Don't believe everything you read on the internet (except this).  ;)

Seriously, there are two lengths of horns.  The short straight ones are for
high revving race cars with no low end torque.  You don't want to use them
on a street car.  The longer, curved ones are intended for street cars.  If
you choose to go with air horns, those are the ones you want for a street
car.  Make sure you get the filter socks to put over the ends of them.

Personally, I'd look for an airbox from a Euro carbed Alfa.  I think a cold
air supply is a better bet than having air horns that will suck in hot air
from the engine compartment.

YMMV,
