I mentioned in my last blog update about my musings regarding engine cooling via some movement of fresh air. Since then, I've cut the 5 holes just above the throttle bodies and added some mesh. With the engine run up to temperature, you can really feel the warm air rising from this area, so it can only be a good thing with regards to inlet temperature.
For a laugh a I drilled them out and finished the edge off with a grommet. Yes, I know they won't do much in the way of cooling, but I think it looks rather good (better than a wasted recess anyway).
