Feel free to add something, if I'm missing a major point--
It's when the heat from the engine builds up, increasing the ambient temperature of the engine bay.
That means the air (which is ideally cold) being pulled in by the intake/induction is already hot.
This impacts a couple of things.
Old school rule of thumb says +10f increase in ambient above air temp institutes a loss of 1bhp (old thinking, it's a lot less linear than it used to be, in actuality).
The basis of the loss is to do with:
- the air/fuel ratios calibrated by the ECU (hotter air has less oxygen per unit of volume due to thinness),
- the viscosity of the oil under high temp
- the dissipation of the heat into the cooling systems, blah blah nitty grittys
TL;DR basically it creates inefficiency. All of these things cause a knock-on effect creating timing issues.
It's a real issue with big blocks, iron blocks and Vtech. Not much of an issue with >3l engines (with the exception of vtech). Sitting in traffic will be the main cause of it in our uses.

Driver's frown included for free.
Thanks, it was a lot easier than i expected.
i gotta say, they actually do work. Since installing them, i have not had much (if any) water / dirt splash on my doors and rear.

Take the good and leave the bad

Installed Deautokey tail light and reverse LEDs. The reverse bulbs are really bright and really happy with those. Not sure how I feel about the tail light bulbs though. When the headlights are on and the bulbs are on (dimmed), when I touch the brake pedal (bright) there isn't a huge difference between the dim and bright modes. So other than the 3rd brake light you might not know I was hitting the brakes. Anyone else experiencing the same scenario?
Left only replaced:

Ps. Please disregard my poorly lit license plate on the left side. I ordered a different style aftermarket backup camera, as the one I have replaces the license plate light and is garbage. I will be ordering the Deautokey license plate LEDs when it arrives.

I put a set on my R last week.. Wil probably put a set on the 1.8 as well. I'm quite impressed with them!

Finally got around to installing my euro switch and automatic light sensor.

Finally? Those take literally 10 seconds to install.
