are those chrome pancake filters provide any benefits (power, induction noise) over a standard paper filter?
cheers

...specific.

Clone K&N's as well as proper K&N's allow greater flow of air into the carb/engine. Add more fuel and you get more power.

Downside, induction noise goes up. Better off with a stock filter box with added holes for more air.

sorry, i meant these http://www.minispare.....PANCAKE FIL...

In Vizard's book he says that the chrome/mesh filters are good for flow but useless for filtering! A K&N pancake filter is quite good however, but only if used with a stubstack. And like Big Adam says, noise does go up.

thats cool, just wanted to see if it was worth replacing them! cheers

Im running a drill airbox with a drop in K and N filter, less induction noise, lots of air flow

When I was having my RR tune I had those skinny pancakes on and was told they're crap for flow. Just compare the surface area with that of a conical K&N.

A fake K&N would be better, a real K&N better still...

Like mentioned the K&N element in a standard airbox (drill holes) is apparently best for power

Makes sense actually I'd guess surface area of a filter element is bigger than a cone or pancake.

Can you please post an image of your set up? I'd like to know how many holes you have drilled into your airbox and how big they are. Below is a picture of the airbox i have on my leyland, however, just the black box. I don't have the silver and black piece that's attached to the left....not sure what that is. Would it be worth running a nice big hose from the inlet to the front of the engine bay to get a feed of cold/clean air?

 

Edit: I too was considering a pancake filter or ramflow filter as a cheaper alternative to a K & N but if you've had results with a drill piece and a cheap circular filter i think i'll follow suit!
