BMW B58 High Performance Software Tuning F-chassis M240i 340i 440i X3-M40i

Brand: Active Autowerke


Active Autowerke's B58 Performance Software bundle includes stage 1, stage 2 and stage 2 with super high flow cat tunes! We have an option to include the Femto end user program and cable to enable you to do the software flash. WARNING - when flashing your ECU, it is important that you connect a battery charger to your car in order to provide a stable voltage source regardless of your battery condition and you must remove any sleep options on your laptop. If your car has updated software after November 2019, you must not purchase the Femto option and must send the ECU to us for flashing.

Part Details


Please NOTE that BMW dealers now have the technology to flag your vehicle as having the DME modified even if the flash has been removed and replaced with the stock tune and this may impact your cars warranty. You accept full responsibility for the purchase and use of this aftermarket tune for your vehicle.

 • Unlike multi-layer gauze filters which can fray and release fiber particles into your engine, The Active Autowerke BMW M3 Filter uses two layers of tightly-interwoven cotton fabric. The 3 main benefits to woven cotton are the fact its thinner, holds oil better, and is stronger. Since its thinner, it allows better air flow without sacrificing filtration. The cotton holds the oil more evenly, and the medium is much stronger. Unlike gauze, you cannot wear a hole in woven cotton by rubbing it, and there is no way small bits of cotton can rip off since its interlocked with another piece.

 • Direct OEM like fit with superior quality

 • These filters are coated in steel mesh for extra strength and durability, because of this, Green filters are much more dent resistant.

 • These USA filters offer fully seam welded, powder coated, laser cut steel housing with pre-assembled rubber seals on our intake housings.
