How do you get rid of engine bay heat?

Advice needed for my MX5 Mk3(NC) but this question could apply to any force induced petrol engine hence posted here!

HEAT! Lots of heat, not over heating but under the bonnet everything is warm, even the washer fluid. It could be ok or, in my view, the heat could reduce the longevity of various items found under the bonnet, maybe.

I have searched for options and have found that the general consensus is that bonnet vents are a good option to remove heat, (not air scoops, I have air in, I need air exit) I have also found a pressure differential bonnet map to show where on the bonnet the ideal place to put a vent, or pair.

This is where I need a little help. I have found a set of vents from racing beats for the MX5 but the cost is £245 delivered so they are expensive, large and look a little non OE (riveted and BIG)

Have any of you chaps had a good experience with a generic set of vents, easy install and look good, as in no rivet's but which give a good flow of exit air, or am I hoping for too much?

I'm thinking Ford RS, Impreza etc

Thank you !
