Oh - Sorry, the way you worded the beginning of your post made it sound like you were asking someone in a thread.

So you are asking if anyone has:

i think he means that little ridge on the radiator cover, by the snorkel

Don't forget that cutting the bump will end up in shorter filter changing/cleaning period and dirtier engine bay. But it really helps...

Ever wondered why the bump on the shroud is there.Its possible that it actually increases air pressure at speeds above 30-40 mph. As air passes over the bump the air pressure increases behind it with a direct pressure increase right at the front opening of the snorkle. Cutting a hole in or removing the bump would nutralize the pressure effect. Also as stated earlier would let in more dirt and a little more hot air at low speed rising off the front of the radiator.

Faster moving air is of lower pressure than slower moving air.

You will go through filters more often! That's for sure. The intent of the bumb is to keep "large debris" out. If anything it just slows or deflects the air from to scoop.

Shave it off?

Just take the cover off - It lets more cooler air into the engine bay - Ours has been off since summer of 2000.

[britfolk]

is it ok to do all three mods?

 

[Cem Aygun]

Bump is there to create turbulance and reduce dust and particles going in. If you cut it open, you get real cool air going in, especially at high speeds.

But that causes 2 things:

1)Your intake sound increases (depending on your filter, it can multiply as the front plastic panel starts to act like a drum with air flowing through it).

2) You get more dirt in.

The second problem can be easily solved with more frequent cleaning. The first problem can only be solved by removing the plastic cover. That may help your performance but you will end up with an unbeliavably dirty engine bay in no time (if it rains where you live)

I agree that the "bump" is there to deflect large debris. It does a good job of that. But, I did some drive tests with my OBD II scanner. The difference between the Intake Temperature and Air Flow readings with the shield on and off was so small (barely readable) that I put mine back on.

By the way, I have the SVT snorkel. I don't know if that makes a difference in the test. It does make a measurable difference in air flow.

Just my .02
