Build your own air intake filter

Does anyone know what they use for an air intake filter?

Just picked up a cone filter for my turbo Volvo and love the sound and throttle respounce but im pretty wary of stuff getting past the filter itself and into the car.

Would there be anyway to build another filter out of a home furnace filter to accompany this new air intake cone?

I figured a couple layers of a furnace filter would do a decent job of filtering all the bad stuff out of the air before it makes it into the car engine.

Anyone??? or can you tell me what the companies use for filters that make up these cone filters?

Filters like the K&N and Fram Air Hog use a cotton gauze material, and it is a much finer media than a furnace filter. I have been running K&N filters on almost everything I own for years, and havent had anything go thru one yet.

take a nylon stocking or two and pull on top of your filter, secure in place with strong rubber band. will keep a lot of particles away, without imparing air flow. needs to be changed maybe once a year. NO FISHBIN!
drove like this on several cars for yrs. and all my cars run on k&n without any trouble. spray/wash/dry/oil/dry - go for another 50K miles.
