A strut tower bar is one of the most common and effective upgrades in a vehicle. With the installation of a strut brace, the body gets added structural strength, preventing tower flex and alignment changes during sporty driving or while at the race track. Improve your E46-Chassis BMW with the Karbonius Carbon Strut Brace! Karbonius Composites was inspired by the popular, but no longer available BMW Performance strut bar to create a version of their own. They have designed an extremely strong and lightweight brace that not only adds strength and stability, but also a spectacular eye-catching look. The carbon strut bar is manufactured in prepreg carbon fiber and cured in aluminum mold in an autoclave; while the strut tower caps are 5-axis CNC machined, and includes titanium strut tower nuts. Installation Instructions Product Details: Fits all E46 and M3 Offered in standard high gloss, 2x2 carbon weave Natural anodized aluminum strut tower caps 6 titanium nuts included Very light, only 1100g weight Perfect fitment and easy installation 100% carbon fiber prepreg Cured in aluminum mold and autoclave Controlled break zone Exclusive and numbered piece 2-year warranty NOTE: All pieces are numbered to guarantee authenticity and origin.

This weighted shift knob makes shifts faster and the extra-large globe shape encourages over-palm shifting. The Black Forest Industries Billet Knob weighs in at 8.8oz (250g), about twice as much as a stock knob and a little heaver than the BMW ZHP knob. The heavier knob amplifies the pendulum motion of the shift lever resulting in smoother and faster shift times. BFI has designed this knob for BMW and VW fitments to fit snug on the shift lever and be secured with Allen set screws. They were careful to reduce tolerances compared to universal knobs. The overall height of the BFI knob is the same as stock anatomic knobs (some BMW M/Performance models have a stock knob that is shorter than this one).

Included with the BFI Billet knob is a matching BFI crest shift emblem. A 5 or 6-speed pattern emblem is available separately.

Choose from soft alcantara or perforated air leather with either a silver or black anodized base.

The CSL Airbox is one of the most demanded improvements among BMW M3 E46 enthusiasts. That is both for performance gain and for the sound it brings to the car. On the other hand, it is a laborious, time-consuming, and expensive modification. For those who are looking for a similar sound to the CSL airbox but are not looking for HP gain, we have developed the Karbonius OEM Style S54 airbox. It is a simplified version of the CSL airbox, that, apart from a louder sound from the engine (+12 dB compared to plastic OEM), gives an awesome appearance and allows for easy installation using the stock elbow and MAF sensor. No need to remap! Regarding power increase, we got +4HP in a recent dyno test compared with the OEM airbox. Not really significant considering that dynos can have a 2% margin error. In conclusion, and pending new tests in the future, we can say no significant power increase and no HP loss. NOTES: Need to install with CSL Crankcase breather hose -- BMW # 11157833649) In SMG version, need to install a Genuine BMW CSL SMG Expansion Tank -- BMW # 21532282549 Fitment: BMW M3 E46 BMW Z4 M
