DCI's like BMS/Vishnu seem to be the least restrictive and possibly offer the lightest wastegate duty cycles but there are complaints of heat especially during the hot summer months (in Alabama we have lots of those).

Replacing the stock filter with a drop-in like Macht-Snell, BMS, HKS, etc. seems to help a tad with added boost levels but they don't add the sound of the DCI's and might not be enough for higher boost levels.

The CAI's such as STETT and UR seem to do well with lower intake temps and pretty good sound, decent looks... but then again are they as un-restrictive as the simple 2-cone DCI's (BMS/Vishnu) and how are they on wastegate duty cycles in comparison.

Then there is also price... so ya, I have no clue what I want.

Zeph, there is no argument on whether flow is sufficient on the STETT CAI. I have indeed tested it, posted the results, and dyno'd it. I also logged boost and can verify that indeed there is no boost drop at high rpms verifying that the flow is more than sufficient (i.e. not rise in wastegate DCs). There is no argument here. These are just facts.

isn't there a dyno sheet about afe vs stock air box?
afe loses hp.

[NRG]

Looks: Afe, Injen, DCI.
Functionality: DCI, Injen, Afe.

Geez, seems to be too much FUD going around about intakes.

So far the only facts I have seen via dynos (hopefully tested properly and with untainted results) is that: Injen +10whp, aFe loses power, BMS DCI +10whp run 1 dyno...by run 3: -15whp, and CAI's: +5-10whp.

guys i will be installing my Injen intake hopefully tomorrow. will post up pics and observations.

[-Kley-]

I just installed the Fujita F5 short ram intake. Looks good, sounds good, throttle response is better, and acceleration is slightly better. Overall I'm happy. The cabin noise is noticeably louder during acceleration, but at cruising speeds it's just as quiet.






Picked it up for $250. I had to buy a different collar where it connects to the throttle body since the kit is designed for a 330 and I have a 325. Not sure if it's any better or worse than the AFE or Ingen, just throwing another brand out there. The filter is oil-less and reusable. I like that.

I would definitely go with the UR CAI. Although, that Fujita intake looks very promising - well designed.

I was thinking the opposite on the Fujita. You have flow only to one side of the intake getting flow from the vent, yet the other side is squeezed against an enclosed fender well.

The other thing is the UR is not the only CAI. STETT has a CAI available and I have tested it. The filter on the STETT is also substantially larger.

Ah yea I hadn't noticed that, good point.

I'm actually interested in this wastegate duty also - specifically the UR CAI. I notice my intake filter gets really gummed up which could cause breathing issues. Being that the filter is so low to the ground.. when it rains you can get a lot of muddy grease thrown up around it/on it. I never thought about it before, but I might try a DCI just to see if I can feel a difference.

Also on the UR CAI, I sourced a larger filter - the stock one is small I agree. I just chose it because of cosmetic reasons (liked the chrome look).

That fujita is not for N54.

Hey All,

New to the forum after buying a 2007 335xi Sedan last night.

That being said, the first thing I want to do is get an intake.

I was thinking aFE or Injen.

The afe is only $270 with free shipping on autoanything.com
(use code LOYALTY) for 15% off instantly and then bing.com before July 30 for an additional 12% off.

Injen is just a bit more.

I just want to know what is going to give me more power. Afe advertises gains of 27hp (crank) and they have an install video on youtube that shows promising results...

What are we thinking here?

Welcome to the forums! The good news is you have all the info you need here, but you really should try a search first as you will find huge amounts of info on the intake subject. I think all but the vendors of AFE agree, 27 rwhp is a comical claim from AFE. Of those two, I think everyone here would suggest Injen. If you want a CAI, STETT makes a great product.

[AlpineG05]

DCI, the end.

[Brey335i]

Dinan intake... if you've got the money

better yet, GruppM CAI if you have shit load of flow$$

[Former_Boosted_IS]

You will also find people recommend what they have on their car. LOL!

[Krells]

I would skip the intake and get a tune. Much better bang for the buck and proven results. My butt dyno didn't register any gains from my dci but the tune was obvious.

Injen is further away from the heat and has a great snorkel! It looks sharp and has no shield to restrict air. Both will sound awesome for sure. I wanted the AFE for a while, then I saw where people would buy them, and sell them right away afterward. That is not the case with the Injen! Try to find a used one for sale... its hard because everyone wants to keep them!....AFE's are everywhere!!!!!

just my 2c.

I have AEM cones on my BMS kit.... the dry style are indestructible!!! Perfect for the guy that's always taking their stuff out for dealer service... If I had the extra coin I would go with the Injen... Good luck making your choice!!!

[RoundelM3]

I like my AFE just fine...two cone filters (one for each turbo intake pipe), no sharing. Easy to install, looks and sounds good. Been working great for me for 2 years now. Only thing I'd change is move to the dry filters, because the oiled cotton ones dry out too quickly with the high airflow.

[Tiago@VRSF]

I sell both and I went with a custom DIY dual filter kit. Same performance and I get to spend the extra $200 on something more useful.

[Sigmachimde]

This is extremely confusing. With all of this being said though, I have narrowed it down to the BMS dual cone for $140 and the Injen for nearly $350.

Definitely in a pickle here. Is the Injen worth $200 more or will the performance/sound be comparable among the two?

The Injen will not perform better than the BMS.
