Hi all,

On the underside of my side vents on my 1997 uk turbo 2000 I have noticed covers bolted onto the bonnet, which pretty much stops airflow so there's no point in having them surely?

Just wondering, should I remove these covers or are they there to prevent water getting into the engine?

Cheers

Hi Mate, I was gonna take mine off too, but I've just fitted an induction kit so I thought better of it! I know what you mean tho, what's the point of having vents if you can't use them!?!?!?

Can anyone put any light on this?

I beleive they are entirely cosmetic. I seem to remember there being a potential issue it you took the covers off. Can't remember what it was though.

I'd assume that they would help to cool the engine, does anyone know if it poses a risk for sure?

I would think they are for track day use only, I wouldn't want to leave the covers off 24/7. Wouldn't think it would be too good for components to be drenched in rain!?!?!

A lot of people have fitted scoops to the driver side (where the IK is) instead of the slats, i know harvey has removed part of one (he runs an IK as he has a fmic).

Leave them on seems to be the general opinion

The vents are there purely for cosmetic value, hence the underside is covered up. Otherwise every time it rains your engine bay would get water going into it. Not ideal!

Some people with induction kits remove the vent an fit a mini scoop. Stops most of the rain getting in and flows more air to the induction kit. Better off with an induction kit that fits in the wing though with cold air feed.

Now that I can understand, getting ram air on to the induction kit - makes sense!!

Thanks guys, not getting an induction kit so thanks for the info

Doesn't the 22B have vents (albeit bigger) that are uncovered?

I took mine off my classic, back in '97, even cut out some slats, leaving the middle two and put motorsport mesh underneath to lOOk like the 22B ones. Without knowing better.

It didn't cause any problems.

Take em off, I did 3 years ago and have never put them back winter or summer.
Never had any problems in fact when the engine is hot you can really see the heat haze coming out which can only be a good thing.
As somebody has already said, the 22B did not have covers underneath the vents and the layout in those engine bays is identical to the everyday WRX/STi's/UK turbos.
