^^^^ And stock the 335i has even less need for an aftermarket air cleaner system then the 335is.
BMW underrates the 335is so the actual spread is more then the 20BHP in the brochure. The 335i typically dyno tests about 265whp or 305BHP. They advertise the 335i @ 300BHP. The 335is dynos, in my case @ 319whp or 367BHP. They advertise the 335is @ 320BHP
