Hi guys,
I don't know if it happen to you guys, buy after bimmerfest I just feel like modding again. So right now I planning on putting Jb4 and DCi as running option. But my car has a vented hood, so I just want to make sure before I do it. Does anyone had experience with DCI under vented hood? Will the water spit on it and will it influence it! If yes, what other option do I have with JB4, I know intake is very important in turns of performance.
Thx in advance
Jason
BTW, this is how the vent located on my hood.

actually intake is not very important in terms of performance on these cars - at least until you start making pretty decent hp numbers.

Not sure if there would be issues with a vented hood. but you could just go the k&n drop in filter route.

I have dci with vented hood for about 5-6 months now without any problems.

I already have JB4 so DCI will be a good next step? what's the difference between DCI and the K&N filter?

Power wise, I don't think much (which is minimal to begin with). Dci sounds way cooler.

Dci and jb4 here. No issues. Intakes will sound alot better you will shed like 30lbs and bring engine temps down by about 10 degrees

so you mean you have vented hood with DCI and no issue at all?
this is how the vent look like on my car. i am just afraid water will spit on the DCI.

You will get water if its over the DCI, its not good it will remove the oils from the filters and the car can take in water if in heavy rain.

if you want the best of both worlds get a MR.5 intake with the vented hood

Yep. Same hood and all for some reason when it rains I dont even seen water residue on the engine. Not sure how it works...it just does

Get the AFE Stage 2 SI Closed Intake Box, Problem solved.

I would not run open filters with an open / ventilated hood. One could argue you would need a good amount of water to cause a problem and they are right. But, why go through all that?

Thx man, but those retail for 300+ right? My budget is limit cause I have to save money for other mods. Any other recommendation?

Have vented hood and ran with dci for about a year. Never had any problems but its pretty dry in this area. I now run stock exhaust cuz I grew tired of the swoosh noise. Plan to eventually run mr5 but for now, I'm back to stock.

Cool, thx.
I am in San Diego which is not raining area. Small rain every now and then.
So I guess it won't be a big problem.

You can go back to your stock airbox, or do a Mr5 DIY intake.

[Indo Rider]

Yeah... No Way I Would Pay 400! Based On What I See Here Sounds Like The K&N Drop In Filter In The Stock Airbox Is A Good Choice For you.

My advice, wait till you have enough money to do it right. You obviously have enough to put towards a new hood?

Could always do a K&N Air Filter on stock box...

Haha, that hood is about a year ago when I got some fund.
Not right now though, guess I will just go with the K&n drop in first and wait till the next one.
Thx man.

Why don't we all think about this logically for a minute. People run scoops and stock intake box through raging down pours with no issues, yes? I know I have, and with zero issues. I've even been directly behind vehicles just throing buckets of water from their tires at my front bumper, and still no issues.

Now, what makes you think the small amount of rain theough a vented hood would be worse?

As for filter oils, buy dry filters. Problem solved.

Yea, I guess you are right , just asking to see if anyone had any issue with it before I make any move and end up regret it.
Thx bro
