Amsoil air filter performance

[boosthead]

Has anyone dyno'd before and after replacing their air filter with one from Amsoil, to see if there is any impact on performance?

Do you mean a drop in air filter for the stock airbox? I replaced my Cobb SRI oiled filter with an AEM dryflow and if anything, it may have increased power because it has significantly more surface area. I would think a dry flow filter like the AEM or Amsoil will flow better than stock. May be worth a few hp, but the stock airbox is the restriction because it's like the turbo is sucking through a small straw.

I'm thinking of the scenario you mentioned, replacing a cobb or cp-e filter, for example, with an Amsoil filter. I figure it's splitting hairs between Amsoil and the filters used by the two vendors I mentioned, but inquiring minds want to know.

It won't really make a difference, i had the reg. cobb filter before, put the amsoil, no noticeable change.

Your main difference is going to be how well it captures dirt particles, plus you don't have to worry about MAF sensor getting oil and dirt collection on it. Thats why I went with it initially, plus it fill up the filter area perfectly...

Going to sell mine with the Amsoil nano filter.

The AEM filter I replaced my COBB oiled K&N style filter with is significantly larger and has more filter surface area. I always thought the Cobb filter was too small. I had a larger filter on a normally aspirated car in the past. I'd be willing to bet my AEM filter has 30-40% more surface area. Supposedly the dry flows don't flow as much air of an equivalent sized cotton gauze filter, so it is wise to get a larger element.

Of course the main advantage is not having to reoil the filter. The cleaning process for a dryflow is pretty simple.

I'LL be posting my COBB with the AMSOIL filter later tonight, if anyone is interested.!??

Has anyone here attempted to create an air filter from a normal home furnace filter. I am looking into purchasing a couple of normal home furnace filters and construct different types of filters out from them. If done properly, I believe it will work well however, I do not know if it will work as effectively. Does anyone think that this would be a good idea? I don't find air filters expensive however, I do have a lot of problems at the moment with my Mazda protege and even saving up a couple of bucks would help me out in my current situation.

what size filter do you need, I have a collection of cone filters from years of import cars....mainly all new just been sitting around in my garage cabinet.

Air furnace filters are way too porous. They are designed to trap large particles. The particles that automotive air filters have to catch are tiny fractions of the size particles that could be harmful to home HVAC environment. Think microns, here. The tiny particles that automotive air filters trap can do huge amounts of damage to engine bearings and can be very abrasive to cylinder walls, piston rings and other internal engine parts, if they got through to the intake valves.

In short, don't do it. If you want to save money and you are using the stock air box, just get a K&N drop in. They last a lifetime, are cleanable, reusable and do not have to be serviced except about every 50,000 miles.
