i also have an x pipe with one chamber mufflers. will those help get more gains from the cold air intake?
The CAI is a total waste of money. You'll get more out of it by putting a super slick oil in it such as Amsoil Signature Series.
dot 4 in a dot 3 car wont hurt it however dot 3 in a dot 4 car wll
Different weight of the fluid. Just flush your system and refill it with DOT 3. You should be fine. Don't drive around on the wrong fluid, though.
Yeah you wont get much of a HP gain from an CAI alone, maybe 3 or 4 more HP. Now combine an CAI with an exhaust and a custom tune and you will feel a power increase.
1/2 HP if you are lucky. This is an often asked question but CAI(cold air intake) kits are usually nothing more than gimmicks and unless you have more extreme mods done to the intake and fuel systems then you will see NO gain in power whatsoever. Even with those other mods you would only see a very minuscule increase at the very top RPM range with a CAI. Don't waste your money on a mod that will cost you $150-$250 or more and net you nothing in power gains. Go out and spend that money on headers, a slightly bigger MAF(mass airflow sensor) along with slightly bigger fuel injectors, a computer programmer(tuner), etc. Any of these items will actually do something to increase power output. Even with the performance exhaust the CAI is just about useless. You were right in not buying yet until you did other mods like the exhaust but it's still not time to buy it unless you don't mind wasting money. Do more mods then the CAI.
