aFe Throttle Body Spacer - E82 135i, E9X 335i, E60 535i N54

The aFe Throttle Body Spacer sits between the throttle body and the intake manifold on E82 135i, E9X 335i, E60 535i (N54) models. The machined inner surface creates turbulence in the airflow, providing a better mixture with the fuel spray at each cylinder inlet. The agitated air stream atomizes the fuel in the combustion chamber for a more complete burn cycle resulting in slightly increased horsepower, torque and improved throttle response. Each Spacer is precision machined for each application, ensuring a perfect fit, optimized airflow, and no leaks.Notice of Emissions Non-Compliance. The intake system is part of a vehicle's emissions equipment. Removing, disabling, or altering emissions equipment on a pollution-controlled road vehicle violates federal EPA laws (regardless if it has no effect on emissions). Installing devices or software that trick, disable, or modify emissions controls and monitors on a pollution-controlled road vehicle is also illegal. It has been determined by the manufacturer that this product does not require a CARB Executive Order (waiver). However, because it is part of the emissions system it is not legal for installation or use on any pollution-controlled motor vehicle in any state, province, or jurisdiction governed by, or which has adopted, EPA regulations. Some suppliers will not ship to certain states, requiring extra delivery time. We will advise you of any delays.
