Now that BMWs popular S54 engine (found in the 2001-06 BMW M3, 2001-02 MZ3 and 2007-08 MZ4) are getting older, it's important to keep an eye on particular items. One such point is the S54 Vanos oil line. Normally thought of as a worry-free item, it has proven to put the damper on many track days. Rogue's stainless steel braided VANOS line replaces the factory BMW part number 11367837614 (current MSRP from BMW is $128.08!) The high pressure (1200psi) control system of the S54 vanos system is used to ensure responsive and accurate camshaft adjustments. The added complexity of the high oil pressure used on the S54 vanos means more opportunities for failures. Some customers have encountered the high pressure hardline fail at the track, spraying oil all over their engine compartment, ending their day. Rogue Engineering's S54 Vanos Oil Line is built in their Upper Saddle River, NJ facility, and tested to over 3000psi. Using their stainless steel braided hose with the proper banjo fittings, this a direct replacement for the factory line. Like the factory line, the lower portion of the line uses a heat sleeve from additional heat from the VANOS pump itself. Fits the following BMWs: 2001-06 BMW E46 M3 2001-02 BMW MZ3, including coupe and convertible 2007-08 BMW MZ4, including coupe and convertible

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent.  The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories.  These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

Rogue Engineering Power Pullies are CNC machined from 6061-T6, heat treated aluminum and specially coated with a MIL-A-8625 Type III hard coat anodize finish. This kind of anodizing is not to be confused with a Type II cosmetic anodize finish (typical colors such as red, blue, silver, green, etc.). The hard coat anodize finish actually builds a small surface layer on top of the aluminum, preventing wear.

This part fits the following BMW engines:
S54

This part fits the following chassis:
E46, Z3, Z4

The camshaft position sensor is essential for assisting the engine DME by monitoring the camshaft's position. The data from this sensor is key to optimizing ignition timing and ensuring smooth engine performance. Often referred to as the CMP sensor, this component is crucial for the overall functionality of the powertrain. A failing camshaft position sensor can cause a range of issues, including engine stumbling, hesitation during acceleration, power loss, and even starting difficulties or complete failure to start.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code, but not always a check engine light. A misfire code may be related to an ignition coil, but could be from other things as well. ometimes, a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.

RACING SPARK PLUG FOR M50/M52/M54 ENGINES
These spark plugs are recommended by BMW Motorsport for use in their DTC racing engines. We find a slight horsepower increase and greatly increased durability over the OEM road car spark plugs in competition use. We attribute the improvements to the fact that these spark plugs are designed for the high temperatures and cylinder pressures encountered in a racing engine. These spark plugs are a direct replacement and come pre-gapped just like the factory road car plugs.
Please note: these plugs are not for the S54 engine in the E46 M3, MZ3, or Z4 M

Sometimes a bad coil may just be a broken or damaged connector boot. This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.
