Product Details

The Genuine BMW 13-71-7-521-035 is an OEM air intake resonator boot designed to connect the air filter housing to the throttle housing in the engine's air intake system. This rubber boot plays a critical role in maintaining proper airflow and preventing air leaks that can cause performance issues.

Key Features:

  • Genuine BMW OEM part manufactured to exact factory specifications
  • Durable rubber construction designed to withstand engine heat and vibration
  • Precision-engineered fit ensures proper sealing and optimal airflow
  • Prevents vacuum leaks that can cause rough idle and poor engine performance
  • Direct replacement for worn, cracked, or deteriorated original boots

Over time, intake boots can deteriorate due to heat exposure and age, developing cracks or becoming brittle. A damaged intake boot can allow unmetered air into the engine, resulting in rough idle, poor throttle response, and reduced fuel efficiency. Replacing this component with a genuine BMW part restores proper air intake system function and ensures your vehicle performs as designed.

Thank you ! Easy

Fast and easy shopping

Of 6 other vendors I'd found, every one listed the exact same price for the product. Autoplicity was well over 10% less. Although it's like an instinct for me to shop around & compare prices, I would expect that Autoplicity will be the hands down winner on any & all future purchases. I don't know how they do it...but who am I to question them saving me lots of money!!

I only gave them a 3 star raring on their shipping because I went on their site on Tuesday and the order said it had not been shipped. On Wednesday I received my shipment. The left hand needs to figure out what the right hand is doing. Other than that, GREAT
