An easy way to improve the performance of your N54 powered BMW is by removing the stock air box and swapping in this Dual Cone Intake "DCI" from Burger Motorsports. Featuring two S&B inverted cone filters with adapter couplers and new hardware, these easily install into the stock box location, allowing for greatly improved intake air flow. This is great for both stock and modified vehicles, as this allows for greater air flow at all RPMs and removes the air restriction that would normally rob your engine of power.

In addition to increased power, these filters give your engine a more aggressive appearance and sound that any automotive enthusiast will appreciate.

Don't buy into the hype that your car is maintenance-free! It was only free during the BMW warranty period, which simply deferred maintenance. Take charge of the care and servicing of your investment and it will reward you in driving pleasure and in your bank account. Using a preventative service schedule will not only keep your BMW running like new, but will also prevent a more costly repair and inconvenience in the future. Not to mention, complete and thorough maintenance records can add hundreds or thousands to a selling price of a used car and give a buyer unmatched piece-of-mind.

Our approach to servicing and caring for newer BMW models is not radically different than when we opened nearly twenty years ago. The design and materials of some components have changed but that only affects WHEN you should replace something, not IF. Through our own Service Department, and thousands of sales annually, we have put together packages for your newer BMW model that will reinject some life into your car and keep it performing at its peak. We use Original Equipment (OE) or Original Equipment Manufacturer (OEM) parts that we have trusted since we opened in 1993. In some cases, we recommend a performance alternative part that we have found works better, or resolves a design flaw, with the original. So you get top quality parts, first-rate service, and unbeatable expertise.

The LL-01 BMW oil specification marks stringent requirements from BMW that oil must meet in order to receive this approval rating. Still used today in many BMW NA and Turbo engines, LL-01 TwinPower Turbo 5w-30 and all LL-01 approved oils are great for ensuring proper wear protection and low fuel consumption, even during high oil change intervals. When BMW LL-04 oil was developed, it was not approved at the time for use in the US. This was due to the high sulfur and ethanol content in US fuels. Originally used mostly for diesel engines and euro motors, LL-04 demand is now starting to pick up with changes in US fuels such as lower sulfur content since 2014 and thanks to LL-04 and LL-01 being interchangeable/compatible. The slight advantage of LL-04 over LL-01 is due to LL-04's higher ZDDP levels and HTHS ratings. This allows for increased engine protection at higher temperatures and engine pressures. In addition, LL-04 also has a lower SAPS level which benefits direct-injection engines, including all BMW turbo engines since 2007.
