Tech's opinion of cold air intake kit
 
Will a cold air intake pipe on an EFI car meet with Tech's approval, if it is routed the same, and picks up air in the same location as "Stock configuration"? Specifically talking about 1988 Mustang. Searched subject here and saw where a few people said they were using them, but the threads were basically dealing with something else.

I have never seen one on a 5.0 stocker, It seems if it doesn't have an OEM look it probably won't fly. call them and ask.

Very much depends on who you ask on what day. Or you can just install it and go to tech. Have been running my CAI for 6 years with never an issue. It is the same length and ID as the OE tube and air box. The last time I read the rule book, it said nothing about such a kit.

If you call it a cold air kit it would not be legal that implies you are getting air from outside the car. that would be like letting everybody putting hood scope on. In the case you are talking about on a 5.0 Mustang you pull air from the same spot as a stock mustang in the right front fender. if nothing can change then you would not be able to change the mass air meter or take the resonator out of the air box. All other carb cars don't have to run 100% stock stuff above the carb if so no drop bases and have the stock lid on them. I was told you anything past the throttle body was ok as long as you were getting air from the stock spot.

Another question along the same lines. On a car where the stock air box is mounted behind the head light and draws air through the radiator support, can the headlight be removed if you retain the stock air box? The stock rules state you must have one functioning headlight.

No
One has to function but both have to be there.........................

We spend a great deal of time analyzing intake air options with the use of pressure barometers and anemometers placed on various points of the front and hood area.

These smaller inlet sources provide a fraction of air in comparison to what the engine compartment realizes from the core support area, below the front bumper and through the inner fenders when applicable.

A new Challenger receives almost 30,000 CFM at speed from these areas.

The intake tube may work best as nothing more than a cross section to support the MAF sensor, if retained. If an aftermarket tube is legal, there may be gains to be found. The longer the inlet tube and the more transitions it encompasses, the higher the pressure drop and the velocity profile can suffer.

These cars tend to be cooled and face less ambient temperature prior to runs. The key to better performance may be closer to the throttle body rather than what may occur by extending the tract nearer the core support or fender.

On are 2004 cavalier dirt track car on a wheel dyno. We started with a cold air intake that picked up air at the stock location with a K&N stile filter. We would gain 5 HP by taking it off at the TB, to make a long story short we ended up with a straight pipe that was a foot long with a air filter from a 97 chevy PU that lost 4/10th of a hp. this is on a 150 hp 4 cly motor.
