Hello everyone! I’ve successfully completed the Secondary Air Injection (SAIS) mod and created a three-part video series documenting the process.

Part 1 covers the removal of the intake manifold.



Part 2 covers how to drain the engine block.


Part 3 covers how to replace coolant bypass gaskets, replace brittle connectors in the intake valley, choose the right filter for the SAIS pump, how easy it is to replace the starter while you’re in there, and tips on reinstalling the intake manifold into the engine bay.

How often are you planning on removing intake manifold, to replace S.A.I. 1" aftermarket foam filter?
Did you take the old factory foam filter, out of S.A.I. pump?

We've a $2.00 part in the S.A.I. (secondary air injection) system of the VVT engine, that is taking-out ~$7,000.00 $15,000 $25,000 (inflation) in parts. WOW! I've a very easy and cheap WORK AROUND. You are going to love this ;) This thread is dedicated to the 4.7L 2UZ-fe VVT engine, in the...

Tips:
Begin IM removal, by cleaning top of engine. Pay special attention to the areas, between heads and IM.
Before installing IM. Inspect each intake port for debris/sand, with flashlight. Vacuum out, every spec debris/sand from ports and off valves.
When installing fuel injectors into fuel rail. Lube O-ring, with gasoline.

I had a hard time purging air out of the cooling system after draining the block. I parked the car on Rhino ramps and also turned ON the second row heater under the drive seat. It really helped.
