DIY: Short Ram Intake for the R18 (Ghetto Fabulous)

[Mikey6p]

Foreword: Follow this DIY at your own risk. It's not hard, but you need some dremel skillz. Is this intake going to give you 10whp? Probably not. Is it going to make your R18 sound like it has some cajones? Yes. Yes it will.

VIDEO(thanks CrazyJim):



Basically, you are hacking out the OEM MAF holder to force it to accept a cone filter

Required Items:

• Phillips Head Screwdriver
• Standard Screwdriver
• Dremel
• Cutoff Wheels for the Dremel (preferably the metal ones)
• Sanding Bits for Dremel
• 10mm Ratchet, and Extension
• 2.5" to 3" silicon coupler
• AEM air filter, 2.5" opening

Procedure:




The coupler you are going to need. Available in the "import modification" section of your local Pep-Boys or Autozone or Kragen



Pop off the clips holding on the airbox lid. Disconnect the MAF wire, and take off the airbox lid and remove the air filter.



Pop off the airbox inlet hose (blue)
Remove the two 10mm bolts holding on the box (green)
Disconnect the hose clamp (red)
At this point, you can pull out the lower part of the airbox. Use some strength and twisting, the nipple in yellow has to be forced off. You can throw this assembly somewhere, you won't need it.



Loosen the hose clamp on the left, so that this hose may be rotated.

Now its Dremel time:

Remove the MAF from the lid, and place it somewhere safe and clean


This is what you have to start with. Your first cut should be to free the general MAF holding area from the bulk of the lid.


your next series of cuts are going to separate the MAF tube from the rest of the bulk around it.







This is more or less your finished project. Make sure to trim down the ridges(Red) and the former wire clip area (green) and sand these areas down so that the coupler can make an airtight seal here.



Slide the coupler onto the filter, like so.


Now assemble everything. The easiest way to do it is to slide everything together in the engine bay, maneuver it so it sits properly, then tighten everything.

This is your final goal.









Ever need to go back to stock?

New lid isn't expensive


17211-RNA-A00 COVER, AIR CLEANER $ 15.36


Worried it doesnt make power?

Makes just about the same power as an Injen CAI

Original Dyno with Injen CAI


With home made SRI (oem maf housing, couplings, and AEM dry flow filter) I used an apexi filter for the dyno run though. The low run is with the Air Conditioning turned on.










Summary:

Injen cold air: 111.11 hp / 100.94 tq
Short Ram: 110.82 hp / 97.53 tq
Short Ram with AC turned on: 100.69 hp / 97.53 tq

Enjoy.

I feel a difference in acceleration. and it reduced my gas MPG because i redline all the time now haha... but thats my fault.

saved me $250...

[GETxERxDONE]

you were supposed to make me one oh well, i guess ill deal with my cai lol

nice write up

[Exeon]

nice. it's like a mini x-intake style diy sri

do r18's maf section have vanes too?

[Mikey6p]

No vanes in the r18.

[gabien01]

nice..

[k__dam]

is that red thing over your filter a heat shield? how much was that

[GETxERxDONE]

its a hydro shield, they are about $30 i beleive

[k__dam]

oh ok, i've always thought hydro shield was for cai, is it recommended for the sri as well?

[GETxERxDONE]

either/or depends on what climate. what i would do is next time it rains really hard check your engine bay and see how wet it is after youve drive for awhile, and through some puddles.

[atallah24]

pretty impressive makes u wonder if a CAI is worth all the extra money....

[Mikey6p]

the hydrosheild also acts as a prefilter. Keeps the filter cleaner.

[GETxERxDONE]

^yeahthat

[ErichPryde]

very nice writeup!

[Ronnn]

pretty impressive

[raybyduhbay]

im guessing it wouldnt....but you can just slap on a stock filter lid for inspection....its 15 bucks.

moved to the Engine section. I meant to do it last night but got sidetracked with a less-fortunate member.

I like the intake!
