$20 DIY Open Induction Cover

Hey All. Here's a neat little project we did over the weekend on Abandonhope16's LGT.

It's a DIY Open Induction Cover similar to the one maufactured by Blitz (see reviews section) but made for under $20 .

It dramatically increased the BOV sound and gives a nice subtle "breathing" sound upon throttle.

Its sort-of like a refined and functional "Hog-zaust" for your intake.

So if your feeling adventurous and the silencer removal doesn't quite do it for you, the instructions are imbedded in the photos and feel free to query..............ENJOY!


EDIT: The sandpaper if for roughing up the aluminum surface to prep for the epoxy (oops forgot to include that).

Wow nice work. What does the Blitz cover retail for? And what brand Filter are you using there? K/N ?

Thanks .

Not sure but, I believe the Blitz goes for about $125-$150 minimum.

The filter is an AVO (I think, made it for my brother's car so I'm not 100%)

Blitz sells for about $130 with the filter
Mine is an AVO.
Sounds great, but I'm wasting gas b/c I'm flooring it everywhere.

nice, but it's no hogzaust :P :P

LoL so this is what you guys were doing on Saturday instead of taking out the cubby!? :P J/K looks good man. Wish I coulda stayed to hear you drive off on Monday but work beckoned.

Is the advantage just pulling more air through? I would think that you would be pulling more hot air from the engine bay, maybe a heat shield of some sort on the right side to help.....

Nice fabbing!

^^^Thanks.

We are considering some kind of duct-type work that would bring air in from the "drug smuggling" area below the filter (where the CIAs go). A heat shield would be included (just gotta find the time).



BTW I love your screen name and avatar.................."Hello. My name is Inigo Montoya. You killed my father. Prepare to die."

One of the best movies of all time!!!

Nice job, but I have a question. (I was the kid in the back row at school everyone wanted to kick because I always had a question, LOL)

The slots at the top for the AB clips; Do they allow unfiltered air past the element? Also, if you bolting the assembly in place, could you do without the clips?

BTW, I have an idea to get some cold air over there if your interested.

Me Too!

The filter has a complete seal to the housing and is held in place by the pressure of the face plate (alum and ABS) via the clips and bottom bracket. Everything forward of where the filter meets (seals to) the housing is completely filtered (essentially we have a stock config. from the filter back).

Also, if you bolting the assembly in place, could you do without the clips?

No, the clips are a critical part of holding the cover onto the housing. Without them the only point that would truely be attaching it would be the bottom bracket. The engine is on rubber mounts that allow it to tilt slightly upon throttle, so the cover would seperate from the housing easily under those conditions (the piping to the engine is not fixed either, it has give in all directions that act as a "suspension" for the filter assembly).

BTW, I have an idea to get some cold air over there if your interested.

I'm always interested in a good brainstorm, hook it up.

Here is the cold air set up I have. I used the factory ram air scoop. You could build a box or an air deflector around the element, then cut up and redirect the air from the factory scoop.

You'd still have the "smugglers bin" too!

Nice job.

If you check about half way down the walkthrough, you'll see pictures of the snorkel in place (which is how the setup actually is, the final pics were just to show the comparison to the Blitz pics). We are planning a "1/2 duct" that goes from the snorkel to the cover, but only on the engine (right) side and top. This would get us air from the factory snorkel and the "smuggler's bin" area, while isolating from the majority of the engine compartment (we're also trying not to alter factory parts). Something similar to what you have done but actually connecting the snorkel to the baffling you made.

Questions:

You have the modified snorkel but it appears that the CIA is sealed to the "smuggler's bin" and the snorkel isn't contributing to the air flow into the filter, is this to cool the piping?

What was the material of construction for your baffling?

You should prefab these, with a heat shield, and sell them for $75. I'd but one.

I'm sure I have enough supplies left over to make you one.

It would have to wait a while though, I'm preparing to defend my ChE Thesis and free time is a scarce commodity these days.

We could do it sooner with just the OIC, but the heat sheild will need development hours that I just don't have right now.

If you (or anyone else) is interested, let me know and we'll work something out.

If you look close, I sealed or enclosed the element inside the smuggler bin, isolating it from engine compartment air. The snorkel has a tube that forces cold air in right at the base of the AF element. So it is basicly pumping cold air into the smugler chamber, directly beneath where the airflow goes into the intake.
