Jlevi, you did yourself and your company a huge disservice by posting this thread.

aFe intakes for the e60 are absolutely worthless due to heat soak issues because the aFe intake is not fully enclosed to shield the intake from the heat of the engine. You should not accuse other people of providing "misinformation" regarding the heat soak problem with aFe as aFe was unable and unwilling to provide E60.net with any dyno information to refute said "misinformation". This is not "misinformation", it is FACT.

Here are the facts.

1) aFe has a lovely manufacturing facility.

2) aFe intakes for the E60 are not fully enclosed and are worthless due to heat soak from the engine

3) aFe intakes are dyno proven to LOSE horsepower on every model E60.

4) aFe has was unable and unwilling to provide E60.net/5seriesforums.net members with dyno gains

5) aFe is hands down THE most hated manufacturer by members of E60.net/5seriesforums.net

Well said. #5 is absolutely true.

It doesn't matter that the air going into the engine is hot or cold?? Your statement is absolutely laughable.

Of course air intake temperatures matter. Colder intake air has a higher density and therefore, more oxygen. Many/most ECU's pull timing and reduce power when they measure high intake temperatures...this is done in order to prevent pre-detonation. Some cars are extremely sensitive to intake temperatures and lose large amounts of power when intake temperatures rise due to heat soak and/or high ambient temperatures, ie. aFe HOT AIR INTAKES LOSE POWER.

You might want to research the internal combustion engine and its intricacies.

Jlevi, is AFE willing to produce a CAI that is similar to that of ASR engineering? where the intake cone is basically outside the engine bay, right behind the kidney grills where it can be force fed with fresh air into the engine, then I would be willing to try it. I know that the current AFE CAI that I bought doesn't provide any gains over stock, but my car does sound good

Let's say you're a runner.

Do you think you'd do better sucking cold air through 4" diameter pipe, or sucking furnace-temperature air through a sewer-pipe width pipe?

Capacity makes some difference up to the volume requirements of the engine. Temperature always makes a difference.

Anyone considering purchasing an aFe HOT AIR INTAKE may want to read through this thread. aFe intakes for the E60 LOSE HP due to heat soak.

Jlevi, you may want to want to read through the thread. I am sure you missed it as you only come here to make money off our members.

Exactly. That's why people use nitrous. Makes it seem denser and more oxygen can be burnt off. And why run meth on turbos? Why use intercoolers? Cooler air.

AFE should design something with their filter BEHIND the kidney grill. That way, you're getting the actual cooler air instead of heated "cold" air (a great oxymoron right? ). Can even do dual duct. One at the lower grill and one at the kidney grills. I wonder if that's any good.

Buddy you only feeding us bullsh*t.

We have been through the AFE fiasco here.

Move on to another forum, to sell your hot air intakes.
