Which filter is better from a performance stand point?


I just switched back to this after a year. Car feels quicker than when I had I just did the switch back to the alta filter 30 min ago.

Yes I do realize that because it was a massive filter I probably didn't gain that much( I thought I lost power actually), I was worried about the oil going to the mafs that's why did the switch last year.

Also, the exhaust sounds like it has consistant rumble now. Instead of every other 10 seconds.

 

negligable...

the only difference i see is filtering ability/quality. i wouldnt worry about the oil too much (as long as its not dripping).

 

You need to make sure to only use enough oil to make the filter surface feel tacky, that is the reason to oil the filter.

Foam will out perform a paper/cotton filter once they get a bit dirty. Foam has a much greater surface area to collect dirt thus it can hold more.

 

IMHO, foam is better in terms of protection, and flow. A wet type foam filter works like your nose... the foam is like the hair, and the oil is like your mucus. Paper filters typically do not filter as well as foam filters to get higher flow, and once they do start to clog, the airflow drops significantly.

 

I personally highly recommend NOT using an oil type filter. Mine got oil all over the intake track and messed up the maf and two other sensors further down the line. Yes, I did remove as much oil as possible before installing it. Replaced the foam/oil filter with an AEM dryflow filter and I haven't had any troubles since.

 

Hmmm...Ic..I just feel like I lost power though with the giant blue filter what is the model # for your aem?

 

Oil contamination farther down the intake line is a very simple matter of too much oil. Not a design flaw.

Foam will always perform better between cleanings.

 

The oil / foam filter debate is like Ford verses Chevy. Both camps can provide mountains of documentation as to why theirs is better . Pick your poison.

 

i'm pretty sure it is aem-21-2029dk but make sure you get the one with the correct size neck for what you are gonig to put it on.



For naysayers, go ahead and put the oil type filter on if you want. I let you know my experience - you can take your chances.

 

Been using oiled foam filters for over 30 years with no problems. Just make sure you don't over oil it (very common mistake)

 

I've only had the filter on for 2000 miles. There's only like 4800mi on my car since I don't drive it when I'm at school or in bad weather. When do I need to oil it ?

 

You only need to clean and re-oil it when it gets dirty. Hard to tell when it needs cleaning when they changed the color to black. Just depends on driving conditions. If you are going to clean and re-oil it just make sure you get a foam filter cleaning kit. DO NOT use the K&N stuff. Motorcylce shops are the best place to get the kit. When you get ready to oil it, use a pair of latex gloves and put the oil on the gloves and then work it into the filter. It is harder to over oil it this way. You only need enough to make the surface tacky, never enough to actually be able to squeeze it out.
