I have read a few people have these? What are they?

 

You pull your air filter out of the airbox and get a hole saw and drill a bunch of holes in the bottom of the air box. This will give you better airflow. Some have even drilled a 4" hole in the bottom and installed dryer venting and made a homemade Ram Air setup. Just don't try drilling holes in the top of the airbox!!!!

 

now yu tell me

 

Something I have yet to do... Any particular size holesaw to use with this? Ive got one thats about 2.5" in diameter.. any reason this won't work?

I had originally used a 1 inch hole saw and drilled between the ribs in the bottom of the air box. About 20 holes I believe. It's easy to take the air box out, however if you don't pleasse be careful and don't puncture the a/c line under the box. Just my 2 cents worth.

 

Look at the little squares in the bottom of the box and try to use a hole saw or regular drill bit that fits inside the squares or you may end up with a mess on your hands.

 

Ok.. Ive got a few smaller hole saws as well.. I will definetly take the air box out.. can't see any reason no to.. maybe I will do it this weekend.

Just don't press too hard while drilling or the bottom of the airbox may break! That's what I did on my 98 CTD......

 

Its only plastic, it shouldnt take that much pressure to blow through the box..

For you "cheap skates" (just kidding, I did my box to but have a Scottys 5 now) dont forget to remove the small rubber deflector next to the pass headlamp that connects to the AC condensor. (unless you live in snow country).

 

so when one drills out the air box will one see an improvement in tq, hp, sound, or mpg? i have a 20' magnaflow and need to do something with the intake.

thanks,

a little bit of everything, lower EGTs too

 

I, personally, did not see any of the gains some members claim to have gotten. It made me feel better though.....

 

wierd

with only the swiss cheese mod, i shaved at least a couple seconds on the 1/4mile, I was at like low 12s with 1/2in holes and mid 11s with the 1in holes so then I decided to forget everything and make on GIANT HOLE, now im bordering 10s. SWEET MOD!!!!

 

Um, 10s in the 1/4 mile???
