78 comments for such an overlooked tuning mod, that is for anyone doing things properly. You had my subscription at the Will Farrell cut away! Great job lads

I have been looking into this for decades. I'm a believer and will start my next project with these in my turbo truck hood.

Thankyou! I just placed an order for our Maserati project. This company and AeroFlow Dynamics have what we need to stand out!

Wow excellent testing! if it makes this much of a difference on a small miata engine I can only imagine the results are multiplied with bigger vents on a larger engine bay with a bigger and more powerful engine!

Good stuff...thanks for the tech talk as well. 🔥🍻

Really stunning hood vents.

Glad to see this tested. I've been looking into getting a pair. Should probably check out a Flyin Miata oil cooler if you're worried about the oil temps.

Thanks for testing ! 🤘😎

Cool! Pun intended! No seriously that was a very informative video. Thanks for sharing, DC

I started with an angle grinder but ended up using snips on my NB hood. Much easier to get a clean cut with the snips. RTheory vents here and I'm very happy.

Alright this is the second hood vent video I've seen in 2 days and they both seem simple so I think I'll end up doing this while I still wait to find a affordable engine for my miata.

Nice video. Oil temp is no issue unless where you are reading it is noted. I read at the pan on my car and run north of 260. Still looking at vents but you do get more drag so there is a trade off. Thanks to the Miata crowd for always doing great research on these subjects. Very clean install!

this video is very helpful! I'll install a pair of vent louver to my SUBARU "R2-D2" Thank you!

Did this to my 97 over the winter. It didnt need it as the engine is stock, but i think it wanted one…as per the usual, your setup looks much better than what i did. 😃

I believe hood vents provide a bigger benefit at slow speeds. If your hood and engine bay is just a big upside-down cup with a set of red-hot headers inside, it's gonna get hot. Simply letting that air go upwards through natural convection is all you need. Look at the Seibon GTR style hoods for E46 M3's. When they pull the car into the pit, that's where those hoods count.

Great video with really clear install & feedback. Thinking back your previous IAT test for the naca duct and TSI intakes, it would have been interesting to see the individual effect of the TSI's and naca duct. I seem to remember that it was the naca duct that had the biggest effect. Oil temps at 240 on a highway run seems hot. What was your oil pressure like at idle immediately after the run? At 240 F it should have been pretty low (unless you are running 5W-50 oil or similar). Perhaps your gauge/oil temp sensor needs calibrating? On track with my turbo 1.6 during summer temps of 85 to 90 F, I only got a max oil temp of 195-200 F (albeit with an oil cooler). Conclusion: You DEFINITELY need an oil cooler!!

Cool video. Great attention to detail and vivid explanation. New sub.

SNS Mazda cup cozy! That's great lol

Thanks for posting. Got a set of these on the way

Have to admit, I expected more of a temperature drop. More like 10 to 15 degrees difference all around.

Haha I had that same idea for the cx racing sticker

The sticker reaction XD

nice content as usual! The rest of the world would appreciate if you convert the F° to C° :)

ME: Lets use the vinyl applicator. WIFE: The credit card works better. ME: FML

Good to know! Is there a "Black pop rivet" option? ;)

This isn’t just an aesthetic improvement but at the very least there’s a small improvement in heat dissipation?

I have a C6 corvette, I have heavy and light rain in my area and my car sit outside. I drive it daily. How will the vents handle water, can they close? Or do they have shields that stop water leak?

Can I put a hood vent in top of my 2011 Transit Connect.I want to have some air on it.And probably from that hood vent hot air escape up,so engine while in traffic,is cooled. I will put 3 hood vents,two in side,and one big inside liks Mitusbishi Evo.

Look good!!! did you say what the cost is I'd like them for my camaro rs

I think my takeaway from this is that I need an oil cooler.

There may be a solution to not getting water nor snow in your engine bay with hood vents ,but not sure hence I am asking. There is something called rain guards for hood vents but I am not sure if they work nor if they also guard the air away

2 degrees celsius looks like within margin of error though, especially for a 196 avg and ~200 peak temps.

Would that vent fit a 2006 Toyota Tacoma Trd Sport ?

What thermostat are you running in this?

Hi everyone my question is if i do that in my bmw 1 And the engine starts to heat if the rain drops to my engine it well be any damage??? Can someone suggested me if is worth to do it Thanks

Do they fit third generation camaro?

What happens if u get caught in rain. Won't air filter get soaked???

Quick question. You called him Stefon.. Instead of Stefan. How is his name spelt? lol. Cheers!

water and debris is what i worry about when my car sits outside if i get hood vents

Where can I get forna ram 1500 2016? No need to be funtional

On normal riding the test is not sence, you should made this test on a circuit pushing the car and will see a complete different result, please be serious...

Don't call a Mazda Miata a Racecar. Lol, that is the opposite of what comes to mind when someone says racecar.

To make the oil cooler can you run it through to the back of the car into oil filter and then back to the engine.
