What is the Elford Throttle Spacer?

“Air chamber volume”
“Highly efficient air intake with increased flow velocity due to venturi shape”
“Elimination of steps in air tunnels”

By optimizing the above three elements, the sluggish accelerator response in the “starting” and “intermediate acceleration regions” peculiar to vehicles equipped with an electronically controlled throttle is eliminated, leading the vehicle to a linear acceleration state.
At Elford, the thickness and shape of the spacers are determined not only by dynamo tests to match the characteristics of each engine, but also by focusing on the “physical effect”, ease of riding, and good feeling. Therefore, we conduct tests with various thicknesses and use the spacer thickness that yields the most well-balanced results as our product.
In this way, it is a handy soup-up part that improves the engine delivery rate of intake air and makes the car a little more energetic.
That is “Elford Throttle Spacer”.

Throttle spacer

(1) Spacer thickness
The spacer’s thickness increases the surge tank’s capacity, and the amount of air required for combustion increases. Thus, the throttle valve opens when the accelerator is turned on, and the amount of air rushing into the engine increases, improving the accelerator pick.
(2) Venturi effect
It is easy to understand that when you squeeze the water hose with your finger, water comes out vigorously. The principle is the same. By narrowing the middle part a little, the pressure is increased, and the air is vigorously sent into the engine.
(3) Eliminate steps in the air tunnel
By matching the diameter difference between the genuine throttle body and the intake manifold through the throttle spacer, there is no step in the air path, and it is possible to flow the air more smoothly.
The thickness and shape of the spacer, which are important, are tested with various specifications, and the optimum type is selected for each vehicle type. Not only dynamo tests but also repeated actual driving tests are conducted, and in addition to numerical values, he pursues products that are particular about “experience effects” and “comfortable driving feel.”
