View Full Version : Intake Filter Opinions

01-20-13, 09:27 PM
I currently have a Volant CAI and the filter that comes with it is tiny IMO so I want to upgrade it a touch.

Here is what I have now: http://volant.com/edetail.asp?ID=56&ptype=f


Here is what I'm considering:

Volant: http://www.volant.com/edetail.asp?ID=68&ptype=f


K&N: http://www.knfilters.com/search/product.aspx?Prod=RU-3050


Spectre: http://www.spectreperformance.com/index.php/catalog/air-filters/air-filters-racing-cone/6-mounting-flanges/hprtm-air-filter-6-cone-8-5-tall-blue.html

Spectre also has a 7": http://www.spectreperformance.com/index.php/catalog/air-filters/air-filters-racing-cone/6-mounting-flanges/hprtm-air-filter-6-cone-7-tall-blue.html

All are about the same price (I could sell my current unused one for same as these cost so it will be about a direct swap). Question is any opinions on the better brand or just filter is a filter is a filter...?

I would look at Amsoil EA filters.

I agree.

If you have a Lingenfelter airbox, try an AMSOIL EaAU 6080 or 6081 (http://www.amsoil.com/products/ea_filters/EaAU_Photos_and_Specs.pdf) (1" flange or 0.625" flange). It's FAR better than your typical cellulose filter, based on oil particulate analysis bought and paid for by a fellow CTS-V owner. The 6081 will definitely fit, based on conversations with people that have them--I don't know about the 6080.


Brad (C66Racing (http://www.cadillacforums.com/forums/member.php?u=46628)) is an authorized retailer and will give you a couple of bucks off. While you're at it, ask him about the Preferred Customer Program, which costs about $20/year and is totally worthwhile if you buy more than 3 gallons of oil per year. You might as well pick up 12 quarts of AMSOIL Dominator 10W-30 (http://www.amsoil.com/shop/by-product/motor-oil/racing/dominator-10w-30-racing-oil/) while you're at it.

The Spectre 9604 (http://www.summitracing.com/parts/spe-9604) is a great addition. Also recommend buying an AMSOIL EaPF15 pre-filter (http://www.amsoil.com/shop/by-product/filters-and-by-pass-systems/air/amsoil-ea-pre-filters/) to knock out some of that large diameter debris before it screws up the delicate layers in the EaAU 6081.

(BTW--if Brad's inbox is full, I've got his email address.)

You can always just sign up for the preferred customer program on the Amsoil website yourself (or even become a dealer for about the same price).

I've often debated installing a larger filter as well... thanks for the info
