R2C PF10544 Black Hex drop in air filter

After reading several people's concern over the porous + oil style of the k&n filters, I came across this non oil high flow style from R2C. I have not been able to find any reviews on it and decided to just ask if anyone had experience with it?

Nissan 370Z Cold Air Intake Systems. (Scroll down some to find the drop in)

I have these on my 370Z, best drop in hands down. looks pretty sick too

I was going to make a thread.... the best ari filter manufacturer in the world finally made a drop in for our Z's Fitment was perfect, and it feels as if they just cut through the air. As far as drop in, this is IT

Hmmm.... I've also been looking to get some drop-ins myself but have been hesitant about oiled ones... these definitely look promising!

GZ3 I appreciate you sharing your thoughts on the filters. I have ordered myself a pair and will add my impressions to the thread.

NP

they are great, lifetime, dry, and maintenance is easy.

let us know how you like them...my brother was highly impressed

Considering getting these with post maf tubes too

Completely stock Z going from oem paper to these R2Cs

Installed these filters this week. Only a few WOT i have been able to pull off, it has been raining like crazy in florida. I would say the sound at idle isnt much noticeable, but as soon as you give it additional rpm you can definately tell. You can hear the air rushing through them were the oem paper would seem somewhat muffled in comparison. It is like taking a big inhale through a clear nose. I would not say it is louder, it is possible it maybe just slightly quieter from the absence of that restriction. I maybe wrong hard to say not listening side by side. I definately have not driven it enough for the ecu to recalibrate yet, so not sure on HP or MPG yet. I am not sure i would even be able to tell of something that might yield a 1% increase. The sound of the air rushing through it though leads me to believe it is flowing a lot better than oem, whatever the ecu plans to do with that extra air we will see. Loving it and would never go back to the oem paper at this point. i would post a followup impression later.

I personally removed the R2C logo in the top left corner. R2C told me it would be fine just be careful of the urethane and media. they also said that they tested it with and without it and were getting 400 scfm. my alien brain wanted to remove it though and not have it in there. it is a thin piece of metal with a dab of glue behind it. you can take a small razor under the urethane if you want and i used a steak knife gently prying in the center and got it off in under 5 minutes each.

Nice. Ill be removing mine too now

Love these air filters

What do they recommend for cleaning interval?

BTW... has anybody tried the R2C CAI system? I searched for posts and came up empty. Pretty impressive power gains (18 hp) and you don't need to remove the bumper to clean the filters. It still has a partial air box which I assume helps keep some of the engine radiated heat out... I was planning to do K&N drop ins until I saw this post.

I just heard back from R2C and suggested I was planning on cleaning mine once a year and they said that would be fine. I also asked about PSI to blow it out with and they said 50-60 PSI or if you had unregulated air to hold it further away from the filter.

If you want a CAI, Stillen G3 or nothing.

Every month i take em out and tap them clean. If too dirty, air pressure, and if its just caked on, ill do mild soap and water. Just make sure they dry completely... This is from r2c

Cool, thanks. I think I'll order these. It sounds easier than messing with the oil on K&N!

you know they are nuclear easy taking in and out, i probably will adopt your method and do a tap on them too

Its a great way to keep em clean all the time. Its crazy how well these filters flow, ive been thinking of dyno time but already put an exhaust so gains wont reflect only

Alright... payday! Just placed my order! Can't wait to drop these babies in!

Add some post maf tubes and your golden!

Nice! I did not realize that R2C made drop ins :tup: :tup:

I've been running their intakes for three years now. I got a set of the black hex filters that I purchased when they released them a while back (maybe ~1 year?).

FWIW, I've never felt like blowing air in/on them cleaned them out very well. So I always wash them in a bucket of water with some Simple Green. Since I now have two sets, I can let them air dry for several days before storing them.

Can't understand why a company would put a logo right there blocking the air flow. It defeats part of the purpose of the better flowing filter!! It is not like anyone is ever going to see the logo anyway. SMH.

Glad to see you came-up with a way to remove it and get the entire benefit of the filter.

Yea that plaque just doesnt belong there. I spoke with r2c yesterday and they did confirm that flow is completely unaffected. Good thing is its very small and easy to take off

Exactly what i do! Except i used dawn liquid soap last time. The filters dry so fast too. R2c ftw

Yeah, been contemplating those... having difficulty justifying another $100 for what most say is a negligible difference at best. I guess I'll see how she feels with the drop-ins and go from there! :tiphat:

there are dynos that show about a solid 5-6rwhp gain. I posted some and jordo did as well as a few others. For me the biggest benefit of the maf tube was the throttle response...the Z was a little boggy at certain speeds, not any more. Seems to just want to keep going.

Cool... Good to hear. I'll check those out.... Might just end up pulling the trigger...

Done. Just placed my order for a pair of Red HPS tubes! :happydance:

They'll really compliment the Black Hex's I just installed tonight!

Thx for pushing me to look into it more GZ3!

NP man, this combo is proven for 10-12 solid rwhp!

how did you like the filters

Only driven her 3 times since putting the filters in but I can definitely notice a difference... a bit more throttle response and it seems to rev smoother

Tubes should be here Thursday!

Installed mine today and the butt dyno shows increase. Filters looked ready for replacement anyways. As for sound, no difference as my catback muffles any sound there is.

I've been trying to buy these and can't find them in stock anywhere. I placed an order over 6 weeks ago and still waiting.

Yeah i placed an order with tunerzstore but r2c apparently had production issues and is still on backorder, was pretty keen on getting mishimoto intake tubes and r2c panel filters

Don't bother trying to order these, you'll be waiting forever. They aren't making them due to a lack of materials. I've been waiting almost two months and just canceled my order.

Well that sucks... :icon14:

That does suck, I was going to order a pair this summer. So are K&N the best option now for drop-ins, since these aren't available?

Yup i was told they are still on backorder too. Uuuhhhh

ive read that the k&n have been known to gunk up the maf sensor.

AFE makes a dry, reusable drop in that flows better than regular paper filters and costs about the same as the K&N.

I checked their site, it says its oiled. Am I missing something?

Search for Pro Dry S filters on Amazon.

Awesome. You have any experience personally with them?
