Well the hoodscope would be a bad location for it because of heat soak on the piping. However, making a custom Intake
that fit out the front grill and sucking in air that way has it's benifits, however it has a lot of downfalls too. The reason that the Intake
is located where it is, is because there are more things to consider than just air temp:
accessibility to debris
accessibility to water
proper air movement through the MAF
it's not just about finding the coldest air. That's why it's in the wheel well.
