Yes the J.D.M grill has a much more limited airflow than the stock grill. So you will not get as much air to the radiator. And your engine will overheat. And your whole car could catch fire. And your Dad will say, "Neener, neener, neener!" to you. Then you will feel awful.
well hmm, i guess lexus gotcha there haha....but it still doesnt make sense....the jdm altezza is the same car, so do they overheat all the time in japan?? heh
my 2 cents....1) it really depends on the dealer/service dept....some are dicks, and some arent....and dont forget, they cant just void your warranty like that.....they have to prove that whatever malfunctioned was the result of the grill
2) and like IS300Sam said, its an easy mod to swap out, so if you are really worried, just swap it out before services.....
