BMW Performance Accessories


I have realized that BMW has its additional original performance parts sold seperately for 3.35 or 1.35 which significantly increase the engine output and your car is still under warranty.
Is there any similar parts for the M3 that can increase the engine output without voiding the warranty?
My goal is to have no visual changes but increase the low end torque and shift the overall hp curve upwards. (while keeping the warranty)
