Replace air filter on BMW 135i, 335i, 535i with Helene Performance Streamline SE filter panel

This is super-easy process that anyone can do with with just a screwdriver. This mod covers all BMWs with the N54 3.0 liter twin-turbo engine.

My 2008 BMW 135i was the obliging patient for this demonstration.

Step 1 Locate air box under the hood

Air box is large square box on the top of the engine.

Nice clear Instructable, however I am going to call you on a couple issues issues. 1. You may want to add a step that combines 1.1 The tools that a person would need to complete the job 1.2 Here is the biggie safety. You had your watch and bracelet on while performing maintenance. While it might not have hurt you in instance, it is a bad habit to wear jewelry while conducting any type of maintenance. Ok I'm off my soap box. Again nice ible and sweet ride.
