Hot engine compartment

After running my truck for just a few minutes, the hood is too hot to touch. Lifting the hood while running I notice a super hot stream of air towards the front of the engine shooting upward. Its been almost 100 here in FL but I have never felt that type of heat from an engine. I have only had the truck a few weeks so not sure if it was always like this. The black plastic from the air filter and the engine cover are scalding hot. The temp gauge reflects normal, just looking for opinions before I take it to the dealership and the try to tell me it is normal. If it makes a difference its an 07 with 4.0 ltr and a K&N air filter. I plan to check the filter this weekend maybe it needs a cleaning? Any ideas/suggestions?
