People hydro-lock MINs al the time with stock intakes. Usually when the water is about a foot deep and another car comes the other way to create a wave. Now, it is silly to drive a MINI in 12 inches of water, but usually people think it is only a couple of inches and it gets deeper.
AS far as where the air comes from, on MINI's they pretty much found out that with the supercharger, the air heated up so much that the intake temp was not as important as they thought and if you could bget better flows it made a good trade. Now, a big a$$ intercooler helps in this area more than where the air comes from. |

That's a perfectly accurate conclusion for your Civic, perhaps. My ECIS had it's own airbox and was completely sealed against engine heat. :iono:

I had my share of intakes on my civic si, i had an SRI, the heat soak sucked ass. Now i have a CAI intake and thats not to bad. I still prefer my stock air box. better for driving around the city.
I wouldnt imagine that 1 would need a cold air intake. It really depends on where you live. I live in Vancouver were it rains all the time and my filter location driver side bumper) makes it foul really fast. and changing or cleaning that filter is a PITA. Stick with stock, or get a better flowing filter (K&N) if you feel like you need to mod something for that 1 extra pony. |

I can not begin to stress how many dyno comparisons I've seen on stock turbo cars vs their aftermarket intake counterparts, and it seems to come to the following conclusion....
Increases the noise, but unless you have got supporting mods to the point where the intake is actually a restriction (Higly doubt that will be the case for a decent amount of horsepower) all you'll get is more noise, and *MAYBE* a few ms decrease in spool time. (the 135 is fully spooled at what 1500 rpms or something?) Have the supporting mods, or some high HP goals, go for it, otherwise if you dont care about the noise it would seem like a better idea to spend money elsewhere. (also been problems with maf's, tuning and other areas with aftermarket intakes etc) |

I have had 6 intakes on turbos
Having modded an mk 3 supra, 944 turbo and my beloved and now gone STI. I have had many experiences modding and tinkering with intakes....ONLY ONE gave me measured dyno HP. It was on my STI running 25lbs of boost on an fp red turbo and we used a PERRIN Maf (larger housing diameter on the af. meter) and then tuned it according to its flow while measuring on a wideband. This experience taught me that you can get hp from an intake but one must spend money on all supporting mods first.
" You can't swing the chucks with bruce lee until you have first twirled the bo staff with napoleon dynamite !" Mr 2C UR downpipes ; jb 2, cdv and dp fix are all in hand awaiting the car to arrive June 14th- Yeah ! let the modding and the quest for fire begin soon !

That is why paper elements have so many pleats in order to have enough surface area available for air flow as it loads up with debris. |

Isn't there something that can be done with the OEM intake to get a little more turbo sound? I'm not going to do heavy modding... but anything that's cheap or free to improve the sound (like the "golf tee mod") are fair game.

The thing is that often people tend to drive a car like it was a tank. A modded car needs a different style of driving. How many times did I heard people say :the car is leased I dont care or Its under warranty. No wonder they hydrolock their engine driving thru a (lake). Like the guy said above gotta be smart.

If BMW offers its own performance intake, then surely the stock airbox has some room for improvement?

either way, I'll probably consider the BMW performance intake, if it doesn't lose power and makes the engine sound better. |

Unless you are getting aftermarket turbos, the intake is the last thing you should be looking at for power. The stock one is MORE than sufficient. They are a complete waste of money and can mess things up. I had an intake that rubbed against wires and made my ignition cut out. That plus the water factor, and they have been known to cause idle issues on some cars. Just in general they, at best, give you a few hp in real world conditions but the costower ratio is horrible. The risk factor just eliminates it from even being a legitimate option in my mind.
