DIY: how to remove hydrocarbon filters from 2024 Mustang GT / Dark Horse

CA emissions aren't that hard to get around. They have private testing shops.

Removed mine a week ago, really easy, just loosened the intake tube,removed the end vane,carefully unscrewed and pulled the sensors still plugged in out of the way, left the molded triangle pieces in place and used needle nose pliers to unwind the carbon and plastic windings ,reinstalled end vane put back together.. no need to pull the whole tube assembly off…

I think i like that option better.

I did same but I just took off whole tube, it is just easier and more comfortable for me to do so, anyway it is just one more screw that holds it on a throttle body

Could you snake them back in if you had to?

It’s possible but would take some patience…

Has anyone encountered a check engine light after this? I did this two days ago, drove it about 80 miles and today, got a check engine light. I'm charging up my PC to hook up FORSCAN and try to read codes. I'm a MAC guy, so this is the only reason I still have a PC. It's amazing how many updates you need when you haven't powered up in 18 months...

Don't want to be a wet blanket but to get 12+ Hp from removing these light duty restrictions would amaze me. We built a lot of engines in my day and to get 30-40 WHP requires IMO a lot more to be done. Wouldn't it be nice - but that's sure not been my experience. Again, with respect, any driver who can "feel" the difference in throttle response with the kind of "modification" discussed above should IMO quit their day job and race NASCAR. Just sayin' ..... BTW attached from back in the day. One of our garage specials - a 350 stroked to 383 with 400 "twitchy" HP tuned down to a nice loping 390HP...... just for fun.

Thank you so much for this!!!!!

What you will need:

• - 7mm socket
• - 8mm socket
• - 10mm socket
• - T20 bit
• - Body clip removal tool
• - Something that can cut in small areas (like wire stripper-cutters)

Directions:

1. Pop off the air filter cover. this is done with 2 small clips in the front of the cover. they are very easy to remove and replace.

2. Take out the black 10mm bolt holding the intake tube to the air box. it really only has resistance for a small distance, then can be undone by hand

3. Loosen the clamp on the air filter. it has an 8mm bolt to loosen it, then take the filter off completely

4. Loosen the clamp holding the intake tube onto the throttle body. it has a 7mm bolt to loosen it

5. Disconnect the crankcase hose. Driver side has a blue clip that you reach under, pull it towards the front of the vehicle, and pull the hose off. Passenger side has a black push button that you push in and pull the hose off

6. Unplug the mass airflow sensor and pop off the anchor holding the wire to the intake tube with a body clip removal tool. remove the intake tube from the throttle body, then unscrew the two T20 screws and pull out the mass airflow sensor. you will bend the "fins" on the anchor, there is nothing you can do about it and it will work fine after re-installation

7. At the end of the tube where the filter attaches, there should be a sort of plastic grate that makes an "H" shape. This is an insert and on either side of the insert there are little clips. pull them inwards at the same time and pull the insert out

8. Further in the tube is a 3-spoke structure holding the hydrocarbon filter in place. use the cutting tool of your choice to cut each of those spokes as close as you are comfortable with to the base on the outside of the tube

9. Put your hand in the small end of the tube and push the filter out. then repeat what you did for step 8 on the second 3-spoke structure

10. Re-install the tube, doing steps 1-6 in reverse. NOTE: the mass airflow sensor has a small arrow on it. that arrow is to be pointing the direction of air travel towards the throttle body. Repeat all steps for the other side
