Engine Cover On or Off?

I have noticed a lot of people keep their engine cover off. Is this better for cooling/heat dispersion?

I think most take it off to 'be different' or because they have a different intercooler or turbo set up.

 

 

In my opinion the boxer engine itself is not a very pretty engine in the first place. I understand why Subaru chose to try and cover up the engine on the LGT as they wanted the bay to look more 'upscale'.

Some think it's an important part of the airflow dynamics, others realize it won't make a huge difference either way.

 

I believe it will allow for a slightly higher air pressure over the intercooler but I don't believe it will make much difference.

Should also help keep gremlins off your electronics and tidlybits. I would keep it personally.

Good input. Keep it going!

I kinda like the engine cover, so I've opted to keep it on.

Keep it on. It looks nice when you polish it all up!

I like how it looks, I even cut it to fit my BOV, I think like Gire said most people take em off when they get into aftermarket intercoolers/turbos

if u dont have any aftermarket set up that requires to remove the cover, just keep it on. I even bought the JDM engine cover to make my engine look neat + cleaning is a breeze ..

 

KEEP IT ON!!!

Alright, I think i'll keep it on!

 

Well, it's off right now since I just installed my CNT/ERZ downpipe today, and still need to trim and install the heatshield :-)

All my pop-its holding the cover on broke, and I didn't much care for it flapping around in the engine bay, so now it is decorating the wall of my garage.

my count:

-1 missing completely

-1 very broken and can't even really hold itself in the hole, much less the cover on the engine

-2 partially/mostly broken.

 

I hate those effing clips.

Keeping it on will cause a nice seal between the intercooler and the hood scoop, resulting in direct channeling of the air flow on to the TMIC.

 

But I'm sure everyone knew that already.

I need more of those pop it's

 

both my engine cover and my intake duct is unsecured

I'd be scared to ask Subaru what they charge for replacements.

 

Your local auto zone should sell bags of various sized pop-its and grommets for cheap.

 

Hell, I just saw a bag for sale the other day from my local Canadian Tire. If we have it for sale, lord knows the USA can get something like it.

Took my cover off 6 years ago when I took it off the first time and lost one of the poppit crap things. It's been off ever since, 129,500 miles now.

Mine is off because I'm short two pop its. I haven't done any datalogging to back it up, but I don't think it makes much difference at all.

in case u need more "pop it"

 

I have 20 in stock

You can buy a whole bag of ones that look just like the stockers for a few bucks at AutoZone.

 

Mine is going back on once I modify it a bit. I'm cutting off the TMIC section of it and may have to trim some for the intake but it should go back on in some fashion.

You honestly don't even need pop-its or anything else to secure the engine cover. Just line it up right and close the hood, it's not going anywhere once the hood is down.

I think the issue here is rattling, though.

Mine is off, only because the previous owner didn't trade it in with the car. If I had the choice, then I would keep it on there.

Mine is on but it is trimmed to fit the AVO intercooler and the extra hoses for the air/oil separator. To make a tight seal around the intercooler, I used JB weld to glue on open cell foam rubber insulation. Then I had to glue a strip of aluminum (painted black to match) to the top back part so the baffle would connect with it and not touch the intercooler directly. Otherwise the baffle would block off the last 2 rows of the intercooler.

Left mine on because someone much smarter than me put it on there with purpose.

Took mine off because usually smart people dont know what fast is! (I just totally made that up so dont get offended)
