3-5 horsepower
The amount of horsepower you gain from an aftermarket intake varies, on average though you will gain... 5 - 15 HP ...it is VERY rare to see over 15hp from an intake, if someone tells you otherwise I would be cautious.
you wont gain any horsepower, you will just gain more noise
what can be added to gain horsepower to the air intake of a 2.2L Pontiac sunfire?
In diesel engines, yes. In gasoline engines, not much.
5-15+ depending on vehicle and type of headers.
depending on the style of intake, and type of car you can gain up to around 20% hp
Not enough to justify the cost of buying and installing aftermarket cam shafts, at least on a value-per-dollar basis.
5 or 10 horse.
It depends on a lot of factors, and would be difficult to answer the question without more specific details. Performance gains could be from 20-100 additional horsepower.
cold air intake and headers with a more open exhaust like flowmaster should gain you at least 15 to 25 horsepower
how much u lookin too gain?? Catback exhaust, cold intake, full exhaust.
Maybe 1-3 HP and possibly up to 7 with the addition of an air intake system. But every company out there will give you different statistics. If you lower the back pressure too much by increasing the piping in the exhaust system you can expect a loss in low end power.
