The long awaited intake for your E-46 M3 is now available.

After several prototypes and dyno runs, we have an intake that gives you real horse power and torque gains. (Dyno sheets posted soon)

Our kit includes our fully enclosed fiberglass heat shield to minimize engine heat soak and air turbulence. We have also developed our own Air Flow Meter that accepts the screen from your stock air box. It is keyed so that the screen is at the proper orientation to the air mass sensor without any modifications.

Also included is our custom made conical filter made specifically for the M3 application. Our filter uses a gauze material that has deeper pleats which increases the total air filtration surface area, traps smaller (and more) particles, and provides your engine more protection. Also, this conical filter has the convex top that further increases the filtration surface area. At the bottom end, we have incorporated an internal velocity stack that increases air speed entering the intake by smoothing out the airflow (decreasing air turbulence) and thereby, increases performance.

As with all of our intake kits, it is easy to install and requires no cutting or modifications to your car. Typical install time is about 45 minutes and can be done with simple hand tools.

When people ask us how they can make their car faster, we tell them that besides the driver, the first thing you need to look into is improving air flow into and out of the engine. The first part of this equation is of course the air intake - the point at which air is drawn into the engine.

Factory specs dictate a fairly restrictive airbox to cut down on noise as well as emissions. The easy thing to do is to bolt on a free-flowing cone style air filter onto your intake bellows. While the cone filter has more surface area and allows more air in, it's also not shielding the filter element from heat. Hot air is less dense than cold air, so we want as much cold air as we can get into the engine. It's not uncommon for people to actually lose horsepower by bolting on a cone style filter because they get heat-soaked air from behind the radiator.

The solution? A heat sheild. This keeps the hot air out and ducts all the cool air directly to the filter element where it can do it's job. The ECIS Intake system does a great job of utilizing factory engineering with a little extra to bring the best gains. The filter stays behind the headlights where it was intended. This makes it easy to maintain as well as keeps it out of water and debris that can be a problem with other intakes that re-located the filter element into the bumper.

For the money, the Cold Air Intake from ECIS is one of our best products. It bolts on with ease and functions exactly as it's supposed to. You really can't ask for more!
