COLD AIR KITS ARE A GREAT WAY TO IMPROVE THE BREATHING IN YOUR ENGINE ALLOWING LARGER VOULUMES OF AIR TO BE INGESTED. 

What is a multi-throttle body intake system? The multi-throttle body intake systems produced by dbilas dynamic are the successor of the double carburetor kits. As is the case for the double carburetor kits the objective here is also the optimum artificial respiration of the engine. For this reason, instead of the central throttle valve used for the sucking of air to all cylinders in the conventional intake systems, this system only has one throttle valve for each cylinder. In combination with one injection valve per cylinder, this system offers optimum filling of cylinders throughout the whole speed range of the engine. Another advantage of the dynamic multi-throttle body intake systems is that it offers the possibility of using "sharper" camshafts without negative influence on the smoothness of running. Only this method allows aspirating engines to achieve high liter performance. Due to the same suction pipe length and simultaneously the same data a better mixture of the fuel and the asprated air is provided. Consequently the combustion is more efficient which results in an improvement of the fuel consumption in some operation areas. A characteristic feature of our multi-throttle body intake systems is that not only the pollution classification of the vehicle is maintained but also the good running culture according to standard. These characteristics remain unchanged, since all electronic sensors and actuators such as injection valves, air flow sensors or meters, throttle switches and idle control valves continue to be used in the systems. All throttle body kits are pre-mounted and ready to be installed. All kits which are not marked with "R" contain fitting instructions, throttle bodies, intake manifold, airbox, throttle control linkage and all necessary small parts. The kits which are marked with "R" were developed for racing and contain throttle bodies, intake manifold and a throttle control linkage. After conversion an adjustment of the engine management is required. The prices for throttle body kits on this site are not including this adjustment. The specified performance-enhancing refers to standard engines with throttle body kit and adjustment of the engine management.

The Multithrottle Intake system has been used on BMW's since the early 80's and is still in use today. When you peek under the hood of an e46 M3 you will see BMW's factory M division Multi throttle intake manifold which these applications resemble below. So if you own a 318, 325 and a US version E36 M3 and always wanted the Multithrottle intake manifold for those M/// Motorsport performance gains now is your chance. These units are very durable and able to with stand turbo pressures beyond the plastic versions found on the newer factory cars. The old E30 M3's, M5's and M6's Multithrottle intake manifold was a metallic made design making it more durable. Unfortunatly if your thinking as I did well why dont I go to the junk yard and pull the multithrottle intake manifold off of an old M car and bolt it on to my 318 or 330? The answer is simple it wont line up with the motor the metal was cast a certain way for the M block motor it was designed for. Bugger I know, but know you have an answer and let me tell you these are a great performance to add on to your BMW or to give a rebirth of power to your old BMW.
