What is the difference between a cheap cold air intake system from ebay and a KN Cold air intake? Is it just the filter? As long as the piping is aluminum there shouldnt be any difference except for maybe the filter itself right? Why is there such a big range is the prices? Am i just paying for the KN name?
kn are the number 1 best air filters they come with million mile warranty and you get the best airflow you can buy a 200 dollar cold air intake for a car or truck and you can see a gain of 10-25 hp
My opinion? The whole cold air intake fad is far more marketing hype than anything that will give you any significant improvement in your engine's performance. Even the lowly Ford Focus has an intricate cold air intake system that draws air from under the fender in front of the driver's door - right from the factory - most later model vehicles do not draw intake air from the engine compartment.
If you plan on heavily modifying your car, you can get the whole system - Piping, filter, etc. If you're just trying to get a little extra kick and maybe a few more MPG you can go with just the filter. You will never see a heavily modified car with the stock air intake. It's more of a supporting mod than anything else, and a good place to start to get more power from the engine.
