats under the intake.

 

if you relocated the IAT to the EGR port. it will heat soak fast from the engine heat rising and the manifold warming up.
but a quick hit on the throttle and it drops fast.

 

Hang on. The IAT sensor is a sensor. If you relocate the sensor it wont change the actual intake temperature of the air, you will just be reading the temp from something else.....

 

im against that aluminum tube, that thing would get heatsoaked like anything! ask me how I know...

 

Thats pretty cool... dunno how well it would work with the K&N open air filter set up though.

 

The stock IAT sensor in the MAF is junk...

 

Pretty much what he said. You can get way better sensors that are more accurate and are alot faster, unlike the stock MAF IAT sensor

 

ditch the aluminum tube for a plastic one. or heat wrap the tube to prevent some heat soak?
