This will allow a 2.4L cobalt to bolt on a stock LSJ (2.0 supercharged) throttle body onto their LE5 intake manifold. The intake manifold on the 2.4L has a 66.5mm opening but the stock throttle body is only 64.6mm. This makes the throttle body a restriction to airflow. By using our adapter plate, you can bolt an LSJ TB onto your intake. The LSJ TB is 67.4mm and our adapter plate tapers this to match the intake manifold. The 10% larger TB setup will increase HP from 2-7 HP depending on how highly modified your car is. Please select your year so we can include the appropriate throttle body wire adapter.

ECU tuning may be required.

Includes:

• Spacer plate with tapered hole
• Wire harness adapter (8 pin)
• 4 stainless bolts
• rubber o-ring
