Download 2002 BMW 325I 2.5L 2003 BMW 325I Sport Wagon 2.5L, Eng Des M54, USA Customer Concern: Check engine light on and fault codes stored. Vehicle running normally. Tests/Procedures: 1. Based upon stored fault codes for secondary air system, there is little or no flow of secondary air into engine. Typical causes for this issue are failed secondary air pumps and/or secondary air check valves. Secondary air pump should operate under normal circumstances when vehicle is first started to perform system test. Pump will normally be heard running when standing in front right corner of vehicle. 2. The secondary air pump is located in the right front of engine compartment. A secondary air pump relay located in the glove box is controlled by the engine control module and sends power to the secondary air pump. 3. Air pump can be disconnected and supplied with power and ground at pump to verify operation is possible.… Read More

2004 Jeep Grand Cherokee Limited BODY & ACCESSORIES Speed Control

Download 1. Disconnect vacuum hose at speed control servo and install a vacuum gauge into the disconnected hose. 2. Start engine and observe gauge at idle.

2000-2003 Ford Focus 2.0L Zetec 21-450 COLD AIR SYSTEM Installation Instructions

Download The AEM Cold Air System differs from all others in several ways. We take the inlet air from outside of the engine compartment where the inlet air is considerably cooler than the hot underhood air. The cooler inlet air temperature translates to more power during the combustion process because cool air is denser than warm air. AEM has conducted extensive inlet air temperature studies and we have seen temperature reductions of up to 50 degrees by pulling air from outside of the engine compartment. The air mass flow to the engine is increased because of the increased airflow and reduced inlet temperature, which translates to more power. The AEM Cold Air Systems are 50 states Street Legal (some models and years still pending) and come with complete instructions for ease of installation. Read and understand these instructions BEFORE attempting to install this product. 1) Getting started a) Make sure vehicle is parked on a level surface.… Read More
