i have a 2004 chevy silverado and i was wondering wut is a good type of cold air intake to buy?? and does that increase hp and mpg??
vinegar may take away the green corrosion , how ever keep an eye on the rest of the pipes after the joint
ok i have a 97 5.7 chevy short bed 4X4 I put a kn air filter in Got a mild power increase but mileage stayed at 14.7 Then i changed it over to synthetic oil and got another small power increase but the mileage stayed the same You can improve it a small amount but in the end if it was such a good deal chevy would have done it They are under great pressure to get gas mileage and besides if their truck got two mpg more than the competition it would be a great selling factor
When someone asked me a question I answer by the following. I think of all the answers and I put them in a circle around me. I look at all the possible answers from all directions. This is a little complicated to explain. Cold air intake can be a benefit in some situations. At a point the colder the climate the less benefit would be derived. This would be when a diverter would be used to redirect air from a warm air source such as the exhaust manifold. This would be to facilitate improved cold weather warm up. Vehicles that use this system vary but also may use cold start injectors and temp. and or hot wire potentiometers, along with the computer and other sensors, to adjust air flow and fuel for optimum operation. Vehicles that use a potentiometer and an air gate, usually have a cold air intake system. Cold air is directed across a hot wire or hot plate and signals are sent to the computer. The computer monitors the recorded difference in the air that crosses through the plate or wire and makes engine adjustments. It would be my opinion that cold forced air would be of greater benefit than just cold air. The difference would be that the air intake would run to the front of the engine bay instead of maybe the inner fender. It would usually run to the top of the radiator or core support so that the cold air is directed to the engine by force. The faster a vehicle travels the more force air has when entering the intake. It is simple to see if air is directed to the engine by cold air, from the engine bay, or forced cold air. Most systems that use cold air also used forced cold air. Trivia: cold air(ram air) and forced cold air(tunnel rams) have been around a long time. To answer your question: If a late model vehicle is not equipped with a cold air intake system it would not be of any significant benefit to alter it, and may, depending on the system, be a disadvantage, especially when the engine is stock. i
I would go with something from K+N. They make quality parts and installation is easy and painless. Plus it has a lifetime air filter that just needs cleaned and re-oiled every once in a while. However, I don't feel that those intakes are true cold air intakes because they don't draw air from an outside source. I do remember watching an episode of Trucks( or something similar) on spike one morning and remember them installing a true cold air intake system in a truck similar to yours.There is a kit that is an actual cold air intake. This kit has a new air intake tube, air filter, air filter box, and it also included a scoop like piece that connected to the filter box and was mounted below the front nose or bumper of the truck to draw in outside air. Sadly, though, I forget what the name of the kit was. It was, however, also fairly simple to install, which makes it number one in my books. As far as HP and MPG goes, I'm almost positive that both will be increased. Most manufacturers state the kind of gains you will receive in order to advertise their product.
