Assembly instructions: How to easily install grill block with zipties.
1. Make a u-bend to the ziptie. If you use high quality zipties it won`t brake even in tight bends
2. Partice the assembly to grill without the block to figure out how to do it
3. Slide Ziptie through the grill block and put it around the mask/bumber grill
4. Straighten the bend(s) you made and put the locking in place and tighten it little bit but leave it loose
5. Install the second and third to the same phase. You should move from one side to another if you have multiple zipties.
6. Make sure its centered and tighten the zipties and cut the exess material off
Note that you need to make sure that grill block wont hit the paint. This means you need lock the grill block in place in sideways and up and down direction. This is possible with two zipties if you drill the holes in right manner, but for beginners I recommend three holes and one ziptie should be in the centre to other direction.
Remeber also to drill 50mm hole in front of the outiside temperature sensor behind the grill. At this video the hole was still missing.
Fuel savings will be over 5% in the winter and in summer you need to optimise the block you climate, but you can still see easily 3-5% savings. This is the cheapest and easiest mod to do and gives best bang for buck ;).

Nice.
What kind of material you've used to make this grille block?
Did you test overall L/100km differences with and without grill block? If yes could you share your results somehow?
Thanks.

@TheRRC84 Its 3mm thick abs plastic. You can carve it with a hunting knife etc. Not with this car but you can find test results from ecomodder forum by using their own search function. When you block your frontal cooling fully your cd will drop 0.02-0.03 units which is huge. In winter you will also get benefits from faster warm up times which also lowers the fuel consumption.
