JWT FX45 Intake Installation

Tools needed:
- 8 & 10mm sockets and/or wrenches and/or ratcheting wrenches
- Extension

I used a whole combination of 8 and 10mm as well as wrenches, ratcheting wrenches, extensions, 3/8" sockets, 1/4" sockets all just to try to make my life easier. Point is that there are 8 and 10mm bolts that you'll need to remove/replace

I've posted a youtube video of my installation for reference. There are two parts to the video for a total of 16 minutes.

Part 1:

Part 2:

It took me 16 minutes with a minor slow-down or two during the video. This installation also removed all unnecessary resonators so it took a little extra time. For the first time, I'm confident that someone could do this in less than 30 minutes. If you JUST wanted to swap the intake for the filter and half of the air cleaner case, the installation could take as little as probably 5-10 minutes.

1. You'll want to remove your fancy power duct cover (#1 in the FSM diagram)

There are two clips that keep the cover (the part that says POWER DUCT on it) on. You can see the two holes in the first picture. Remove those two pins (I just broke them out since I'll never need them again) and remove the cover.

2. Next, remove the MAF sensor plug from the MAF tube

Remove the plug and then you'll need to snip the ziptie holding the wire to the air cleaner case. Be careful not to snip the wire itself. Put the plug and wire to the side somewhere out of the way.

3. Next you'll want to unbolt the MAF tube (#11 in the FSM diagram) from the air cleaner case (#9 in the FSM diagram). There are 4 10mm bolts

You may find it easier to remove the resonator (#12 in the FSM diagram) to make some room to get at the lower bolt in the rear attaching the MAF tube to the air cleaner case. To loosen the hose clamp on this resonator you'll want an 8mm socket. I know there's a phillips head but I've found from previous experience to always use the socket if they provide that option and they do.

(in the picture, the resonator and hose clamp are on the right. Don't mistake that for the hose clamp for the MAF tube which is a flathead screwdriver (and 8mm socket toward the bottom left))

4. Once you've unbolted the MAF tube from the air cleaner case, you can unclip the air cleaner case halves from each other. There are four clips which you can see in this picture. Three of the four are visible. I believe the fourth is under my hand

*** At this point if you want to be lazy and save some time, you can just remove the back half of the air cleaner case (#9 in the FSM diagram) and the air filter itself (#8 in the FSM diagram) and bolt up the intake, install the bracket, replace the MAF sensor plug, and be done with it. But why not remove all of the extra unnecessary resonators while you're at it?

5. After removing the one half of the air cleaner case, you'll have some more room to work. Remove the other half of the air cleaner case (#5 in the FSM diagram). There are two 10mm bolts holding this piece on.
http://gallery.kieranlavin.com/v/car/20 ... 7.JPG.html

After removing the two bolts, you'll need to do some yanking and prying to get it out but don't worry; there are only the two bolts up top

6. Once you've removed the second half of the air cleaner case, you'll see another resonator down below in the bumper that looks like a water bottle of sorts (#7 in the FSM diagram)
http://gallery.kieranlavin.com/v/car/20 ... 0.JPG.html

There are two 10mm bolts holding this piece in. One is evident as you're looking straight down and another is closer up into the bumper and is a bit difficult to see and reach.

7. After you've removed this resonator, you are ready to start putting pieces back together. Bolt the lower part of the intake bracket to the fenderwell. You'll see two holes in the fender well; the lower of which is threaded already

8. Have all bolts and washers ready to go and start bolting up the intake starting with the lower bolt hole back toward the firewall which is where the intake bracket attaches. There are four bolts. Take your time and don't strip or overtighten the bolts.

9. If you decided to remove the resonator (#12 in the FSM diagram) to give yourself some more room, make sure to re-attach it and tighten the hose clamp.

10. Make sure all hose clamps are tight. There is one at the resonator (#12 in the FSM diagram), one at the MAF tube to the flexible intake tube (#11 to the flexible tube on the FSM diagram), and one at the JWT velocity stack to the filter element shown in the picture below

11. Finally, make sure that you reconnect your MAF sensor plug.

12. Enjoy

There are extensive pictures of the whole process and it may help to browse the pictures for various angles that may help you in understanding the installation process:

Re: JWT FX45 Intake Installation

It's WAY easier than the writeup/video suggests.

Re: JWT FX45 Intake Installation

After discussing with a friend, there's a bit of an easier way to get at everything.

You can remove the MAF from the flexible intake hose via the 8mm (I think) hose clamp. Once you loosen this hose clamp up and undo the four clips holding the two parts of the air cleaner case together, you'll be able to remove the MAF with the one half of the air cleaner case completely out of the car. This will make unbolting the MAF from the air cleaner case MUCH easier. This is actually how I did it the first time as well as many subsequent times. However, right before I started doing the video, as you can see in the picture below, my hose clamp started going cockeye and wasn't working properly so I avoided it.

Be very careful in handling the MAF; they are sensitive and are pretty expensive to replace.

The links to all the photos appear to be dead. Can someone please re-post or direct me to good pictures?

Re: JWT FX45 Intake Installation

I have the originals at home. What exactly are you looking for? If I remember, there were probably about two dozen pictures but a lot of it was just crap. Let me know what you're looking for and I can find the pictures for you

edit: shoot me an e-mail if you like and I can e-mail them directly to you. kieran at kieranlavin dot com
