AFE Air intake system

[zayzay]

Does anyone own an AFE air intake system for their 1M and if so, which one do you recommend to purchase from AFE power? Also, if you do own one, do you feel any substantial gains in horsepower and torque?

[mikewills]

I belive Dan Parker has it...the one with the two conical filters.

[zayzay]

do you have a part number?

[mikewills]

I believe it's this one, but please don't quote me. They also sell the intake scoops. Just run up your post count to 5, then PM Dan Parker.

Do a Dual Cone Intake or copy "Mr. 5 Intake".

No need for this.

The dual afe filter is about 3/4 down this page. I did the scoops as well. They have to ram a lot of fresh air into the filters. You can hear the turbos quite a bit more and the quality is top notch. I haven't dyno'd the car with them on so I'm not sure if it makes power but looking at the design I suspect it is an improvement.

I just purchase the afe cold air intake system. do you actually feel a horsepower gain when driving the car compared to stock?

You do notice it a little bit power wise but it really makes a difference with a tune and other power modifications as the N54 bottle necks at the intake. It also has more induction noise. We sell aFe products as well. Also, if you are in that area you might as well replace the charge pipe before it pops off. The OEM plastic piece is pretty poor.

whats everyones view on which is better? single larger filter or dual cone setup?

Dual cone has the most surface area and therefore the least pressure drop across the filter.

Curious what do you think about potential for heat soak with this setup? It looks like the AFE setup you're selling covers the top of the filter which seems to be a better design than the open top version some others are selling. The open top version has two filters vs one though. Care to discuss the adv/dis adv of the two setups?

Also, which of the two intake scoops do you find to work better with the complete AFE setup?

I was considering this, anyone else?





But without the long dual intake tubing like this:

aFe makes great intake systems. I would be curious to see how much power this dual cone system added. Thanks for sharing.

just purchasing the AFE system, i am also curious to see if their is a difference in the feel of the car compared to stock without any other modifications.

[Dan Parker]

The car is very fast stock so it's hard to feel the gains a CAI may make. The afe CAI I used has seals at the top edges and appear to press against the hood nicely. With this design I don't see the need for the cap.

[Fundahl]

Do you know how filters work? I can pull up Mr. 5's logs of reduced waste-gate duty cycle with DCI and his custom one when I'm on a real computer. (On phone now)

I will say, pressure drop increases as you increase your turbo rpm. This is why the stock airbox was designed for a set volume and becomes restrictive at higher boost levels, where a higher volume setup (such as DCI) really shines.

That really confirms my believe not to rely on information posted here by others. Do you own research first!

Actually, bimmerworld is $347.99 and HPA is $376.95.

The kit for the 335 includes the intake tubes.

[TunedM2C]

I think this is the best option available but the price could be better.

I have just gone through the 2k break-in period with my 1M this morning and have been running a AFE p/n 54 82002 sealed CAI w/ the scoops since about the 1,000km mark... While I have yet to take it to redline (5,500 is as far as I have gone), I have jumped on it a bit, and it appears to have equal power, with better throttle response. I picked up a little bit more intake sound (turbo spool) but nothing that would be deemed annoying. Since CAI's deliver most of their increased power at the top end, I probably haven't revved it high enough to experience any gains.... It is going into BMW tomorrow to get it's break-in service completed (engine oil and rear end oil change), so after leaving there I will be sure to experience the top end of what this motor can produce.

I think , THINK, I had read back in the early 135 days that there was no difference between these closed intakes versus plain dual cone intakes

did the scoops install no problem? I remember reading on the 135i forums users had problems with clearance/install of the scoops but that was a long time ago
