Should I be able to see through the side vents

Recommended Posts


Just got my car back last week from a dealer oil change (04 S). I happen to be washing the car, and I peered into the side vents - the driver side has a screen behind it. The passenger side, however, does not have one, and I think I can see clear through to the engine. Is this correct? I somehow doubt it, since the opening looks the same as the driver side. If it should have it, the next question is there any reason this would be removed during a yearly service, which was basically an oil change and a brake fluid flush (car has 10k). I just wanted to know whether I should blame the dealer for this.

It is normal, the left is the engine air intake to the air filter with the water screen, the right is open to vent the engine room, you can see the fan.

Thanks for the info! Very helpful.

That is the way it is on a 2003-2004. The screen is to keep cigarette butts out of the intake. The other vent is for the engine compartment cooling fan and it does not have a screen.

I don't even think you can replace the entire grill. As I understand it, the air vents were moved and reshaped for the facelift in 2003. It seems to me, though, that putting a screen behind the earlier intake wouldn't be too hard. It looks to me like the earlier intake strakes were thicker, though, and since they're black instead of color-coded, a screen would probably be harder to see than on the later cars.

I think the earlier cars (but not the earliest ones) had an intake snorkel to deal with the whole a-flaming-cigarette-lights-the-air-filter-on-fire issue, and also to avoid sucking water into the engine.

On a related note, I've had my car for five weeks, about two of them drivable, and I gotta say, those vents appear to be a lot more important and functional than they were on, say, my old MR-2. Judging by the amount of rainwater grime and road filth they collect, they seem to be pulling in a lot of air.

On the MR-2 I don't think the intake was actually sealed to the left side, and the right side was just a screen with no fan behind it, so that probably explains it all.

I love my car.
