Has anyone got the o2 sensor gasket for the 4AGZE exhaust manifold?

I didn't get one with my engine so I had to use exhaust paste to stick it on.

Proper gasket would be handy!

Also, do I have to have the supercharger speedometer in order for the knock sensor to flash?

You can get one from Toyota or dare I say it, any exhaust type place, they're bound to have them. Or any motor factor place. I don't think it will be anything special.

I don't know what you mean about the knock sensor flashing?

Does the N/A speedo have the light on if for the knock sensor? Or do I need the SC speedo?

It doesn't flash for the knock sensor? Iirc it's only apexi pfc's that can be set up to flash the cel when it detects knock.

What's the point of the knock sensor if there is no light to show me there is a problem?

The SC speedo has a light that comes on when the supercharger engages, it's done on vacuum I think. Is that what you mean?

There is no light for a knock sensor.

The point of a knock sensor is to retard the ignition if it detects knock and therefore protect the engine. No idea why you'd think there was a light coming on?

My mistake.
