I'm thinking of getting the Stillen intake but I have one concern: I'm not a fan of the oil type filters. I believe that the cone filter suppplied with the Stillen intake is a K&N oil type filter (please correct me if I'm wrong here), but I'm wondering if Amsoil (or anybody else) makes a non-oil based filter that can be used instead.

Anybody have any info? TIA

 

Changed mine to an AEM dryflow.

 

Got a part number? When you were researching an alternate filter did you come across any other brands that would work? Thx

 

Anybody know if there are performance differences between the standard filter and alternative options? Does Stillen recommend against using a different filter?

 

I don't have a PN, just got it by size and my receipt doesn't say. I don't remember the length but the hole is 6". It was only ~$39 shipped.

 

Do you know the Stillen (K&N?) filter part number? If I could figure that out then I could cross-reference it against other filters...

 

does it still have that deep tone? what's wrong with the oil-based filters?

 

I'd just prefer not to have to mess with cleaning it and oiling it. Theoretically you can mess up your MAF sensor if you over-oil it, although I know a lot of people will chime in and say that's pretty rare.

In most cases the nanofiber filters work just as good or better than the oiled filters, and only require a dry cloth to clean. They're also generally the same price or cheaper than the oil-based filters.

 

well i purchased a stillen cai with ztube. it should be coming in this week. does it come with oil? is the filter already oiled?

 

If you measure every filtration medium in the correct [square inch area including the pleat depth*] under the maximum air flow conditions for the engine [ ci/2 x rpm x VE/1728] you will find less than 3/4 of 1 percent variation across oem to any aftermarket.

A 214 ci engine can only consume a set amount ~~ 325 CFM at best.

* iron flat [mash the pleats flat] every sample and measure the area you will be surprised that oem has a larger area than aftermarket,

 

Well, not quite. With the Amsoil nanofiber you use low pressure shop air from the inside to clean, no oil, reinstall.
The AEM need a liquid bath cleaner similar to K&N, then let dry out, no oil.

 

whoa..nice information. did you go to a Filter School or something? i'm not clowning tho.

so youre saying that the OEM intake/filters have better performance than an aftermarket intake?

 

Stillen Replacement Filter part number directly from Stillen

402960L

 

So then what is the point in aftermarket filters whatsoever?

Btw, checked Stillen's website today and it says "Comprised of a high-quality polyurethane intake port, washable and reusable cotton filter element, and STILLEN's signature Aluminum Venturi Ring, the Intake draws air from outside the engine bay."

So apparently it's not an oiled filter. So now the question becomes: is there any reason to use another filter at all?

 

what's so special about the ring on the stillen CAI?
