Where can I found a cold air intake for a 2001 Honda passport?

A) It's "Where can I FIND" (present tense), not "Where can I found". FAIL

b) Do an internet keyword search. Here: https://www.google.com/...c3_N4wC_jM

c) It's a complete waste of money. It will not enhance the performance noticeably.

On the frozen food aisle with the grocery store.

Don't bother. The power gain, if any, will not be noticeable on your 17 year old jalopy.

Under the hood. The stock intake is the best engineering you'll get. Aftermarket CAI is junk and a fantasy and a waste of money.

Under the hood is a factory tuned one. Your vehicle is tuned to work with it.

Do you have an engine/ecu programmer and dyno with an experienced technician to get your engine tuned to work with your new fancy piece of plastic. Are you willing to dump $1,000+ to get your vehicle to work properly with it?

All motors come with a perfectly fine cold air intake from the factory. It's just plastic instead of chrome and has a easy to replace throw away air filter.
The after market CAI that have a K&N style cleanable filter can ruin MAF sensors. The oil on the filter migrates to the MAF and causes failure.

My answer generally reflects all of the good answer here. However, understand that the Passport isn't a Honda, except for the badges. It is an Isuzu Rodeo. At the time, they were introduced, Honda didn't have the resources to build an SUV. So, they turned to Isuzu for help. The Acura SLX is another example. It is the Isuzu Trooper. Aftermarket parts won't likely be specific to the Passport since Isuzu pulled out of the US market in 2006.
