Engine cover.

[1FstYota]

So took the engine cover off couple times and each time it gets me in how heavy and insulated it is.

From a performance point of view heat is the enemy, but from an engineering point of view if it was designed that way it must do something.

Since this section is pretty dead anyone wanna get in on this and why it was designed this way? I drove it without it no substantial heat decrease or noise output difference.

So it intrigues me on why it has to be the way it is.

I think it is just for looks. Needs to be heavy duty to withstand the engine heat.

I suspect it reduces sound level in the cabin, also.

Also, 3.8L at least has a resonator built in. I leave the cover off because engine sounds raspy enough as it is.

Anybody painted their engine cover tastefully? I'd like to see pics of that.

No, but I think some people have asked about the KDM version with the wings logo. Not cheap, since I think the OEM part is over $400.

What is a resonator? What model year?

Interesting, the cover doesnt have a resonater, but it does have some super dense foam.

I have a suspension that its some sort of flame retardant due to the high pressure nature of GDI.

This is the resonator "in back of the power steering reservoir" under the cover on a 2011 3.8.
It’s proposed is to silence the drone of the intake air flow.

The 2012 has two resonator "bottles" attached to the intake pipe right before the throttle body. I assume they accomplish the same goal.

The term is Helmholtz resonator, and yes, it does cancel the intake droning everyone is likely to get at one RPM or another by going to a CAI without one or more.

2009 3.8L. Black plastic box on underside of cover on driver's side behind hole for oil filler. It has two ports, one facing firewall, the other facing left side of car.

OK, but that is separate from the cover itself, right?

I believe it was said that the engine without the cover is like seeing Darth Vader without his helmet.

As for it's purpose: It's just a way of getting us used to seeing engines like this so when they seal the engines in a few few years, we won't be 'surprised' all that much when we cannot take the covers off. The engine will be sealed for the life of the car...(gov't conspiracy), preventing shade tree mechanics from accessing anything more than the dipstick and oil fill tube.

In my case, I have to take the cover off for each oil change, since the oil filter is on top of the engine under the cover. GDI engines have oil filter on bottom of engine.

Which makes changing the oil in the GDI a bit of a hassle. I don't mind going under the vehicle, but it is a bit annoying having to unbolt all of the protective plastic sheeting just to get to the filter.

On my previous Hyundai vehicles the skid pads were still there, but the engineers/designers had neat little cutouts that would allow access with hand tools to the filter without removing anything else. I think with the Genesis Hyundai just carried forward the 2009-11 pads without any design changes.

Minor grievance.

It's a plastic box that is attached to the underside of the cover. The mounting holes that attach it to the engine on that side are on the bottom of the resonator.

OK, I pulled the cover and see it now. I didn't even notice it the first time I looked. I guess that explains why the 2009 V6 cover costs $434 online ($534 MSRP).

The V8 cover for 2009 only costs $265 online ($331 MSRP), so I guess it lacks a resonator?

The cover for the 2013 V6 GDI is $274 online ($343 MSRP). 2013 5.0 cover is same price as 2009 V8 cover.
