AFE intakes?
so I am looking to get a JB4 and an intake but I am a little unsure what I should get because these all look similar. Is it worth going Sealed intake or do I want to go with the regular DCI or the DCI with scoops? I dont intend to track it or anything. Just driving it pretty spirited at times. Thanks
Here are the options.... Also which filter would be better? i dont know the difference (see the options in the links) http://www.**********s.com/aFe-Stage...ckage-335i.htm http://www.**********s.com/aFe-Stage...35i-Z4-35i.htm http://www.**********s.com/AFE-Dual-...-335i-535i.htm |

I run the stage 2 sealed one, not the elite . I guess I can't really say I feel that it makes much more hp but I don't feel like its lost any. I have yet to dyno the car with the intake and ets 5" fmic . The nice thing is if you want you can run the sealed one with the lid off to get that nice intake sound. Little off topic but where in CT do you live?

AFE's DCI dousn't lose power. Intake dyno results should be taken with a grain of salt, because there are way to many outside variables to change the result. What should be looked at is your WGDC value as well as IAT's to an extent (which even then isn't very reliable, because it depends on how heat soaked your FMIC is)
To answer your question, any of the three will do their job. Dry filters will have less flow, but filter more dirt compared to the oiled ones. The sealed intakes will receive cooler air, which in turn will make the turbo's work less than an open element intake which sucks in hotter air. The DCI's flow ability somewhat balances this out however, because it can flow more air (no ducting which brings in restrictions). This means the sealed will bring in cooler (denser) air but less of it at higher RPM's, while the DCI will give you more, less dense air. I would say pick based on if you like intake sound or not, and price |

In defense to AFE they make SEVERAL intakes. So to say they all "lose power" is a little off the wall.
BuraQ found substantial gains at the track and on the dyno using the AFE Stage 2 Elite SI Intake. We've been moving quite a lot of those. It's a great intake cause it's sealed box style and only breathes in cold air, unlike other DCI's. They also have a cold air intake style which is based off the stage 2 elite si, that is a good performer as well but because of the price tag nobody really has it. We've maybe sold a handful of those. Thread starter, if you need any help I'm a PM away. Our AFE intakes are priced extremely competitive if not better then the competition too. |

I got make myself a draft for threads like this for everytime they come up.
A DCI setup regardless if it is aFe or BMS etc will produce more gains over stock intake. However, for the cheaper cost for more gains your turbos will "work harder" to produce boost and they become "less efficient". The reason is because the air in the engine bay is less dense than the "outside" ambient air. Then other problem is having your BMW engine bay to looking like this If your not keeping your car or its a lease, then go ahead and fire it up Sometimes the cheaper alternatives come with an equal exchange ie a compromise depending on what you feel is more important to you. CAI or Cold Air Intakes are exactly what they are. These are the benefits:
Depending on the CAI it can produce near or even more gains than a DCI I am running the aFe Stage 2 Elite SI, and it produced significant gains over the stock intake. Both tests where done in almost 10°F difference with the stock intake tested in the lower temps In the winter weather intake cover can be taken off if your going to be racing and during summer weather cover on. Test above was done with cover on However there is a general consensus, if you are not running more the 15+ PSI stick with the stock intake, just get a K&N filter replacement and perhaps add air scoops Top Gear Solutions has the best deals you will find on NEW intakes |

No the sealed intake is not a dci, it has one big oval shaped air filter.

JB4 Map 1 prompts for 13 PSI, so keep the stock intake, and invest in upgrading your FMIC, then Oil Cooler, then intake, then downpipes (keep your mid catts on if your going cattless DPs. This is IMO) Then you will will be "efficiently" ready to start bumping boost up |

That was enough for me and I returned it the next day. This was years ago back in the jb3 days so maybe they redesigned it. But no where near worth the $250 Or whatever I paid. |

Also, aFe Power makes it very clear that you will not see the gains until after the DME has adapted to the new mod. |
