Default Hood Scoop Cover

Hey i have a 98 legacy gt and for some reason there is a cover on my hood scoop. would it damage the car anyway if i removed the cover giving the engine more cooling?

US-made Legacies come with the hood scoop insert as standard. It's there because every other country came with a turbo-charged version of the engine. The hood scoop would be where the intercooler would be.

If you remove the hood scoop insert, you run the risk of too much water being forced into the engine bay.

Which really isn't a risk at all

You may want to freshen some electrical wires with di-electric grease in case a rainstorm really floods the engine, but I doubt you'll really run into any problems. The intake won't be effected by this, and that's where you really want to be concerned about water flooding.

Well, how much water would actually come through? It's not that big of an opening.

Not enough water to worry (if you keep your engine properly maintained). I use cleaners and sealers on the engine connections as part of my routine maintenance. There are special sprays you can buy specifically made for cleaning and weather-proofing electrical connections... Your only problem may be that it supposedly rains a ton in seattle, and the more water that gets in, the better chance it has of working its way into elect connects...

Why do you think removing that block-off plate would give the engine more cooling, and why do you think the engine needs more cooling?

I have been running without that hood scoop insert now for 4 years. No water problems. When I detail my engine I spray it right down also.

Yeah, and I should've mentioned earlier that I spray on a can or two of engine degreaser once a year, then hose it off. But, like I said above, I always use the proper greases and sprays on my connections to keep them sealed from moisture. A bit of water won't hurt your engine at all...

hehe, it does.. i ran my outback without that plate for almost 2 years.. after an autocross or rallycross you could see all the heat waves just flowing up and out of that scoop.

So your coolant and oil temperatures were different?

How about when you're actually driving and you're forcing air into the engine compartment behind the radiator, thereby reducing the differential pressure across the radiator and reducing airflow? Was it running cooler then?

after i blew my HG my temp guage never really moved when i had the cover plate of or off. i mostly just used it for venting. but if you look at the SS's they have a scoop, but no intercooler just a chimney but that doesnt seal with the scoop either. like i said i did mine just to help with venting after i race. i also noticed that when i was driving in the snow up to the mountains it stayed cooler than it used to, i could also see the heat rising out of the engine bay all the way up timberline road.

Heck, I'd remove it just for that effect.

there are screws found around the plate, you can just bend the black cover a little bit and see it easily, i think there are about 6 screws and after those are out the plate is good to be taken off.

There are 6 metal screws and a plastic screw that I had to tear off because it was stripped out. But it was rather simple (and I am amazed). I've wanted to do this for so long, but I thought I had to cut stuff.

Just as a tip, it's easier to puncture the heat shield than try and bending it back. It tears really easily and bending it did more noticeable damage than pushing the screw driver straight through it.
