AEM dryflow filter for PRL HVI intake

[Nikw91]

Well stated. We have sold thousands of PRL intakes with Green Filter oiled filters (as well as using them on all of our shop cars over the years - 7 Civics and 2 Accords) and have never had any issues ourselves or complaints reported.

What oil do you guys use on the filters after you wash them?

I’m just gonna buy a new one every 10k miles

I am inspecting the maf area for dust every month. So far so good

I have no faith in oiled filters in the long term. Honestly the best play is getting a dry flow filter

the problem with dry flow filters. The better U filter the worse your flow. This is why Cobb and 27won went with very large filters. To make up for the lack of flow. Oiled filters flow excellent but filter like ass after a small while. Hence why so many folks are finding fine dust in the tube past the prl filter. Reoiling isn’t worth it. It’s super messy, easier to create a situation where U have to pull maf and clean it. Just swap the prl filter every 10k miles

eventually someone will find a dry flow filter that’s the same height as prl and as fat and wide as possible

I also noticed a slight reduction in intake noise when switching to the AEM filter, but I didn’t notice any power difference, personally. I did a few data logs with the stock, PRL, and AEM filters and looked at the g/s airflow readings at peak RPM at WOT. they all landed at 280 g/s, give or take 1 g/s. I have no idea if that tells the whole story as I do think there is a small increase on the old butt dyno with the aftermarket intake vs stock. Ultimately, I reinstalled my stock setup for now because the PRL didn’t seem to have caught any dirt that I could see over 8k or so miles, whereas the stock filter had trapped lots of crap in half that mileage. Also, I actually prefer not to listen to the constant sneezing of the blow off valve.
The factory filter pictured has 4-5k miles on it. I guess there’s lots of crap in the air around here!

A cool little intake mod that doesn't affect reliability or filtration is the PRL silicone intake hoses. Same ones that come with the stage 1 intake. They look nice, smooth the airflow, and add a tiny bit more induction noise. They're probably also more durable than the OEM corrugated hoses.

I've only used the AEM filter with the PRL intake, and the intake still increased induction noise by quite a bit over stock. It also does feel quicker to me, though that could just be the butt dyno of course. Just thought I'd mention in case someone is concerned it would quiet down the intake too much.

Also, my OEM filter looked essentially brand new when I removed it at around 5k miles, in contrast to what jtlctr posted above. So your local air quality should be a factor when deciding on a filter, though it probably wouldn't make a huge difference either way as long as you clean it regularly. I could probably run the PRL filter tbh.

When installing my inlet pipe after running the PRL HVI intake for a couple thousand miles, I noticed a light film of dust on the inside of the stock inlet and the maf housing. I decided to change it out to the AEM filter in hopes of catching the finer bits of dust. Didn't notice any change or decrease in woosh woosh noises. I will be taking the intake back off again one of these weekends to install Acuity's shift linkage bushings. I will check to see if there is a decrease in fine dust particles getting past the AEM filter.

Agreed, the PRL intake with AEM filter is way louder than OEM. The PRL intake with the PRL filter is slightly louder however in my opinion.

Thanks for sharing. Looking forward to your results. This guy on Instagram has been doing a series of homemade tests on various aftermarket filters. The Aem dryflow did very well according to his test!

Awesome page! 99.5% filtration for the AEM is insane good!

Interesting! Another alternative I used with my PRL carbon fiber intake was aFe’s Takeda PRO Dry S air filter. I know when it comes to dry synthetic filters, AEM and aFe Power are one of the best options out there, with K&N following closely behind.

OEM filters are obviously still the best since they’re usually around 99.98% in effective filtration.

Do you have the part number for the AFE filter you used?

Hi! Did you ever get a chance to check how well the AEM filter is working?

I dont think thats a dry filter. If those are the correct dimensions the following link is the dry version.
