Installed the 1zz throttle body -

[yarstar]

I have a AEM CAI which I had to stretch some to get to fit, but it did fit. I looked at the OEM sitting in my garage before I tried to install the new TB, and saw it might be a significant problem to make work. Maybe getting a slightly larger diameter piece of rubber hosing (the AEM looks like radiator hose) and use that.

Please keep us updated on this TK. I am very interested in whether the dealer can re-calibrate the ECU to keep the CEL from coming on.

Thanks for today's update too.

How did you manage to stretch it? I really don't want to start looking for a replacement hose, especially since it may end up being too large for my existing intake.

The AEM hose is more pliant than the OEM hose. I heated it in hot water and then worked it on the TB first, then installed the CAI. It was so tight I didn't use a hose clamp. I think you may have to go with the aftermarket, or another OEM hose (Corolla, maybe?).

I just measured the inside diameter of my 1ZZE TB = 60mm. The inside diameter of the OEM hose is 54mm. That's not gonna stretch that far. The hose has to stretch to the outside diameter of the TB, which is approximately 64mm. The rubber is alot thicker on the OEM hose than on the AEM CAI hose. I'd be very impressed if the dealer gets it on. I bet they'll have to use something else. Sorry your having problems.

Thanks! I guess I'll have to do that then... I just don't want any fitting issues at the other side of the hose. Hopefully the bracket can get it tight enough to prevent leaks.

BTW, I've asked the rep to check about the ECU compensation thingie. I'll let you know what he tells me for sure.
