good call on drill and tapping some parts, sadly i hadnt considered that on mine. I recently purchased a tap and die set, might have to use it soon!

I went ahead and added back on the drivers side lower air dam and put a small 2"x1" hole in it to allow some flow to the air filter and have seen more consistent air intake temperatures not exceeding 90' while cruising and a bump in engine temps back around 200. since most of my typical commute is cruising i dont think i will strees the electric fans at stoplights that often. I also was recommended a new route to work that involves more low speed driving at less then a mile difference with considerably less traffic and lights.

The past two tanks since changing the large white air dam havent been as impressive to me as the initial two tanks. i think the new block allows too much air to get trapped and still pass thru the upper grille. I think there will be some lexan in my future.
