BMW Intake Parts for BMW 3 Series E46 (1999-2005)

This is a short ram intake and filter kit that will go in place of the restrictive and unattractive factory airbox. Feel a dramatic boost to throttle response and build boost faster by eliminating restrictions and widening the intake track. The Injen RD series is a cold air intake system for the enthusiast craving mid-range power. The intake tube is strategically placed behind the front bumper to acquire colder denser air. Although most of the Injen RD series are a one-piece design several are two-piece designs due to the mass air flow meters. Every Injen RD system is certified or pending by the California Air Resource Board and backed by Injen Technology's limited lifetime warranty.

In 1999 Injen designed the first urethane filter with a built-in velocity stack for added performance. The Injen Technology Research and Development Team calculates each filters mesh and pleat count for each specific application during the development stages. Today the state-of-the-art Ea nano-fiber Injen/AMSOIL performance dry filter provides reliable performance and requires NO OIL. Both Injen Air Filters allow cleaning and durability for 1000's of miles to come.

ECS High-Flow Intake for E46 – Unleash Performance and Induction Sound

Transform your E46 driving experience with the ECS High-Flow Intake, engineered for improved airflow, exhilarating induction noise, and a noticeable performance boost. Designed as a direct replacement for your restrictive factory intake, this system lets your engine breathe freely while delivering the aggressive intake sound every enthusiast craves.

Why Upgrade?
The factory intake system prioritizes refinement over performance, limiting airflow and muffling the intake noise for a subdued driving experience. The ECS intake changes the game by significantly increasing air intake efficiency and enhancing the auditory excitement under your hood. It’s a must-have for those seeking the perfect balance of power and sound.

Featured in Action:
Catch this intake in action on the ECS YouTube channel's "Chasing Down Track Times at Pitt Race!" episode, see and hear the difference for yourself.

Key Benefits:

Increased Airflow: Boosts intake efficiency by approximately 27%, flowing an average of 71 CFM more than the stock system.
Enhanced Induction Noise: Enjoy the raw, satisfying sound of air rushing into your engine.
Factory Compatibility: Maintains the stock air induction track and MAF location, allowing a seamless switch back to the factory airbox if needed.
Premium Design Features:

Constructed from durable, lightweight 6061 and 5052 aluminum with a wrinkle-black powder coat finish.
Includes a 7” oiled cotton gauze ECS filter for optimal filtration and airflow.
Silicone intake boot with improved flow replaces the failure-prone factory accordion boot, featuring provisions for F-connector and Idle Air Control (IAC) valve.
Stainless steel M6 hardware and aluminum brackets ensure a secure and reliable installation.

Upgrade your E46 with the ECS High-Flow Intake for a driving experience filled with power, sound, and excitement. Breathe new life into your engine – order now!

Free-flowing intake featuring a roaring induction noise and increased performance to replace your restrictive factory intake.

Upgrade your E46 driving experience by adding induction noise and increased air flow. Let your engine breath and listen to the sweet sweet intake sounds!

With the factory intake you are limited to a finite amount of air, this leaves your engine under-served and limits induction noise. When it comes to the recipe for upgrading your E46 there are a few ingredients that you must have, power and sound. While you can add an exhaust for a bit more power and sound, the biggest difference you can make is adding power and sound under your hood with a high-flow intake. The factory intake box is also referred to as a silencer specifically designed to lower the induction noise for a refined driving experience, this helped exponentially when selling the cars out of the show room circa early 2000's. We as enthusiasts are no longer interested in subdued intake noise and limited air-flow, we want pure induction noise, we want to hear the air being sucked into the engine as we push down on the accelerator.

Key benefits:

Flows on average 71 CFM more than the stock intake system, a ~27% increase in intake efficiency
Increased induction noise
Maintains factory air induction track
Maintains Stock MAF location, allowing user to switch back to the stock airbox and retain the ECS Silicone boot if desired
