Upgrade your car's vacuum system with the Silicone Vacuum Line, a vital component that significantly impacts engine performance. Engineered to resist heat and contaminants, this silicone hose promises exceptional durability, ensuring prolonged and reliable operation.

Featuring an inner diameter of 4mm and a vibrant red color, this silicone hose arrives in a 9-foot section, offering the flexibility to customize lengths as needed. Damaged vacuum hoses can lead to various performance issues, from rough idling to engine starting problems. Promptly replace worn-out hoses to optimize your vehicle's overall performance.

If you're seeking to eradicate vacuum leaks and enhance the overall airflow of your intake system, look no further than this comprehensive kit.

The M52TU/M54 air intake boots have gained notoriety for their tendency to crack, resulting in vacuum leaks, triggering check engine lights, and causing various performance issues. The soft rubber boots are constantly exposed to high temperatures from the engine, leading them to become brittle and prone to cracking over time. These cracks permit unmeasured air intake beyond the airflow meter, resulting in rough idling, sputtering, or even engine stalls.

This kit offers a solution by providing both lower and upper air intake boots/hoses for a complete repair. Additionally, as a bonus, the kit includes an ECS Exact-Fit High-Flow Air Filter to optimize your vehicle's intake tract.
