I would look into fitting an inter-cooler if you are really looking for cooler intake temps. Cold are intakes are a drop in the bucket in comparison when you look at the post turbo air temps.

Be careful with grill blocks on those cars. Make sure the radiator and cooling system is running absolutely top notch before attempting. The older cars tended to run hot and then at times the cooling system tries to catch up after the fact especially on hot days, driving up hill, I had a dash mount manual fan switch just in case. I got better results by finding an optimum speed, insulating the turbo exhaust side and making sure the muffler is free flowing. My brothers 1.6L TD muffler had all kinds of soot accumulation when he got his looked at.
