Premium Carbon Fiber Cold Air Intake System

Dinan High Flow Cold Air Intake System for 1998-2001 BMW 740i 4.4L (E38)

The Dinan High Flow Cold Air Intake System is designed to be compatible with 1998-2001 BMW 740i 4.4L (E38) models. It is sold as a complete kit, and is not created or sold by BMW.

The Dinan intake system is engineered to deliver measurable improvements in horsepower and torque by enhancing the engine's intake airflow. The aggressive design of the system provides a less restrictive intake flow compared to the stock setup, resulting in greater engine efficiency and lower intake air temperatures.

The Dinan intake replaces the factory air box with a cylindrical performance air filter and a carbon fiber intake pipe. The filter is relocated to a separate compartment behind the front bumper and below the headlights, insulating it from engine heat and maximizing exposure to outside air. The filter-to-airflow meter pipe is carefully designed to minimize air turbulence and optimize efficiency.

The latest version of the Dinan intake system returns to its carbon fiber roots, featuring a more premium, showroom-worthy appearance complete with an embossed Dinan logo. This updated logo is a marked improvement over the inset Mylar decal used on the original E38 carbon fiber intake, which was prone to wear and damage over time.

Key features and benefits of the Dinan High Flow Cold Air Intake System:

• Max gains of +21 HP and +20 LB-FT of torque (when coupled with engine software)
• Improved throttle response
• Optimized 4-inch diameter carbon fiber intake tube for minimal turbulence
• Updated, long-lasting Dinan logo for enhanced aesthetic appeal
• Larger cylindrical performance air filter for increased airflow

The Dinan High Flow Cold Air Intake System is engineered to deliver tangible performance improvements while also providing a more premium, durable, and visually appealing upgrade compared to the factory air intake. Designed and built to exacting standards, this kit is the perfect choice for BMW 740i (E38) owners seeking to optimize their vehicle's intake airflow and unlock additional power and responsiveness.
