BMW Intake Boots & Hoses for BMW 3 Series E92 (2007-2013)

Clear BMW chassis

Please ensure your correct model is selected

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).

These silicone inlets from Vargas Turbo are designed to ease the installation of your new turbochargers or improve the reliability of your existing setup. Silicone hose is much stronger and more resistant to heat than the stock parts, meaning that you can build more boost and make more power without fear of your inlets failing. In addition, they don't collapse as easily under pressure. These important attributes make silicone inlets an ideal and necessary upgrade for your turbocharged BMW. Starting in 1978, Vargas Turbo Technologies was built upon the dream of utilizing then-new turbocharger technology to improve the performance of everything from cars to boats. On the cutting edge since the beginning, the company has grown with the industry, servicing diesel and industrial turbochargers. Returning to their hot-rod roots, Vargas has jumped head-first into the BMW performance market, filling a need for high-quality, cost effective turbocharger upgrades for everything from daily-driven street cars to all-out racing machines.
