I don't know what these gaskets names are. I can't seem to find them? If you know the name i can use to find them, website, or part number that would be great.

 

Toyota can get those 2 gaskets. But why are you replacing the 1 behind TB?? Is it cracked/ripped? Part # 22271-46070

I've always told Toyota that other gasket is the top of the intake manifold gasket aka Y pipe gasket. Part #17849-46020

 

Im doing plugs, wires, and valve cover gaskets. So while i have the throttle body and y pipe off i figure i might as well replace those gaskets. I'd rather have them on hand anyways even if i wasn't planning on changing them in case they ripped while doing this job.

I had got the part numbers already thank you. parts.com had the gaskets muchhh cheaper then dealership. and still genuine oem parts.

 

I understand the y pipe which meets the plenum gasket. But that solid gasket behind the TB I've never had to replace as it's a pretty strong gasket unless you're wrenching down pretty hard on it.

 

if your doing plugs wires and gaskets you dont need to disassemble those parts. just remove all lines from intake and move it out of the way I almost did the same thing until i realized I didnt have to lol food for thought just saying
