AFE intake f85/f86

[UAEX6M]

Hello guys,

Have anyone tried AFE new intakes? Seems like they also have 2 types of them.. not sure if they are better then Dinan, but they are cheaper for sure, Dinan looks better though


Thanks

An intake by itself wont do much, right? Does AFE offer other parts of the system like Dinan?

I saw these too, and wondered if anyone had any experience with them:

On their website, it looks like they also have catted/catless DPs, tuner, and some catback exhaust options: https://afepower.com/nsearch?q=f85

Dinan does look better, but it doesn't seem like an intake does much for the F85/F86, other than maybe some more spooling sound?

Interesting! it also have the dyno and air flow chart
half of the price compare to dinan

after looking close to the AFE intake images, it looks like the intake draw hot air from the engine bay??? there are some open slots on the top and a big hold open facing backward to the engine, thats not good, thats all the hot air trap in!

in other hand, Dinan draw air from the front grill just like the oem does, and that is cold air from the outside

it looks like it is sucking in hot air form the engine bay through those slots on top.

OnFireX5 did a great write-up on his findings. You may find it interesting:

I read that too, very helpful

Website states it draws air from kidneys. I think it has the same design as the stock box. The open slits on the box is to able to hear the turbos. They have other systems for other cars that have similar open designs

I’m probably going to get one and I will provide a write up

Just double look the picture.
Their design integrate the front scoop.
The OEM is separate from the airbox itself.
Good idea.

Post more pictures when you have it.

exactly, the oem box is functional and fashionable. it is sealed and brings in air from outside the engine bay. this seems to suck in air from all areas and i am guessing that is only to improve the sound not the output.

I would wager a ton of hot air is being sucked in through those cutouts.

Do you have the RK intake on yours? I thought I read that on one of the other threads. Curious to know how all the intakes compare. I just wanna be able to hear some turbo spool and not lose any power from heat. Let us know if you go with AFE!

I do have the RK but we had an abnormal wet season and got me thinking of a hydrolock. Everyone says it’s very unlikely but don’t want to be the first one. For the price I wouldn’t mind having another intake for the winter. I had both Dinan and the RK and ended selling the Dinan. I should of kept it for the winter

The rk performs very well and has an awesome sound. Main reason I bought it. The filters get extremely dirty and have to wash them every 3 months. I even ended buying another set of filters since im washing them so much

AFE started from some previous employees at KN. They know filters and induction well. I don’t think the open slits and slot will pull much hot air in. The stock air ram design constantly drives cool fresh air in. The stock air box is designed very well. The filters are not. You will get more performance with a filter that flows better and larger in size. That was Dinan big sell. As other forms posted the Dinan filter design with velocity stock is where you see the big difference

I like the AFE design, their intake tube has been flow tested. It’s worth a shot for me

Tape up the slots to stop hot air or rip off the tape for more noise?

Can't believe I am suggesting a duct tape fix.

FWIW, I ran an AFE sealed intake a few years back on a high E85 content N54, up top hard to tell however down low it was noticeably quicker to spool especially compared to the twin hot air DCI's.

[iconoclast]

if you close off the slots in any way it will not allow air into the afe box as the front is sealed. i really do not understand this system, perhaps a rep from AFE or a vendor of AFE products may chime in.

[pk9394]

I am very interested in this intake as well because of the price. but the description on there website vs the pictures is very unclear! by the pictures the box is completely close except the slot and one big hole on the box. how can it draw air from outside through the kindly grill like they say on there web???

[iconoclast]

Unless I am missing something it can't only if there is a cut-out at the bottom of the box drawing air from below in front of the radiator behind the kidney but even then all those openings pull in hot air:





Look at this massive cut-out in the back of the box:


One could argue that at speed air is being forced in simply by driving and that new air drops engine bay temps but why even bother gambling on that possibility when there are enclosed units or options that draw fresh external air exclusively?

I think the pictures are not showing the true intake design. I’m already talking to them and about to purchase. The big holes could suck in hot air but feel the primary purpose was for sound. I had a Dinan and it didn’t sound much different than stock.

Everyone has different goals. I wanted performance and sound. A sealed box probably would perform better but Dinan is over priced. You are paying for a raised carbon lid and two filters. Almost double the price

Each AFE filter is 12 inches long. That’s significantly bigger than the stock and has airflow on all sides.

Let’s see if I can get a box on soon and I will let everyone know if it’s worth the money

Front facing photo maybe taken too high hiding the cold air intake inlet. There appears to be scoops directing the airflow upwards on the front of the intake?

To block the factory cold air intake off completely and have a large hole at the rear close to the turbos seems completely ass backwards.

Lets see who gets it first and gives us a review

i am out. i am on dinan s2.
