LOL!!!! SCROLL UP!! I just posted about this problem haha. I clearly warned everyone that once you go past than normal psi on our car, its a risk to the charge pipe. since bmw had only about 8psi stock on the 335i, its build for just that. anymore than the pipe will either rip, pop off or crack. take apart your airbox and check your chargepipe. their made of plastic stock.
