Rally Road Productions, Inc. is a team supported by a group of people with great abilities in their area of expertise. From the "web guy" and driving instructor friends, to owners of various machine shops, they have surrounded ourselves with people that can be trusted to create and manufacture quality products. This is the key to ensuring everything that they sell will perform as it was intended. The goal is to increase customer satisfaction and make the customization or performance enhancement of your vehicle a more enjoyable venture.

This oil cooler system is race tested and proven to outflow the euro M3 oil filter housing. Additionally, this particular system uses a sealing mechanism to direct the oil flow through the cooler lines and then through the oil filter.  Other cooler caps do not provide this seal and therefore the external oil coolers and lines act as a "balloon".  The lines and cooler are pressurized, but oil does not flow through them.  Flowing oil means it is being cooled and not just acting as an external reservoir.

Flow testing reveals that the oil cooler cap will outflow the Euro M3 Oil Filter Housing by more than 80% at the same, pressure, RPM, and oil temperature. In the upper RPM range, there is nearly a 100% improvement in flow from the RallyRoad oil cooler cap when compared to the Euro M3 oil filter housing.  This is a massive improvement over OE and is a worthwhile upgrade, especially in engines that see severe duty.

Features:

  • -8AN o-ring ports to provide a leak free fitting without the use of Teflon tape or sealant used by other oil cooler caps.
  • Viton o-rings are used throughout to maintain function and sealing in a high-temperature oil environment.
  • Use of the stock filter cap bolt to reduce cost and simplify installation.
  • An internal sealing mechanism to direct oil flow through the oil cooler and through the filter.
  • 1/8" NPT side port for external oil pressure gauge.

Kit Includes:

  • Oil filter cap with fittings
  • Oil filter sealing ring
  • BMW MANN Oil Filter and gasket

This part fits the following BMWs
1992-1999 E36 323i 325i 325is 328i 328is

Race on Sunday, to sell on Monday. This old saying is indicative of the new Generation 8 supercharger system for the E46 M3. Through countless hours of testing, it has often been quoted that the true test has always been a race environment. What better venue than Brock Yates One Lap of America Race. With a rigorous 7,000 miles to be covered within a week, and to compete against the likes of Porsches, Corvettes, Nissan GTRs, this would be the testing grounds for the new Generation Active Autowerke Supercharger system. The Active Autowerke Generation 8 Supercharger System not only proved its worth by being the highest ranked BMW within the field, but also ranked 1st in its class..

The data and technology that made this winning combination is now being applied in the new Generation 8 of the Active Autowerke supercharged E46 M3 level 1. Reliability and power is needed if you want to be on the podium, and this new Generation 8 will deliver exactly that. Consistent, repeatable runs of over 415 WHP (525 engine horsepower) were also recorded on the Active Autowerke chassis dyno in hot 94 + degree Fahrenheit conditions with humidity in the 60% + range. These run conditions might be considered a deterrent and not really suited, but it is better knowing the horsepower numbers are under such conditions, since higher horsepower numbers will only increase as the temperature falls and the air becomes more dense.

Stage 1 Performance Specs:
Power : 525 BHP @ 7650 rpm
Torque : 335 ft/lbs @ 5400 rpm
Boost Level : 7-8 psi

Key Features:
  • Rotrex 92 Trim Supercharger

    Want even more power? Upgrade to the Stage 2 kit with Larger Intercooler & Fuel System.
    The stage 2 System boosts the S54's power output to over 600BHP and includes an upgraded fuel system (includes two fuel pumps, fuel filter, all new -6 lines, fuel pressure regulator, dead end fuel rail, upgraded injectors and all required fittings). This ugpraded fuel system is a must once reaching these increased boost levels due to the fact that the factory fuel system is simply inadequate at this level. The stage 2 system also use a larger front mount air to air intercooler and the Active Autowerke custom methanol injection system. NOTE: Level 2 supercharger system is designed and engineered to operate in conjunction with the Active Autowerke Water/Methanol system as an integral part of the kit. Reasons to incapacitate, isolate, turn off, or not installing this system can and will void all warranty and related claims associated to the proper function of the specified Active Autowerke supercharger system.

    Stage 2 Performance Specs:
    Power � : � 605 BHP @ 7000 rpm
    Torque � : � 395 ft/lbs @ 5400 rpm
    Boost Level � : � 11-12 psi

    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.
