Don’t open that can of worms again. People will argue it’s adding downforce….There is a SIGNIFICANT increase in front end down-force w/the hood vents.
There is NO down-force w/hood vents, there is merely a reduction in lift. And, yes, there IS a difference.
However, I also have a splitter that I modified& 305’s in the front
NOW you have front end down-force!!!
I used 3M double sided rubber edging around the cuts on the hood. Super clean looking. Also sprayed the inside of the hood where it was cut to hide the un painted finish.
Here’s some images. Once all the messy work was done I added an oem stripe, PPF and ceramic back over the top, then black alu rivets to finish the job. Plenty of track events on this setup, with high temps on track in the Texas heat and no issues.
Stationary on a dyno removing the cover will help flow, but on the road it may not (more ram air into the grill to feed the airbox).Here’s some images.

I followed the directions to the letter from the guys at Race Louvers to make sure the vents were cut and placed in the ideal spot for correct airflow.
I’ve got a different setup for the airbox (pic attached). I modified a CF GT350 box cover. But I’ll be probably be removing that going forward because there is plenty of exhaust from the race louver vent directly above the box for any heat, and the fog light cover is removed. We did some testing with both box open vs closed and fog light in/out, and even tried using a baffle for the air flow which was pointless given the massive holes the grill has anyway.
No dyno data, but IAT were lower with this improved air flow. I don’t have figures on that, because I’m lazy and didn’t write anything down.
Yeah haven’t ran it open full day yet. We will see.
Gotcha. Looks good.Here’s some images. Once all the messy work was done I added an oem stripe, PPF and ceramic back over the top, then black alu rivets to finish the job. Plenty of track events on this setup, with high temps on track in the Texas heat and no issues.

Our hood vents are more of a pressure relief exit, not air vent. If the filter is protected from water and heat (High IAT's) then you can remove the hood insulation. Personally, I wouldnt remove it it catches a lot of water from those open vents and directs water to drainage spots.
