Strictly true about the vents, but it won't necessarily decrease under-bonnet temperatures.
Air like water always flows downhill. Downhill in terms of air is from a high pressure area to a low pressure area. The area above the bonnet vent is low pressure and this pulls air out of the engine bay. This is not necessarily good. Air is pulled out of the engine bay, no cold air is pulled in through the same gap, and pulling the air out of the engine bay in this area interrupts the air flow as Nissan designed it in through the front/underside of the car.
Vents (unless designed specially and very precisely), as with raisers, will stifle the airflow efficiency and actually increase under-bonnet temps.

No, no, no. You've completely missed the point.
You need to buy a kit which moves the hinge away from the rest of the car, not the latch. It'll look "well mint, innit, blud". And aid with cabin cooling. Possibly. Panel gaps FTW, yo!
I think you're thinking of the relatively recent to the change in law that states if it's taxed, it must be insured.
If it's SORN, there's no requirement other than it must be kept off public roads.
If you also tell them you're actually 42 and really you have 20 years NCB, it'll be even cheaper still whilst also being no more illegal than your current fraud.
It depends on if the OP means bonnet dampers or adding a couple of washers to the hinge to make it look like the bonnet doesn't fit properly...
Fallen foul of getting distracted mid-reply again, curses!
Don't get me wrong, I realise that would be the extreme and far from the norm, but just as an example. However it's not beyond the realms of possibility, however unlikely.
But if they had reason to suspect a remap had been done, say a post on an internet forum mentioning it for example, I doubt it would be much effort for them to "consult" someone who had the software and could tell...
If you're not aware, and it can't be shown that you might be aware, then it shouldn't invalidate your policy should it not be declared - it's similar to proving intent in a criminal case though, there's not definitive way of proving you were (or weren't) aware.

And so on...
That would incur the wrath of the "have you cancelled any insurance in the last 3/5 years" question though.
Best bet, I would have thought, would be to take out a limited mileage plan for 12 months. That would probably work out cheapest.
Have you HAD any insurance cancelled in the last 3/5 year
Not
Have YOU cancelled any insurance in the last 3/years
It's to check if you've been a very naughty boy and lied then been found out or if you've failed to pay premiums.
Good point.
Please excuse my brain fart moment.
