Yum! Cold air for the engine never tasted better!

The following was installed on my 1990 Honda Accord 4dr EX Auto It wasn't too hard of an install, but I do recommend
borrowing a dremmel tool if you don't own one to enlarge the stock intake hole in the fender.
Plan on about 2 to 4 hours depending on your experience level. However, I've been told by one of my customer's
that his 2001 Accord 4dr EX, Auto - didn't require any modification of the fender and install time for him was under 1 hour!
So, depending on your year of accord and experience level then it might not take quite as long as my 1990 Accord CAI install ;o)

Stock Air intake 1990 Honda Accord EX 4dr Auto

Here's the entire stock intake after it has been removed. Talk about a boat load of plastic stuff! It's a very good idea to save
all of this somewhere just in case you might need it one day! Mine fit nicely in the AEM CAI box for storage

Once you size up where the AEM CAI will go, you need to enlarge the stock intake hole in the bottom of the fender to about 3" wide by 5" long.
Using a Dremmel Tool greatly speeds up this process! (Depending on your year of Accord this step may not be required and if you are lucky
enough to not have to do this then nice for you ya lucky bum ;o) For around the hole, using rubber tubing and slicing one side or audio wire
tubing will keep the sharp edges from rubbing against your CAI and makes the install look professional. Dang my battery tray is really dirty!
Time to bust out the "Simple Green" and clean it while I have the battery out! 13 year old cars tend to accumulate a lot of dirt

A nice large AEM filter fits just inside the front left fender and has plenty of surface to suck in that nice cold air!
When I say it sucks, that's in a good way ;oP LOL!

The filter comes pre-oiled and will need to be cleaned and re-oiled with a K&N type oil and cleaner kit at regular
maintenance intervals depending on how dusty of a location you live and drive in. If you are worried about water
getting sucked in or live in an area where it rains a lot then you might want to install a water bypass filter such as the one below.
There was just enough room for it just after the bend in the tubing.

The throttle cable worked best when routed above the CAI bypass valve.
Notice that the top of the bypass valve is just below the AEM C.A.R.B. sticker
The valve covers another sticker that basically says install a bypass valve if you anticipate heavy water.
It's a tight fit but works nicely

The AEM instructions for the 90 Accord can be a bit confusing when it comes to the connections.
However, it really only comes down to the encircled #8 metal connection on the throttle body plugged with a rubber plug (supplied),
the metal connection on the air boost valve plugged with a foam plug (supplied) and a rubber tube connected to
the AEM CAI and to the stock engine cam cover hose.

Here is the encircled #8 metal connection on the throttle body plugged with a rubber plug (supplied), and a rubber tube
connected to the AEM CAI and to the stock engine cam cover hose.

Here is the metal connection on the air boost valve plugged with a foam plug (supplied). I used a normal small zip tie to secure
the bottom of the foam plug to ensure it wasn't going to fall off. Also, I had to make a small hole half way into the foam plug
as it didn't have a hole to fit over the metal tubing for some reason.
