Comparison points and tradeoffs
When comparing BILLET 2.2L L61 ECOTEC THROTTLE BODY ADAPTER FOR 2.4L LE5 ECOTEC INTAKE MANIFOLDS with other Throttle Bodies options, use this source-backed detail as the primary discriminator: The key here is not just about size; it’s about intelligent design. The port bore is tapered, 60mm on the throttle body side and 68mm on the intake manifold side. This gradual increase in diameter allows for smooth, uninterrupted airflow, ensuring complete expansion of the air as it passes through the throttle body and minimizes undesirable turbulence.
Use this second fact to evaluate the tradeoff: Category: Replacement Parts / Fuel System / Throttle Bodies. A third point to compare across alternatives is: Application note: Precision Machining Fabricated from robust 6061-T6 aircraft grade billet aluminum, the adapter is CNC machined on every side for exceptional dimensional accuracy and a perfect fit.

Product Description
The 2.2L to 2.4L Ecotec Throttle Body Adapter
Optimizing Airflow
This billet adapter allows the use of a 2.2L L61 Ecotec drive by cable style throttle body to be used with a 2.4l LE5 Ecotec intake manifold. This adapter is great for those who want to run the larger 2.4L intake manifold on their 2.2L’s. It is also great for those that want to switch the drive by wire set up to a drive by cable.
Engineered for Performance
The key here is not just about size; it’s about intelligent design. The port bore is tapered, 60mm on the throttle body side and 68mm on the intake manifold side. This gradual increase in diameter allows for smooth, uninterrupted airflow, ensuring complete expansion of the air as it passes through the throttle body and minimizes undesirable turbulence.
Quality Construction

Why Choose this Adapter?
Tapered Port Bore
The transition between the throttle body and intake manifold is critical for smooth airflow. This adapter features a tapered port bore, 60mm on the throttle body side and a wider 68mm on the intake manifold side. This progressive increase allows for a smooth flow and full expansion of the air as it passes through, minimizing turbulence and maximizing volume for optimal combustion.
Precision Machining
Fabricated from robust 6061-T6 aircraft grade billet aluminum, the adapter is CNC machined on every side for exceptional dimensional accuracy and a perfect fit. This ensures a strong and durable piece, capable of handling the rigors of engine performance.
Leak-Free Seal
The adapter is a 1/2″ thick and employs a high-quality o-ring to establish a perfect, leak-free seal. This is essential for maintaining proper intake pressure and optimal engine performance.
A Worthwhile Upgrade
This 2.2L to 2.4L Ecotec throttle body adapter is a versatile and effective upgrade for enthusiasts seeking to enhance the performance and responsiveness of their Ecotec engines. Whether you’re looking to unlock the airflow potential of a 2.4L intake manifold or prefer the classic feel of a drive-by-cable throttle, this adapter is a must-have. Its precision engineering, quality materials, and comprehensive package make it a worthwhile investment for those looking to maximize their vehicle’s potential.
