Air Intake for a 3.0 E70?

[X5X]

Does anyone know where I can find an Air Intake for a 3.0 E70?
I know they make some for the E53 3.0 but haven't come across any for the E70 3.0.

Thanks

Haven't people learned that intake "upgrades" are basically a scam? You let in more contaminants to the motor, for zero to a few HP increases...and more heatsoak if it is a cone filter sitting in the engine compartment.....

It is, however, a perfect mod for people compelled to mod something- anything- just so they can say 'its modded'..

While I have yet to come across a modification to the engine that is worth voiding my warranty, an air intake mod is perfectly fine depending on its intended use.

For someone upgrading to a free flow exhaust and tuned ECM without the use of an increased intake flow would be a shame.

Really? So letting more particulates into the motor, such that you can actually see higher amounts in the Used Oil Analysis is perfectly fine?

Like this?




This mod WILL reduce performance with a "free flow" exhaust (whatever that marketing term means) and a 'performance ECU tune'. This intake will simply be a dog out of the hole when the engine is sucking hot air from the engine compartment.

On the other hand, throw this puppy on a dyno, open the hood, big fans,... sure you'll see 4 hp gain.

But the most important thing is how the owner feels about their car when they open the hood.

I agree that stock is a great route to go...however with proper care and maintenance, there are aftermarket intakes that will suffice...Dinan for example. Unfortunately, Dinan didn't develop an intake for the E70. An intake alone may be useless except for engine growl but coupled with the right modifications, it will make a difference.

As far heatsoke goes, it's a non factor with street level performance, IMO.

Elevated intake air temperature from cone filters can result in 5%-10% power loss just in regular traffic (underhood temperature vs outside air temperature). Lots of data is available.

I'm aware...Even with such a setup, i believe there are reduction kits that allow the MAF to read real air temperatures. Not my preferred setup as there are much better alternatives. However, the E70 N/A V8 is limited on performance modification alternatives to begin with (let alone the 3.0)...unless one goes with a powerhouse tuner but with that kind of $$ might as well go for an ///M.

Perhaps you are referring to a IATS relocate kit? (Intake Air Temp Sensor)

These are not magic, they simply allow you to put the sensor at a location that MORE ACCURATELY matches the temp of the air coming into the engine.

In this thread, the picture is a cone sitting in the hot engine bat. NO IATS WILL FIX THIS! The air is hot, period. You could mount the IATS on the front grill where it would sense cool air, however this is potentially lethal since the DME is being TOLD it is getting cool air, but it is actually getting hot air (lower density) and the motor is in danger.

FYI, the air temp sensor is incorporated into the MAF, so it always measures that temp- the issue is that heat soak from the engine can influence the maf from outside the sensor- heat radiated from the motor to the maf increases it's sensed temperature - hence the maf is measuring the housing or it's own temp and is sluggish and fails to measure the cooler air that is passing the sensor. It is THIS ONE SITUATON that an IATS relocate is designed to fix....
