Ordered. And sent a text. Messed up my paypal address crap. Thanks cupcake!!
Looks good, but much more heat will enter that intake than stock. A big part of a COLD air intake is the COLD air.
These factors are what play the role of determining an effective intake:
- How much the ambient air temp is raised in the intake.
- How much the air pressure is lowered in the intake.
- And the resulting air density.
I've only seen one manufacturer that measures all of these parameters.
The stock intake filters better than all "aftermarket high flow" filters.
i didnt think that was as big an issue on a turbocharged diesel because of how hot it gets while getting compressed. pretty much the intercooler controls how cool the air charge is.
trying to get bigger chargers to live is waaay more important that air temp. most people dont measure the wear and tear on their chargers due to lack of sufficient flow do they...
This seemed to be common knowledge. There are several good independent tests I've seen, but don't have time to find them for you. Google may provide assistance.
BTW I've seen an instance in which sand was found in a destroyed turbo... in which the root cause was determined to be an aftermarket K&N filter.
Intake temperatures will generally be higher than ambient conditions, but the more the system can duct cool air to the filter and preserve the cool temperature as the air is ducted to the turbo (compare air temps below), the higher the air density will be. In addition, there will commonly be a pressure drop as air travels through the filter and the ducting due to any restriction that is introduced (compare air pressures below). If the design of the system can minimize the restriction and the pressure loss, air density will be preserved.
Stock Intake
•Elevated ambient air temp 17.7° F
•Lowered air pressure 6.8%
•Combined result: air density 90.2% of ambient
AFE Stage I
filter exposed with a sheet metal heat shield.
•Elevated ambient temp 49.4° F
•Lowered air pressure 2.7%
•Combined result: air density 89.1% of ambient
•1.1% worse than stock
AFE Stage II has a fully enclosed housing with an integrated forward-facing scoop.
•Elevated ambient temp 27.9° F
•Pressure 3.0% less than stock
•Combined result: air density 92.2% of ambient
•2.0% better than stock
Airaid Intake System
•Elevated ambient temp 26.8° F
•Lowered air pressure 5.5%
•Combined result: air density 90.1% of ambient
•0.1% less than stock
AEM Brute Force Intake
• Elevated ambient temp 52.6° F
•Lowered air pressure 1.8%
•Combined result: air density 89.5%
•0.7% worse than stock
Note that I stated this was one instance I've seen in person. There are several studies out there you can find on google the good ol fashion way with two hands and a keyboard.
not a factor when it is and has been proven time and time again that they flow more air thus increasing hp..Looks good, but much more heat will enter that intake than stock. A big part of a COLD air intake is the COLD air.

some yesThe stock intake filters better than all "aftermarket high flow" filters.
filtration cant be beat on a stock element.. airflow on the otherhand, yes.proof please?
mr.google air filter hero.. see below...This seemed to be common knowledge. There are several good independent tests I've seen, but don't have time to find them for you. Google may provide assistance.
BTW I've seen an instance in which sand was found in a destroyed turbo... in which the root cause was determined to be an aftermarket K&N filter.
true datNumbers never lie and the hp and tq gains are there.
id be surprised if any highflow cone filter was as good as oem..ya-that's common knowledge about k&n. i wouldnt broad brush every aftermarket intake as filtering poorer than oem.
WHO said this testing was done on a stock truck? I didn't. Not missing anything here, as I'm an owner of a Spartan tuned 6.4.
It appears I'm the only one providing proof in numbers.
It can't be argued that airflow is restricted to an extent when using an intercooler. But intercoolers are effective because they provide air density.
This effect is the same in an air intake, just to a lesser degree.
And the proof of hp and tq you provide is your well calibrated butt in a seat? According to the numbers the only intake that provides a increase in hp and torque is the AFE stage II.
haha no chit...opcorn: Just what I needed at 4:30 on a Tuesday
might aw well give it up bud... he obviously hasnt read all the threads from guys using mikeys intakes in betta...keep reading, junior...
Post factual #s, mademoiselle...
