Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

1999-2000 E46 323i/Ci Stage 1 Performance Package
Peak Power Gain: +17hp / +8ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is made with heat-blocking materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe uses an oiled cotton filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E46 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.

1999-2000 E46 323i/Ci Stage 1 Performance Package includes:
aFe Cold Air Intake (oiled cotton filter, heat shield, intake tube)
Shark Injector performance software

Applications:
1999-2000 E46 323i sedan, 323Ci coupe and convertible

This tube runs from the oil separator to the lower dipstick tube.

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate.

Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable.

This is the replacement for the troublesome oil filter profile gasket on the M50, S50US, M52, S52, M52TU, M54, and S54 engines. The housing is separate from the engine block and in between there is this small profile gasket. The gasket shrinks over time which allows oil to seep out. In our own service shop, it's one of the most common service jobs we perform.

One of the other common leak points is the VAN0S oil line and its seals. Since the line comes out with the oil filter housing anyway you might as well replace the line itself or at least the seals.

On S54 engines (E46 M3, MZ3, Z4 M) there is a flanged head bolt going into the cylinder head, behind the thermostat cover. This holds the left side timing chain guide rail in place and if it's loose or falls out you could have a very serious engine failure to deal with. Make sure to check this bolt while you're replacing the oil filter housing seal. You only need to make sure it's tight. But if it's come loose you may want to replace the seal ring and use a small touch of oil-resistant thread sealer.

The aFe intake is made with heat-blocking materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E46 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.

2001-2006 E46 325i/Ci/Xi/iT (M54 engine) Stage 1 Performance Package
Peak Power Gain: +8hp / +8ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is a cone filter with a heat-blocking shield around it. The larger surface area of the filter, combined with the heat shield, allow more cool air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E46 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.

2001-2006 E46 325i/Ci/Xi/iT (M54 engine) Stage 1 Engine Upgrade includes:
aFe Cold Air Intake (filter, heat shield, intake tube)
Shark Injector performance software

Applications:
2001-2006 E46 325i sedan, 325Ci coupe and convertible, 325Xi sedan, 325iT wagon, 325XiT wagon ( M54 engine only).
