Opening up hood vents to vent heat

[Milkbone K9]

Has anybody opened the hood vents to exhaust heat? I went to check oil on my 2025 Raptor and gotta a nasty surprise. I thought hood struts were a waste until I grabbed the prop rod. I have seen replacement hoods but $$$$$$. In my early days I would grabbed a Dremel. Suggestions??

They actually are open and functional from factory:

I'd love to put these on my XLT.... but I think the hood is actually different from the Raptor

I have not but I've put some thought into doing it as well. I think maybe first step to helping them work as they currently are would be to cut the underhood liner in positions under the vents. This would hopefully allow much more heat flow through the vents as is. And I know many people just remove the whole liner (at least on other vehicles, maybe not necessarily on the rangers yet) but I would suggest against that. As you found from the temp of the hood prop rod, I don't think you want all that heat directly up against the underside of the painted hood. After that, maybe look at the structure of the vent and see if they can be strategically opened up to flow even more than they currently do. Just my $.02

I would assume the underside of the vents is constructed in such a way that water can't drain down into the engine compartment? (I haven't looked...)

The extractors are down and rearward facing, and they open up to a low section in the hood meant to channel water to the passenger side where the tray, bolted to the cowl, is located. You'll see that the rubber plug on the driver's side (above the brake reservoir) is missing on the passenger side above the tray. That's where the water drains from the hood to the ground.

I didn't cut any plastic yet, but I plan to do a little strategic cutting on the extractors like @DirtDerrick did, as well as some trimming of the hood liner. I've already found one hole clogged with debris, and then another two covered completely with the foam liner instead of open to the channel below.

I believe the heat mainly escapes via the water drain hole and through the body clips on the corners that hold the extractor in place. Not a ton of improvements to be made without additional cutting, but every little bit can help.

Below is my DS extractor right after removal. I think everyone should pull theirs to at least make sure the slots are all uncovered. Mine weren't, as you can see by the little holes where my blade pushed though.

That same foam piece on mine covered the entire piece. And it was like they pushed down over the screws and it tore around them. The hood liner and then that piece, i guess some heat gets out enough to call it an extractor. Kinda like grass growing through concrete, it finds a way.

Here is the rest of the job. I cut a small section, roughly 2x6", from the hood liner for better draw out of the engine bay. You can sort of see where I hacked off the lower lip of the extractor housing and the additional light that now comes through the openings.
