I haven’t taken the time to look to see if the OE plate is intended for a 2UZ-FE, 1FZ-FE, 1HZ, 1HD-T, or 1HD-FTE equipped models, nor how the exhaust/catalytic converters/DPF are routed on these non US market models.
I don’t think the issue is so much heat transfer to the transmission, or...
I’d really like for you to be correct, as this would be a somewhat reasonable “cover” on one of our daily drivers, that really don’t justify a full set of Slee/Dissent skids, and possibly a mild deterrent to catalytic converter theft. My concerns are based on my understanding that a catalytic...
I suspect engine (based on coolant temps), and transmission (based on fluid temps) are going to be substantially lower than exhaust manifolds or catalytic converters, but what do I know…
Shipping wouldn’t really make much difference on a nearly 6000lb vehicle. Neither would final cost on a vehicle that they’re putting night vision on. I’m wondering more about heat + plastic issues.
I’d have to wonder if there is a reason that Toyota didn’t put a plastic skid plate, directly under the catalytic converters, on the US market 100 series.
