Almost none whatsoever at low RPMs and maybe 5-10 h.p. at high RPMs.
From 5 to 10 horsepower.
what year
10 horsepower.
about 2 wheel horsepower
The cold air intake may add 5-10 hp to the 335 it was built with.
15 hp
you will get an extra 2 or 3 horse.
nothing unless you reprogram the computer.
270 horsepower 300 with flowmaster duel exhaust, kn cold air intake, and skunk2 cams.
5 or 10 horse.
depending on the style of intake, and type of car you can gain up to around 20% hp
Depends on which cold air intake you install. Some years back, SCC did dyno testing with a wide range of aftermarket short-ram/cold-air intakes. I believe the highest horsepower gains were attained with Injen and AEM. During the warmer months, an advantage of using a cold air intake is to prevent horsepower loss from elevated engine bay temperatures.
