Hey guys been looking at mugen airboxes and ice boxes thought i could try making one, so i googled it and found some DIY's on it too so i gave it a go and this is how it turned out


Materials:
x1 - Can of black paint
x1 - 4" PVC pipe
x1 - 4" Flexible pipe connector
x1 - 4" Range hood damper
x2 - 4" Elbows
x1 - OEM air box
x1 - Packet of blind rivets

I got most of these items from bunnings, oem air box are useful so don't throw it out and the range hood damper i got it from a range hood i was installing they had an extra damper and asked if i could take it and i was pretty happy it was 4" as well ;););)

Tools:
- Ratchet set
- Flat head
- Drill
- 4 or 2mm drill piece
- Silicon or Super glue

Step 1: I Sprayed the elbows first black. ONLY 1 of them spray the inside too so it doesn't stand out :)

Step 2: Once the elbows have dried up i measured how much i had to cut from the 4" pvc pipe to connect the 2 elbows together i did a rough estimate so it's not 100% accurate but it'll fit. You will need to cut out 3 pieces for this. 1 just a little longer for the range hood damper.

Step 3: Connect the longer pvc piece to the range hood damper and glue together i used both silicon and super glue just for extra hold.

Step 4: Connect the flexible pipe connector to the bottom of the air box, some adjustments have to be done depending on the thickness of the flexible pipe i got a pretty thick one so i had to shave the side a bit, i tried taking a photo of it but it's hard to see what i did to it. once it's connected to the air box tighten only the part that connects to the air box for now, check if the range hood damper flaps are opening and closing in the right direction and that it open and closes freely.

Step 5: On the side of the range hood damper and flexible pipe connector drill a hole and just make sure that the holes for the range hood damper and flexible pipe is lined up. once the holes are lined up put in the rivet blinds to hold the flaps down to prevent them from opening and to help prevent your car hydrolocking

Step 6: Assemble the whole thing together and should look like this.

i used black tape to prevent the pipes from moving around or falling off, i dont wanna glue it together just in case i wanna take it off or do something different it's up to you if you wanna glue everything together.

ok once you've tightened everything your done! =D go have a test run! i noticed there was alot more top end power ;)

If you rivet the flaps down from opening, how does air get in? Am I missing something

well air does come in still depending on how high or low you drilled up onto the damper i drilled 5 holes for different levels the flaps would open like i said it'll close but small amount of air will come in1718517186

yeah car feels like it's breathing alot better, i've been running an sri and adding this to it feels alot better alot of top end power :)

Nice DIY, but I'm also curious as to whether or not the range hood damper would be restrictive to the air flow? I'm sure some air would get it, but would it be more beneficial (power-wise) not to have this component? Though of course it would make the intake more vulnerable to hydrolock...

I actually wanted to do this on my EG sedan intake with a pod filter in the OEM box and some flexi-pipe running to the bumper, but I couldn't get a pod filter to sit inside the box lol

thanks bud! umm only reason why i've put in a range hood dampers is because i'll be doing a jdm front soonish and the jdm front comes with j's racing duct so the pipe would be exposed to more air flow and on rainy days, water and there's no way of covering the j's racing duct. so i added the range hood damper, i'd only put in a range hood damper only if your bumper been damaged and water could get inside and the splash guard is damaged too (i think that's what it's called) apart from that if everything is tight no need range hood damper. also yeah i had the same problem trying to fit in the other pod filters i had had a fujita and specture none of them fitted without altering the air box so i just got a K&N one fit perfect :)
