Air intake at race speeds - minimal, but a tick here and there helps. The plastic is pretty good and the airflow rate there is quick, so not as big of a deal. The gold stuff is great for radiant heat though - protecting shock canisters from glowing headers, protecting fuel cells from mufflers, etc. We also use a second type of insulation at times that has some air barrier built in that is effective in some other applications.
