This replacement gasket from Elring is perfect to prevent any further oil leaks.

  • Valve cover gasket
  • Spark plug seals

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

Includes the head gasket.

Sometimes you have to take the cylinder head off of your vehicle to diagnose problems, have it rebuilt, or replace a faulty head gasket. It tends to be a fairly labor intensive job, so anytime you can make it easier is definitely helpful.

When it comes time for reassembly, one of the biggest problems is finding quality gaskets and seals. Turner has your solution with this cylinder head gasket kit. With so many gaskets that are one use only to replace, getting them all done at the same time can be made harder by not having everything you need. With the proper, high quality gaskets, your reassembly will go much easier with no need for trip after trip to the local auto parts stores. Intake, exhaust, downpipe, valve cover, and in some applications valve seals will all help to get your engine into top condition.

When it's time to put everything back together, there are some things that should not be overlooked. Most cylinder head fasteners found on European automobiles are a one time use or stretch bolt. To be sure that everything is tightened down properly, it is important to replace them to get the proper torque reading and ensure the longevity of your repair.

Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!

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
