general rule, OK to mod and wont ruin warranty are

1. wheels change ( do not touch suspension..once you change suspension..warranty is gone)
2. catback
3. adding strut bar

once you change factory setting- even with proof of dyno and reflash map and evidence of suspension work..your warranty is gone

Nonsense. Warranty isn't an "all or nothing" deal. If you change the suspension, the suspension obviously won't be warrantied anymore, but it won't affect your powertrain warranty. And vice versa. Tuning your car won't affect your warranty if you blow a stock shock.

As mentioned earlier in this thread, Toyota wont cover the modified part (obviously) or any part directly affected by the modified part. Everything else is covered.
I have personally had warrantee work done by Toyota on my Hilux complete with suspension lift, bigger tyres (that munched the trailing edge of the front bumper), ECU tuning, etc, etc. They were OK with it and even commented on the modifications so were fully aware.

Would simple mods void a warranty? Things like replacing the plastic chargepipe or the intake?

Yes. They'll say that's the reason it broke. And an intake is not a "simple" mod anymore. It used to be before MAF's and the like. But nowadays intakes are very sensitive to engine performance. For instance on my 2015 STI you had to tune for one. Couldn't just slap it on. At the same time stock intakes are built much better now too. There isn't really any performance gain to be had, and depending on the brand, model etc they can actually lose power.
If you're worried about warranty, don't touch it.

How would they even know you put the car on a dyno . Did you tell them?
