Custom Intake Ducting-Front Bumper to Filter

[Dyesuperman]

Home Depot is at it again My intake temps were extremely high during the summer so I fabbed up some intake ducting to help out for the upcoming summer. I have yet to seal off the filter to the ducting as I am trying to decide the cleanest way to do so, but this should help as is nonetheless.

I know this has been covered numerous times, but people rarely post pictures of the individual parts they used and such, so this should help others that want to make ducting without cutting holes or any type of modifications like that. If you have a front mount and short route piping, this is your solution for easy ducting. Here goes

First of all, I had to compare prices. Lowes and Home Depot were very close in pricing so I just went to the one that was most convenient at the time, in this case Lowes. The pictures are from Home Depot but they are the same parts.

I bought:
6" 90' Adjustable Ducting

6" to 4" Reducer Ducting

4" 90' Adjustable Ducting (I know it says 3" but it looks exactly like this)

And the last piece I didn't get a picture of at the store because I found it last minute but it is just a 4" piece that has slots already cut in one end to folder over in a non-circular hole. Here is a link to the exact same thing except for the link shows a 6" piece, I used a 4" piece.

Gofer provided a list as well, so here are the links to every piece that is needed.

The lowes link is similar to the used piece here. You want the 4" version of it, not the 6".



So began the fabbing up.
I attached the starting collar piece to the factory smic piping hole. I had to kind of work with it to get the tabs up far enough but it will work with some force and coercing. Once you have it up far enough just grab some pliers or something and start bending the tabs over like such.

At this point you should have this

So now you want to take off two of the slidable adjusting pieces on the 6" ducting. No pictures of this but you can just bend the piece in and it will pop out. The pieces aren't held in by anything. You want to take off the pieces on the opposite side of the reduced end so it can slide into your 6"-4" reducer...hard to explain but you will understand once you look at it. These pieces are taken off so the ducting will fit.

At this point I attached the 6" adjustable piece to the 6"-4" reducer, and the reducer to the 90' 4" adjustable piece like so.

The 6" piece slides over the side vent on the front bumper perfectly. I slid it over the vent (with everything together) then manuevered the ducting with the adjustable 4" piece to attach it to the starting collar that was put on earlier. I pushed all of the attachments together as hard as I could so they didn't separate and sat back and enjoyed the easiness of the project. Total cost was $21 I believe. I coated it in some cheapo black paint for now so it isn't as obvious.

What are you going to do if it rains. You can always run a swicth to keep your temps down. Also vents in your hood.

Vented hood is going on in the spring/summer but that wouldn't solve the high intake temps very well. Run a switch to keep temps down? Not sure what you mean there, I am talking about intake temps, not coolant temps. Rain shouldn't be a problem, my filter will still be in the engine bay and the little bit of water that goes up the ducting shouldn't hurt it

 

[canada4g63]

Sorry I miss read on the intake temp. You can run e85 or methanol's. Maybe heat wrap your down pipe and intercooler piping on the hot side of it.

Already on e85 Sure heat wrap on the downpipe and piping may help, but intake temps will never be near ambient without doing something like this and sealing off the filter

 

[TSiAWD666]

Nice engineering.

 

[RipperXX]

For HDR (home depot racing) that looks pretty darn good.

 

[constant_proj21]

Any installed pics? For some reason, I'm having a hard time wrapping my head around where it actually ends up.

 

[RipperXX]

My guess was from the SMIC location going up and "giving" air to the filter element from the underside. Still it's not sealed unless you build a box, or can around it. But far better than the stock can and snorkel setup I bet.

 

[urmomsaniceguy]

Can't wait to see the final outcome. I've been looking to do somethong like this. Or I was just going to cut more of the number to expose more intercooler.

 

[gofer]

This is pretty damn good, hopefully it does what you designed it to do and only time will tell. Summer here we come...

Caleb, is this the shopping list then?

- 6 in. to 4 in. Round Reducer or Increaser
- 6 in. 90 Degree Round Adjustable Elbow
- 4 in. 90 Degree Round Adjustable Elbow
- 4 in. Starting Collar Take Off​

 

[CrawlinZX14]

I plan to do something like this, but I intend to make an airbox that is sealed over where the SMIC goes on my 1g, and duct air from the fog lamp opening up to it. So i dont have the heat of the engine bay to contend with, and I get clean air from the front of the car. But that will likely not be started until spring.

 

[blkgst97]

Looks good! wherever did you think of such a thing haha

Close, that last piece is the only one that is different. The piece I bought is exactly like this one except 4"

Shop IMPERIAL 6" Round Start Collar at Lowes.com


I kept the receipt so I could post up the part numbers for each one but it seems to have disappeared So pictures and links will have to work. Thanks for posting up the links though, I will add them to my original post

That's the plan for mine as well, but you will see in my pictures that I may have some trouble doing it because my filter is so large and hangs over the edge where people usually end their ducting

Haha I tried to find that pm from you but it disappeared so I just winged it You used all 6" didn't you? I never liked the idea of cutting a huge hole in my engine bay so this worked out better for me.




And on to more pictures of it installed.

It's cutting it close here when the steering wheel is turned so I need to angle the piece a little more for more clearance. Didn't rub while driving it yesterday though.

Yeah I used straight 6in. The hole was kind of a pita to cut but it looks good, and more of the air is getting directly under the filter. Yours looks good tho. For anyone wondering on a cooler day temps at maf were ambient and if it was warmer out I saw temps drop to ambient by the end of a pull. The faster you are going the more air is forced up to filter so imo it is worth it. But I also have a box around my filter so that might help out also. Pics are in my profile for anyone interested.

 

[CrawlinZX14]

But no one said you have to end your box at the frame rail. You are custom making it so you can simply make it longer to fit your air filters needs. Or you have the other option to get a different filter. Personally I was thinking about getting one of the bubble looking filters that's only a few inches deep. I plan to start this project after I fab up a battery box to relocate mine to the trunk.
