Select the year of your McLaren Senna:
These genuine OEM-fit exhaust camshafts are designed for McLaren 3.8L and 4.0L twin-turbo V8 engines, delivering both precision fitment and enhanced performance potential.As performance camshafts, they are engineered to increase horsepower and torque, especially at higher RPMs, making them ideal for spirited driving or racing applications. This is achieved through:
Fitment:
Note:
- Higher lift - allows more air and fuel into the engine, resulting in greater combustion efficiency and power output.
- Longer duration - keeps the valves open longer, which improves breathing at high RPMs but may lead to a rougher idle and decreased efficiency at low speeds.
Fitment:
- McLaren Senna 2019-2021
Note:
- As with most performance upgrades, these may affect idle quality and fuel economy, and are best paired with supporting mods and ECU tuning.
- Professional installation is recommended. Always inspect and replace related valvetrain components when upgrading camshafts.
