This is based on a brand new OEM GM intake manifold. This is also a great upgrade since the factory PCV is known to fail as much as it does. The PCV is located inside the intake manifold and is included with this product. Bolts directly back into stock location. 

The factory casts a "wall" in the exit of each intake runner, well it hurts flow, so we remove it. We also blend the inlet of the intake behind the throttle body because it has casting flash from when it was manufactured. Our Sonic picked up 15whp with no other changes with this intake.

This mod works perfectly along with our tune and valve springs because it will give you a ton of high RPM power. The tune will raise the rev limiter so you can shift higher and the valve springs will keep the valves from floating so you can shift in the higher RPMs.

Fits port injected 1.4L turbo engine only.

If you want to make sure this intake manifold is the last you'll ever have to purchase and avoid the PCV issues that plague the 1.4 engine, purchase our PCV upgrade kit here.
