The first step was to remove all the factory intake parts including the GM airbox and our MagnaCharger intake tube. We didn't toss anything, since a few of the connectors and grommets will be reused to secure the new ADM system.

Total time for the complete install was a leisurely two hours, and everything we needed to get it done came in the JBA boxes.

Here are all the main players included in ADM Performance's airbox system. In addition to what's shown here, there's a plethora of bolts, nuts, clamps, and various installation widgets. The best part is that it fits cars with factory intakes as well as those with Magna Chargers affixed. ADM also offers a full race version that allows for even greater airflow, but is a bit more work to install.

The ADM Performance kit came with very detailed installation instructions, so we're not going to give you a bolt-by-bolt description of how it goes in, just the highlights. Per the instructions, we installed the MAF into the 6061 4-inch intake section.

After installing some protective rubber strips (red arrow) we installed and bolted together the two sides of the airbox. Also note the wire to the MAF sensor was relocated to the inside of the airbox. This gets the MAF out of the hot engine bay and lets the ECM read cooler temps, which translates into slightly increased timing.

Next, we installed the ADM conical filter and reconnected the MAF sensor. The larger filter and sealed airbox are keys to making more power. After all, the last place you want hot engine bay air is around your filter.

Lastly, we installed the airbox lid. As you can see, the inlet for the washer bottle comes through the lid, which is why we needed to loosen it up first. Once the lid was in place, we snugged up the washer bottle bolts and refastened the inner fender. It looks great and was an easy two-hour upgrade.

We then assembled the air intake tubing, starting with the silicone hose off of the throttle body.

Since we didn't dyno test the car between the headers and the airbox installation, we asked Andy over at ADM what sort of gains they had been seeing from doing just the airbox. The answer was around 19 peak horsepower and 14 pounds of torque-good gains from such a simple install.
