BMW Intake Boots & Hoses for BMW X Series E70 (2007-2013)

Clear BMW chassis

The intake boot provides a pathway for air from the air flow sensor to the intake manifold. On most BMWs the boot is made of rubber with an accordian shape that allows the engine to shift and vibrate. As with any rubber component the rubber can dry out and crack and that can lead to serious running and drivability issues. A crack in the boot means that air is entering the engine that is not being monitored by the airflow sensor. The engine computer relies on data from the airflow sensor to set the fuel mixture in the engine. Excess unmetered air can result in lean condition faults, rough running, misfires, and other performance issues. For misfire and lean condition faults, check your intake boots first.

As an alternative to the original rubber, we also offer silicone boots that are both stronger and last longer with a 4-layer silicone design. Samco silicone boots can also decrease your BMW's intake turbulence and restriction by replacing the accordian design with a smoothed internal surface. Samco boots are also perfect as part of a kit to eliminate the factory traction control system (sometimes called an ASC delete boot).

Turner Motorsport Silicone PCV Hose for BMW M57

Upgrade your BMW M57 engine with our Silicone PCV Hose, a premium replacement for the fragile, failure-prone factory hose. Over time, the stock rubber hose deteriorates due to constant exposure to heat and oil, leading to cracks and leaks. Our solution? A high-quality silicone hose engineered for superior durability and long-term reliability.

To further enhance performance, we’ve lined the hose with fluorosilicone, providing exceptional resistance to oil and chemical degradation. Designed in-house using advanced CAD modeling and 3D scanning, this hose offers a precise OEM fit while eliminating the common weaknesses of rubber construction.

Each kit includes stainless steel hose clamps for a secure, hassle-free installation. Whether you’re replacing a worn-out PCV hose or upgrading for added peace of mind, this premium solution ensures your BMW M57 runs smoothly and efficiently for years to come.

Features:

Direct OEM Fit – Retains factory hose dimensions while eliminating reliability issues.
High-Performance Silicone – Resists heat-related wear for long-lasting durability.
4-Ply Fluorosilicone Lining – Superior protection against oil and chemical exposure.
Stainless Steel Clamps Included – Secure installation and extended service life.
