If this is a no no please delete with my abject apologies!

 

That Tom's grill I recognize on those middle two. I like that list grill on that white RX300. Could give me some better cooling with something like that. Especially when I plan to put the intercooler down low one day (I plan to bolt mine to the front bumper (metal part), perhaps at a slight angle).
