Here you can see the muffler adapters and the PVC elbow. The PVC elbow enters the air filter box through a drilled hole. It has a smaller diameter PVC tube inside so it can make a good seal. Also it has silicon to assure a good seal. The wire seen in the elbow acts like a pin so the engines vibration and movement doesn't pulls out the steel tube.
The original air intake is blocked with a plastic cap, so all the air has to pass through the muffler adapters and PVC elbow. Basically, I diverted the air flow path from outside to inside the engine bay.
The aluminum sheet forces all the surrounding air of the manifold to enter the alternate air inlet extension of muffler adapters and PVC elbow.
