In your hot environment you should seriously consider an intercooler with a larger exposed face to curtail heat soak. The Helix intercooler has an ambient face 56% larger than stock and and exposed ambient face(the face of the intercooler exposed to outside air above the lower plastic cowl) up to 70% larger than some of the stock height but thicker intercoolers
it also has rounded bars on the ambient and charge side inside the intercooler to aid in pressure drop and airflow direction and a dense offset staggered fin core with 13 charge rows(heat transfer plates) vs most manufacturers 7-8.
Helix is also a direct bolt on with no trimming required on the 335
and there is a group buy going on right now, where you can see the data and pics on it! I also believe Helix may have some units in stock.

Here is a pic of the helix next the Ams 7"(?) please look at the core above the mounting brackets as this is the exposed ambient face above the lower plastic cowl
as you can see some manufacturers make their intercoolers bigger by enlarging them in areas not exposed to ambient air where ours maintains stock geometry!
