Test Results
Stock Intake
- Elevated ambient air temp 17.7° F
- Lowered air pressure 6.8%
- Combined result: air density 90.2% of ambient
Banks Ram-Air
Replaces the stock setup with new housing, filter with 7.5” outlet, lid & ducting system made of
cross-linked polyethylene & polypropylene, all the way to the inlet of the turbo compressor. Inlet to filter
housing is sealed to the fender air duct with open-cell foam.
- Elevated ambient temp just 12.3° F
- Air pressure 3.9% lower than ambient
- Combined result: air density 93.9% of ambient
Banks Ram-Air
with optional Super-Scoop
- Elevated ambient temp only 7.0° F
- Air pressure only 2.8% lower
- Combined result: air density 96.0% of ambient
- The best temperature preservation of any of the 9 systems tested
- Highest overall density of the 9 systems tested
- Delivers enough density improvement over stock to increase the power output 28 more hp at the same EGT!
AEM Brute Force Intake
Replaces the stock setup with an aluminum tube, dry filter & a sheet metal heat shield. Filter has a 4”
outlet which mates to the aluminum tube.
- Elevated ambient temp 52.6° F (2nd highest increase of the group tested)
- Could be attributed to the aluminum tube transferring underhood heat into the intake air
- Lowered air pressure 1.8%
- Combined result: air density 89.5%
- 0.7% worse than stock
- 6.5% worse than Ram-Air with Super-Scoop
- Installation would result in a power loss
AFE Stage I and Stage II
Both systems use a filter with a 6” outlet. Stage I leaves the 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
- 6.9% worse than Banks
- Installation would result in a power loss
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
- 3.8% worse than Banks
Airaid Intake System
Quick-fit system filter mounts to an adapter that mates to the factory inlet duct with a 3.75” inside
diameter.
- Elevated ambient temp 26.8° F
- Lowered air pressure 5.5%
- Combined result: air density 90.1% of ambient
- 0.1% less than stock
- 5.9% worse than Banks
- Installation would result in a power loss
Bullydog RFI
Sheet metal enclosure with an opening toward the factory fenderwell opening. Filter is mated to a section of
elbow tubing that mates to the factory bellows & silencer.
- Elevated ambient temp 19.3° F
- Lowered air pressure 8.3% (only system tested that produced a lower effective air pressure than the stock system)
- Combined result: air density 88.5% of ambient
- 1.7% worse than stock
- 7.5% worse than Banks
- Installation would result in a power loss
Volant Cool Air Intake
Oval-shaped filter housed in an enclosed box with three openings: one at the bottom, one toward the front &
one toward the fender.
- Despite website claims that Volant is the “only true cool air design,” it elevated the ambient temp by 50.5° F—among the highest of the systems tested!
- Lowered air pressure 3.2%
- Combined result: air density 88.2% of ambient
- 2.0% less than stock
- 7.8% worse than Banks
- Installation would result in a power loss
