All BBK 2000-2002 Focus throttle bodies are designed to increase airflow and improve horsepower from between 7-12 HP depending on vehicle and application.

BBK are the world’s number one manufacturer of aftermarket performance throttle bodies for late model EFI performance cars and trucks.

All BBK Performance Power+Plus Series throttle bodies are CNC machined from high quality 356 aluminum castings to ensure perfect OEM quality and fit every time. Features like OEM die stamped throttle linkages, double sealed bearings, o ringed throttle shafts and new electronic controlled injection molded plastic gear assemblies for the new modern drive by wire applications, make BBK throttle bodies number one in performance and quality.

All throttle bodies are direct replacements and include new gaskets and detailed installation instructions.

Q. Why is my Throttle body sticking closed near Idle?

A. This condition is sometimes known as "vacuum lock." There is an extreme amount of vacuum pressure on the backside of the plate, and a large pressure difference from that of the front side. When this happens, the throttle blade tends to want to stay in the closed position, due in large part to the intense vacuum pressure created by the engine. Simply using the Idle set screw (gold colored screw which the linkage rests against) to prop open the blade a tiny bit more will usually solve the problem by allowing more air to pass through the opening, thus better equalizing the pressure and alleviating the "lock." Remember to do small increments at a time, maybe ¼- to ½-turn each attempt.

Q. Why does my throttle body whistle? What can I do?

A. Turbulence in the airflow stream can create a whistle. This can be created by sharp edges in the air intake system, most notably when a larger throttle body is used on a stock intake that has not been 'Port Matched.' The air along the outer edges of the air intake system and throttle body hits the "wall" of the smaller intake manifold, creating turbulence that can cause a noticeable whistle. Other trouble areas can be the small vacuum ports and the IAC (Idle Air Control) valve port which may empty into the main bore of the throttle body. If these edges are square enough at the entry point of the bore, it can create turbulence, and the air will whistle passed it (similar to blowing over the top of an empty cola bottle just right to get it to whistle).
BBK offers a 1 year manufacturers warranty against any defects in materials or workmanship. If you feel that the ports of your throttle body are creating a whistle, you can request an RGA number (Returned Goods Authorization number) and return it to us, at which time we will inspect your piece, and further hone as you may feel it to necessary. Alternatively, if you would rather keep possession of your throttle body, and you feel you are adept enough with simple hand tools, you may want to try and hone the ports yourself with fine grit sandpaper. Some customers are adept enough with a small drill or Dremel-type tool to lightly sand the edges down. Be aware though, that any irreparable damages done to the product on the customers behalf cannot be warranted by BBK. If you feel that you are not capable of the task or do not want to risk possible damage, BBK strongly urges you to send the part in under warranty. Be aware though, that further honing the throttle body will not cure any whistling issues if the problem actually lies elsewhere in the system, and if the added airflow of a larger-bore throttle body is only making the problem perceptible.

Q. My throttle body has connections for cables on it that I don't seem to have on my throttle body. Is this the wrong one?

A. Not necessarily. Many times, our throttle body designs will encompass many different models, some of which use slightly different connections than other models. This is especially true of Automatic cars versus Manuals. If you find that you have arms and cable connections that you simply have no use for, you may safely ignore them!

Q. My throttle body seems to have vacuum ports that I don't have connections for. Did I get the wrong one?

A. Not necessarily. Here at BBK, we have discovered that some of the basic design characteristics of our throttle bodies carry over to a large number of models. In order to offer as many enthusiasts as possible a choice for performance throttle bodies, we have gone the extra mile to add certain connections to them that are required for some applications, though perhaps not yours. If this is the case, you must cap off the remaining vacuum ports, so as to avoid possible vacuum leaks that could be detrimental to your performance.

Q. Why doesn't my BBK throttle body have holes in the butterfly like my stock one?

A. The holes in a stock throttle body are there to help fight a situation known as "vacuum lock." When the blades are closed almost fully, and very little air is allowed to creep through, you wind up with a large difference in pressure between the front side, where it is about the same pressure as the atmosphere, and the backside, where the motor is creating a large vacuum against the butterfly. This tends to lock the blade into place. Since the stock throttle body is so much smaller than BBK's, it is much more of a dilemma, requiring holes in the butterfly to allow more air to flow passed, equalizing pressure. Since the BBK throttle body is a bit larger, it tends to flow more air passed its opening, thereby avoiding the need for the holes.
