i have an 07 4.0.... i was going to do the mod earlier, but i cannot get that dang air box out! i sprayed some lube on the rubber grommets and tried to pull it out of the side first and then pull it up... i even stuck a pry bar on the damn side grommet and would not budge... and i was using a 15" pry bar... any tricks? even if i were to put an aftermarket intake on, id still have to get that box out but WTF this thing is TIGHT in there

 

mmm i never removed my box my skinny hands did the trick lol

how long did you wait or at least try to spray some more and try again

 

try putting a little screw driver down in the grommets to pry it up

 

i didnt remove my airbox either...you should be able to just tilt the box and slide it out...mine was done in like five minutes

 

That's what I was going to recommend.

I had a hell of a time getting my air box out this weekend - I put a long flat head screwdriver in the space between the grommets. That braced it against the panel underneath the box, then it came out sweet as sugar. Mine was dirty as hell though. Took about 30 minutes total to get the box out, it was not a happy camper.

 

I worked mine forever and finally I just got pissed and pulled it out with my hands....

 

yank that sucker out... thats what ive done every time ive pulled it out.

 

man mmy airbox came off easy on my 07... but I put the silencer back in, lol. I'm gonna leave it alone

 

mine was breeze to take out.

 

your truck likes the silencer in there, lol...

 

I used also slid a screwdriver under the box near the grommets, and pulled upward. It took a little force, but it came out. :)

 

Mine has been a royal pain in the rear and I haven't been able to get mine out. I'll have to try ya'lls little tricks.

 

Why? (I've never done this mod so honest question)

 

what i did to get my air box off on my 3.0 is i jus pulled and tugged on that thing like crazy, then i finally got pissed off enough and jus pulled up on it real hard. be carefuly though because i cut my knuckles up pretty friggen good.

good luck.

well i think im going to give it another try tomorrow after i mow the yard at my parents house.
and then ill be able to tell any MPG increase or decrease since i drive alot of highway miles 95% of the time...

 

i couldnt get mine out. someone at near me just pulled and it popped out haha

 

I gave up trying to get it out. I was able to just remove the rubber piece and the silencer.

After I pulled off the intake ducting to the throttlebody and after seeing how small it was I didn't feel it was necessary to cut up the box. The blade is more of a restriction.

I did notice a little bit more power on tap.

 

I feel your pain about that stupid airbox. I actually broke one of my gromit plug thingys a long *** time ago when i did my airbox mod... tho that was before i was smart enough to use the wd-40 and such.

As for the moddding itself: I dont much see the point to hacking the hell out of your airbox vs just removing the silencer.... All its going to do is allow more crap to get up and in there (especially when ur in the dirt, water, etc) and with the size of the intake tube your not going to get any better airflow =/

 

I hacked mine up when i did it.. though I wanted all the intake sound i could get! haha
