I noticed on Sunday morning that my Air Charge Temps were going up to 30 and even high 40s when in slow traffic or at traffic lights but then when running and even under hard use they were down in the 10 to 20 deg range with ambient temps in the 10 to 16 range for the day, I had a good think and then realised that my air filter was directly above the rad so I played around with the filter location and now it sits well in front of the rad, right behind the grill, you can see in the pics above that the grill is actually being pushed out a little on the passenger side, now the temps are much lower...it was just heat soak off the ally rad.
