Im looking for a 3" filter for my cold air intake im doing on my car, are any of the ebay filters halfway decent? I was looking at foam vs fabric ones, im leaning towards foam because theyre easier to clean, but i hear fabric filters flow more. Im not making major horsepower or anything though, mainly trying to keep my motor running clean is all. Im piecing together a cold air intake kit, already have the carb adaptor, now i need a 45 degree bend, a filter, and about a 3ft hose. Anybody know a good place to get a complete kit?

hell HD or lowes, and filter wise it doesnt make much difference. the main reason id ever run an intake would be to make extra space.

Ive got plenty of space already, i just wanna see if i can get any more mileage gains out of my engine, so rather than buying a 10$ fram filter, im gonna spend 20 more and do a whole cold air intake.

Get an K&N there is no substitue for quality. This can happen if you get a ****** ebay one.

When things like exhaust manifolds and throttle bodies are taken into account, only so much extra airflow makes a difference in an otherwise stock engine. Oiled cotton filters do tend to flow ALOT better but it's debatable as to how much of a difference, if any, the extra airflow actually makes. But they accomplish this using oil to catch the dirt. Foam and other 'dry-flow' design filters significantly increase airflow while trapping more dirt and requiring less maintenance. K and N is good stuff but in my opinion overrated as there are now better options out there than there used to be. I had a K and N complete system on my 04 V8 Dodge Dakota and was more impressed when I tried Volant and AEM dryflo filters.
