Having your oil pressure light come on can mean very serious problems. Or it could just be this switch that fails several times over a car's lifespan. By no means should you ignore the warning light but replacing this sensor could be the actual culprit. The other problem with this switch is that oil can leak past its seal. With the oil under a lot of pressure at this point, the oil loss can be a serious concern. It's a simple replacement when doing most oil change work.

This Oil Pressure Switch fits the following BMWs:

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
  • Active Autowerke Gen 7 Intake Manifold w/ Dual By Pass Valve
  • Front Mount Air to Air Intercooler
  • Turbo like speed with linear power delivery
  • Large Fuel Injectors
  • Supercharger Oil Cooler
  • Colder Heat Range Spark Plugs
  • High Performance AA Spec Green Filter
  • Active Autowerke High Performance Software
  • All Mounting Hardware, plumbing, hoses and clamps
  • Proven Horsepower gains even under extreme conditions
  • Installation Instructions included
  • 2 Year Limited Warranty
    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
