AIH - delete or not?
take a garden hose, turn it on free flowing, and start to kink the hose. How far do you have to kink it before you see a reduction in the output?
Not that the AIH has any thing to do with cold starting ability anyway, strictly emissions. But I also think we should be concerned about the emissions of our pickups and the perceptions that a smoking diesel creates. I would much rather have a clean burning diesel than a smoking one.
"To reduce white smoke during long idle periods at low ambient temperatures, the PCM will activate the intake air heater. Specific conditions must be present before the heater is activated: "
ambient temperature must be below 0 deg C (32 deg F)
engine oil temperature must be below 55 deg C (131 deg F)
vehicle power must be between 11.8 and 15 volts
parking brake must be applied on manual transmission vehicles
the transmission must be on park or neutral on automatic transmission vehicles
glow plugs must be off
ps. clux, if you feel so strongly about not removing it than dont.
by the way ford F650 and F750's dont have them either

..... not touchin' that one ........

I really do hope that frozen hose problem works out ok for you
Parting shot: Isn't there some federal law thingy about removing emissions control equipment?
Don't forget - EPA views ALL stock equipment as part of the emissions control. If they have their way, you won't be able to change the air filter element unless it is a unit approved by them - as if they know what they are doing.
Ford Trucks for Ford Truck Enthusiasts
IF they succeed, expect them to do the same thing with cars and trucks (it will be easier to set these rules in place against the small minority of bike owners first). Then we can say goodbye to custom trucks and hotrodded engines if EPA does what they want to do.

its only prupose is to reduce smoke durning warm up...thats it
SEMA is a very decent lobbying group. Motorcycle aftermarket parts manufacturers are a sizable part of SEMA, so those interests will be at least looked after when it comes to things legislative.

The truth is, they cannot conceive of the idea that anyone would be interested in a vehicle for any reason except transportation. They view us (people who actually like cars, trucks, motorcycles) as mentally deficient and feel the need to protect the world from us.
The reality is, prior to the advent of computerized controls, any hot-rodder that had a decent working knowledge of how engines operated could have tuned engines to produce less pollution than the kludged together piles Detroit sold under direction of the EPA. Oh, and they would have gotten a LOT BETTER fuel mileage and had more power as well.

From the Clean Air Act, Title 2 Part A Section 202: Establishment of standards
(1) The Administrator shall by regulation prescribe (and
from time to time revise) in accordance with the provisions of
this section, standards applicable to the emission of any air
pollutant from any class or classes of new motor vehicles or
new motor vehicle engines, which in his judgment cause, or
contribute to, air pollution which may reasonably be
anticipated to endanger public health or welfare.
3)(A) In General.- (i) Unless the standard is changed as
provided in subparagraph (B), regulations under paragraph (1)
of this subsection applicable to emissions of hydrocarbons,
carbon monoxide, oxides of nitrogen, and particulate matter from classes or categories of heavy-duty vehicles or engines
manufactured during or after model year 1983 shall contain
standards which reflect the greatest degree of emission
reduction achievable through the application of technology
which the Administrator determines will be available for the
model year to which such standards apply, giving appropriate
consider-
ation to cost, energy, and safety factors associated with the
application of such technology.
Same document, Section 203 Prohibited acts
(3)(A) for any person to remove or render inoperative any
device or element of design installed on or in a motor
vehicle or motor vehicle engine in compliance with regula-
tions under this title prior to its sale and delivery to the
ultimate purchaser, or for any person knowingly to remove or
render inoperative any such device or element of design
after such sale and delivery to the ultimate purchaser; or
(B) for any person to manufacture or sell, or offer to
sell, or install, any part or component intended for use
with, or as part of, any motor vehicle or motor vehicle
engine, where a principal effect of the part or component is
to bypass, defeat, or render inoperative any device or
element of design installed on or in a motor vehicle or
motor vehicle engine in compliance with regulations under
this title, and where the person knows or should know that
such part or component is being offered for sale or
installed for such use or put to such use; or
Seems pretty clear to me. Covers any emissions, and any parts on the vehicle to reduce emissions.
