i just bought a 2000 Civic Si and i am putting in a cold air intake. I have heard from many sources that Mugen makes an intake that Honda approves like a factory intake. Is this true??? Is Mugen the best intake for my Si or would i be better off with AEM or Injen????? Thanks

 

first off welcome to ht...i know there are lots of people in the philly area. second...think about a cold air before you get one...there is a lot of pooling around this area when it rains and i know of two people who have hydrolocked their motors from having a CAI...just my $.02.

 

yo whats up thanks for the welcome.... doesnt a bypass valve solve that problem arent they made to keep water out???? i thought about the water problem but i also thought a bypass valve would save me. let me know. thanks

Ive been in my friends hatch w/ CAI and the bypass valve. When he did hit a puddle of water, his engine bogged out almost to the point of stuling. It did not hydrolock his engine, and it does work, but yet i have heard of stories withthe bypass valve and they have hydrolocked their engine. I guess it really depends on how much water/deep the puddle really is.

My .02 would be to get a short ram intake. No problems at all. Not even taking a risk

 

Just get a short ram. The difference is minimal and hardly noticeable. I have had an AEM CAI for three years with no problems, and I don't even have a bypass valve. I just left all of the splash guards in place and it has been fine.

 

Mugen does make an intake for your car but it is for competition use only:

Comptech makes a product called the Ice Box, which is similar in design to the Mugen and is CARB approved. Like the Mugen, it is a short ram intake with a box covering the filter and a tube going down to the bumper. This way, you get the benefits of both the short ram and cold air intakes and Comptech claims that it won't suck up water:

The AEM and other traditional cold air intake systems have their filter placed near the bumper, so it can suck up water more easily. The bypass valve is probably good insurance, but I would still be careful. Also, the bypass valve would reduce horsepower by a little.

 

i've been told that if you are using a bypass on a CAI you might as well just use a shortram...same difference. i went from a shortram to a stock airbox w/ k&n drop in and felt no difference what so ever. search around i am sure there are dyno plots of the differences between all of these scenarios.

actually, you are incorrect here. A cold air intake does take advantage of the SLIGHTLY cooler air by going down in front of the fender, however that is NOT why it makes the difference in power. The temperatures are not that significantly different. It uses a longer pipe, which actually accelerates the air as it travels through which helps to get more air, and higher velocity air into the chambers which keeps the gas atomized better for a better burn. Of course that is merely the THEORY behind it. Dynos on different cars show much different numbers with different intakes. Your best bet is to pick the one you are most comfortable with.
