A Cold Air Intake Actually Help?
cold air intakes will claim that they add an extra 15 HP.
This may be true but with our testing, we have not seen consistent
enough numbers to encourage us to back up this claim. This
does not however mean that cold air intakes don’t work.
Where cold air intakes pay off are in engine longevity. By
adding a cold air intake, especially in conjunction with a
programmer, you are increasing the amount of air that your
turbo can take in. This does two things. First it improves
the fuel to air ratio which can lead to better MPG’s.
Second, it lowers the EGT’s which can be very detrimental
to an engine if allowed to get too high.
I Want An Oiled Or Dry Cold Air Intake System?
you think about cold air intakes, there are two main components
to consider. First is air filtration. When comparing oiled
filters to dry filters the oiled will always filter out more
particulate than the dry filter will. The added oil allows
the cotton fibers in the filter element to trap more particulate
matter as the air passes through it. The downfall is that
in dusty environments the oil filters tend to get dirty quicker
than the dry filter will.
component to consider on a cold air intake is performance,
or how much air flow it allows. From the tests that we have
seen, there is no difference in air flow between an oiled
filter or a dry filter, if they are both clean. However, as
we stated before the oiled filter will catch more particulate
and become dirty quicker than the dry filter will. As a filter
becomes dirtier, its performance decreases due to excess particulate
matter restricting the air flow. Therefore, a dry filter will
provide more performance over a longer period of time than
an oiled filter will.
driven trucks we recommend oiled filters, unless the truck
is driven in an extremely dusty environment. We feel that
the extra filtration power added by the oil is worth sacrificing
the 1 or 2 extra horsepower you might get from using a dry
Much Horse Power Will I Gain From A Cold Air Intake?
the years we have seen outrageous horse power claims from
cold air intake manufacturers. From our experience you can
generally gain a maximum of 15 HP from adding a cold air intake.
We aren’t saying that those manufacturers didn’t
actually get those numbers, however we have thus far been
unable to duplicate them.
Cold Air Intakes Cause Problems To My Engine?
are very rare cases where adding a Cold Air Intake to your
engine can sometime cause issues with the MAP sensor in the
truck. However, when this happens it is usually a result of
human error such as over oiling the filter or damaging the
MAP Sensor during installation.
Do I Clean My Cold Air Intake?
your cold air intake properly you should always precisely
follow the directions included with the cleaning kit produce
by the manufacturer of your intake. Generic filter cleaning
kits purchased from a local auto parts store will clean and
oil your filter effectively. However, most of our customers
have a hard time estimating the appropriate amount of oil
to use on their filter. When using a generic cleaning kit
take caution to not accidentally over oil the filter. This
excess oil can cause problems with sensors and can get into
Cleaning My Filter Element, Why Can’t I Spray It Off
Or Blow It Dry?
never use compressed air or high pressure water on your intake.
Using either of these high pressure elements can cause damage
to the fibers of your filter. Damaged fibers will not hold
oil properly nor will they capture all of the particular matter
passing through the filter. If your filter is extremely dirty
you should simply repeat the cleaning instructions provided
by your manufacturer.
I Get An Open Or Sealed Cold Air Intake System?
you talk about the performance of a cold air intake, you must
consider its effects on the turbo. A turbo’s main job
is to compress air before pushing it to the intercooler. Air
is much more easily compressed when it is cold. With that
in mind an open intake allows the turbo to draw in more hot
air from the engine compartment than a sealed intake would.
A sealed intake is designed in such a way that it draws air
through the fender well of the vehicle instead of through
the engine compartment. Therefore, a sealed intake is the
preferred option for performance reasons.
Adding The Air Scoop Give Me Better Performance?
yes the intake scoop will give better performance because
it allows the filter element to draw in cooler air than normal.
However, from our experience adding an Air Scoop actually
causes your filter to become dirtier at a faster pace. This
means you can actually loose performance due to the filter
becoming clogged. We also strongly recommend against Air Scoops
if your truck is driven in areas with high accumulation of

at this time there is no such thing as a dry cleanable filter.
I Clean My Filter With Any Oiled Cleaning Kit?
company designs and tests its filter to run with a particular
amount of oil on it. Therefore, if you purchase a cleaning
kit from a brand, which is different from the filter brand,
you take the risk of putting too much or not enough oil on
the filter. Both of which can cause problems to your intake
I Get a Filter Wrap For My Cold Air Intake?
not necessary to purchase a filter wrap for your intake. We
however, highly recommend the use of filter wraps. Filter
wraps help to keep the larger debris from ever coming in contact
with the actual filter element. When large debris begins to
collect on the filter it begins to have a snow ball effect,
which in turn causes the filter to become dirty much faster.
Using a filter wrap helps to prevent this issue.
a New Cold Air Intake Have a Spot for My Mass Air Flow Sensor?
All cold air intake systems sold by Thoroughbred Diesel are
equipped with a bung designed to hold the Mass Air Flow Sensor.
It True That Oiled Filters Can Damage a Mass Air Flow Sensor?
Mass Air Flow issues we have seen have been due to user error.
During the cleaning process the owner has usually applied
to much oil (usually due to purchasing a generic oiling kit)
and that excess oil has leaked through to the MAF Sensor.
Cold Air Intakes Required with Turbo Upgrades?
of the time CAI’s are required with turbo upgrades.
If you are unsure, you should check with the manufacturer
of your turbo. Most turbo manufacturing companies require
that you have a performance cold air intake in order for them
to honor your warranty. Thoroughbred Diesel always recommends
that you upgrade your intake system when upgrading your turbo
to provide optimal performance and reliability.
