Hi guys, has anybody thought about making a "Ram Air" to provide more fresh air using the stock box for our cars? i was looking at my engine bay today and see that probably removing the plate located over the radiator and infront of the intake, and fabricating something to route the air from the front grille could work?

I don't believe such a modification would yield anything beneficial for cars used in everyday life. Perhaps a car engaged in racing could gain a tiny bit, but it would likely be more in theory than in any measurable performance gain.

Ironically, those who "hypermile" for the ultimate in fuel economy believe that warm air yields more economy than cooled air. Some of those guys actually try to direct air heated by the exhaust manifold into the intake for a touch of added fuel economy, believe it or not.

Of course, the psychological "cool" factor from a "cold air intake" is certainly a meaningful benefit to a proud owner of a modified car.

I don't know about a RAM air these cars are definitely different from what I'm used to but their doesn't seem to be any real meaningful mods on these cars yet except suspension I have and intake with box (gonna sell as soon as I can post it) I need to tune it because it made the engines strengths and weaknesses magnified. I think a RAM air would be nice but I'd be afraid of water getting in there. I still wonder if the little intake hole is even useful where does the air flow from to get there?

Any who I'm lost maybe try this intake I recommend tuning though with any mods you make to the engine on these cars.

Maybe cut a whole in the liner for a ram air but I'm just guessing I don't know exactly where the intake filter is placed.

Hi all,

Well today i gave it a shot at removing that trim panel that is infront of the inlet of the intake resonator, and voila, this uncovered two vents (the stock one on the left, that has a small grille, and one infront of the inlet) that can provide higher velocity and colder air into the intake, the "hole" that is on the center has a big block of metal to host the hood lock so that one isn't of much help.

After some inspection and cleaning, i went for a test drive and i can say that the throttle feels somewhat more light, it revs a tiny bit faster and doesn't stall that much after being for a while on a traffic light... is like the engine doesn't try as hard to breathe.

Need to test it when rainy weather strikes, but i can see that water getting in is going to be not easely sucked in, first it has to go thru the plastic grilles, then air that bounces of the radiator has to make higher velocity air go thru the hole passing the horn and then into the inlet of the resonator, and even after that, the resonator has a small drain hole, and the stock box has another one too.

I'm attaching some referral pics.

Thanks

Great idea.
I removed this plastic trim several times when I was adding and modifying my horn but never thought of leaving it off. In Principle, the idea is sound. This allows more air to get to the snorkel intake. I will definitely give this a try.
Would like to hear what others think and what results they get; driving, economy etc.

I see that this thread is from last December.

If you really wanted to test, there's a pretty simple method. Use an ELM327 and your phone and take datalogs of manifold air pressure. Then do WOT runs with and without the intake panel to determine if you're getting any benefit (closer to atmospheric pressure=less restriction).

In a car with a wheezing 155hp on the 2.0L Skyactiv AND with intake variable cam phasers, I'm going to guess that this isn't doing much.
