Why the Sinister Diesel Intake Stands Out

At Sinister Diesel, we take pride in crafting intakes that redefine performance, sound, and durability. Here’s why our intakes are the top choice for turbo diesel enthusiasts:

Optimized Airflow for Maximum Performance

Designed with precision, our intakes ensure smooth airflow for peak engine performance. The CNC mandrel-bent aluminum tubing minimizes restrictions, giving your engine the air it needs.

Turbo Sound Unleashed

Experience the thrill of your turbo diesel’s iconic whistle with our open-design intake, enhancing the driving experience.

No Worries About Heat Soak

The thin-walled aluminum tubing dissipates heat efficiently, preventing heat soak and keeping your intake air cool.

Durable Aluminum Construction

Unlike plastic alternatives, our intakes are crafted from durable aluminum, ensuring long-lasting performance and resistance to heat and corrosion.
