I'm toying with the idea of adding the Daystars to my 2017 JK to reduce under hood temps and flutter. I looked at the few old posts I could find on them and they generally have favorable reviews, but one person on Amazon or somewhere gave them bad reviews because of where they allowed water to drain onto (I think on one side he said it was draining on the TCM). Has anyone on here put them in and not liked them? When you see the factory vented hoods, do they have any form of water drain system, or just let rain in on the motor? thanks..

I don't think you're going to notice much difference in hood flutter with or without vents. Take the spring out of the hood and get better latches to deal with that. I do think that ventilation helps with engine bay temps, but I don't notice a difference in the operating temps.....so if you're just trying to keep the bay a little cooler for the plastic and such that's in there....great, but don't expect the engine to run cooler in general.

There are primarily 2 types of people......ones that say don't worry about water getting in....and others that are overly freaked out about it. I'm more of the first and have a PSC hood louver. That said....I'd kinda agree that letting water drain right over TIPM prob not the best thought....even though it should really be fine. I'd prefer to keep water drainage over the main part of the engine/engine cover myself. You should have a little discretion on where you're installing it....but still have to work around the cross supports on the underside of the hood.

This is probably the best 25$ I have spent on my rig so far.

Do the factory vented hoods have any form of built in water drains, or just open?

They just have a wire mesh there....water drains right in, but they are also located a bit closer to the center of the hood than where most put the daystars. The underside support on 10A/hardrock hood is a bit different than the non-vented regular hoods. I've not installed those vents specifically.....so not sure if the cross support will hinder where you can or cannot locate them on the hood.

I can buy that 10A hood as a complete kit (part #82213656AC) from a dealership in NC for $716, but its 250 miles away from me.. Of course my local stealership wants $856 for the same part.. :(

Does that come painted? Round here you can buy the aftermarket hoods that are just like that for $325 or so....but not painted. That's a lot to pay though if you're just after some ventilation. I could never justify that even though they add a bit cooler look. If I was gonna pay for a hood, I'd get either than AEV hood or the TOTL Innovations hood myself. I think in terms of ventilation both of those are much better than the factory hood.

Alas....I just settled for the PSC cheese grater as $130 was more in my budget.

I've been thinking about the Daystar vents also. But when I looked under my hood I noticed that one would be right by the TCM and that concerned me.

Been running them for four years. No complaints. Recommend going to Harbor Freight and buying a skin saw, makes the job super easy.
