Get the highly coveted CSL experience with your S54! The CSL intake plenum is your chance to experience the life-altering CSL intake. For starters, after installation, you are left with a completely transformed engine bay. You can try your very best to resist sticking your arm in the massive inlet of the plenum but we doubt that you will be able to hold back. What are you waiting for? Transform your E46 M3 the way you always imagined. #Turner #Turnermotorsport #tms #turnerbmw #bmw #e46 #bmwe46 #bmwcsl #cslintake #csl #tuba #coldairintake #intakesystem #m3 #bmwm3 #s54 #bmws54
