My first two projects today, both on the grill, 1 for cosmetic, 1 for efficiency.
I took the upper "Tiger Nose" grill off today, it was pretty easy to access however the small little phillips screws holding the plastic on were very tight and took a lot of slow turns.
Here's the before pic
And here's the after
While I had it off for the black carbon wrap I put my stealth grill block on, here it is from behind
And painted black on the inside to hide it
It was pretty cold today, 12 degrees so it wasn't the best day to test it but after a short drive 85 in the city, parked it at idle it would go to 89 then kick back down to 88, did the same thing about 3 times.
