 The BMW N54 Inline 6-cylinder twin-turbocharged engine featured in many of BMW’s production automobiles suffers from carbon build up on the intake valves as a result of direct injection. Positive crankcase pressure combined with a common crankcase ventilation system when used in conjunction with direct injection technology leaves intake valves defenseless from oil accumulation on the back of the valves and valve stems.

 The N54 is known as one of BMW's more powerful and tuner friendly engines - however, they are not without fault. As you now probably know the valve cover is one of the weak points in your engine. We recommend you replace your valve cover with a fresh, Genuine BMW valve cover when you start to see oil seeping out of your valve cover gasket. Often times, these plastic valve covers crack and cause a myriad of running issues.

 N54 fuel injectors have a index number which is critical to take note of when it's time to replace a failed fuel injector. The index number dictates on whether fuel injectors can be mixed or not. The fuel injectors in this kit are the most recent version of what's available and can only be installed with other fuel injectors that have an index number of 11 or higher. If the injectors are 10 or lower all fuel injectors will need to be replaced to ensure proper fuel system and engine performance.

 High pressure fuel pumps, or more simply HPFP's, are a common trouble item on N54 powered BMW's. A failed HPFP can cause your car to go into limp mode or in extreme cases will leave you stranded on the side of the road.

N54 Oil Filter Housing Gasket Replacement

If you own a BMW with an N52, N52N, or N54 engine you can almost be assured that at some point you will be replacing the oil filter housing gasket seal. The seal in question is a soft rubber seal that sits in the filter housing and seals it to the engine block. Over time this seal due to exposure to heat and oil will become hard, shrink, and eventually lose its seal. What then results is a nice oil puddle underneath your vehicle originating from the oil filer housing.

 If your BMW has no fuel pressure at the fuel rail it could be due to a faulty fuel pump. This fuel pump and sender assembly is located in the right side of your BMW's fuel tank and provides fuel flow for the engine. With age the electric pump can stop working.  

More Fuel!

If you are running E85 or if you are making more power on pump gas than your HPFP (High Pressure Fuel Pump) can support? We recommend you install supplement fueling kit of your choice.

Charge pipe Water/methanol injection: provides you the means for effectively reducing engine inlet air temperatures and suppressing harmful detonation. This allows you to increase boost and advance ignition timing—without using high-octane racing fuel—It also reliefs yours HPFP from taking the full load of supplying fuel to your engine. 

Port injection is a kit that is installed between your intake manifold and the cylinder head to provide you with more fueling than your stock system is capable of.  It's a relatively easy system to install and does not require any permanent modification to your car.

Clutch Replacement

If your Stock Clutch is worn down or if you are making big power and your clutch is slipping, or the engagement isn't what it used to be, it's time for a replacement. Slipping clutches won't allow your BMW to accelerate properly and can pose problems under a load such as going up large inclines. Also, a worn clutch can cause less precise and engaging shifts. By replacing your clutch you will restore performance and driving pleasure.

Transmission Services

Heat and friction generated in the transmission through the car’s normal and regular operation can result in damage in any of your transmissions components. Many repair issues related to the transmission can develop over time. Keeping up with Transmission Maintenance can offset or delay these issues from developing.

Maintenance Items: 


FLUID – Transmission Fluid eases the impact of heat and friction on many components in the system. This protectant fluid can become saturated with various types of dirt particles over time. 


Filter: The filter traps many particles before they enter the fluid, but some will still get through. Because dirt particles will continue to impact the system, regular fluid and filter changes are essential.
