Custom CAI with paper filter
 

I put this together a while back. I made use of an S2000 stock air filter. The big paper cone flows more air than stock and fits right under the headlight. I insist on filtering my intake with paper elements. Was about $120 in the end. I tried to keep it as cheap as possible in case it didn't work. That's why I settled for a blue hose. It's been running perfectly since I put it on.

This pic is when I first put it together. Yes, I use hose clamps for all connections.

Parts list:
MAF pipe 3" Spectre 9405
Silicone elbow 3" 45 degree
Aluminum pipe 3" 2'
Silicone elbow 3.25" to 3" 45 degree - Pipe to filter
Air filter WIX 42726 (Honda S2000)
Clamp 3.25" T-bolt
Clamp 3" T-bolt - 3

I now use a 49003 filter (newer S2000s, bigger engines)

And did you tune for it?

Not exactly. I had been running Trifecta already. I sent a log file back to Vince and he said nothing needed to be changed.

Wow I have a hard time believing that didn't effect stft and ltft I thought the maf was pretty sensitive

I used a 3rd party tool to read the log files. STFT showed a spike hear and there in the -13 -14 area, but mostly nothing over/less than 10/-10. LTFT was -3.13 to -0.78.

Prior to the CAI, I saw spikes in the STFT just as high, but a 7.03 LTFT.

And nothing needed to be adjusted?? :lol: :lol:

What should the STFT and LTFT be at?

As close to zero as possible. A +/-2% total overage can be considered "acceptable" but as close to zero as possible is the goal.

Might wanna look into a hydroshield

Interesting, thanks for the idea.

I probably should use more caution. That area didn't look like it gets very wet, though.

I was thinking maybe, constructing something between the headlight bracket and bumper to divert water away from the cai filter. Looks good for that price.

Water comes in around the headlights in hard rains. I would never put a paper filter there. I have a Hahn that sits there and my hydro shield gets damp.

Thanks for the info.

Would a heat shield over the top of the filter protect it enough? The kind that is like half of the filter.

nice intake its always fun to build your own parts. Any shield has be better than nothing, u could always do some testing with a hose and see.

Does that filter have a 3" inlet?

just buy the hydroshield, they're 20$

They are not water proof. Adding something like this would just be added protection. Wonder how hard it would be to build almost like a ram air for the cai and have the opening connect Above the fog light.

It's a hair over 3.25". It took a little elbow grease (and WD40) to first get the silicone hose on the filter (3' to 3.25" 45-degree elbow). Swapping filters is easy now that the hose has stretched a little.

they're water resistant though and help it keep from getting soaked.

I just ordered a Hydro-Shield for an X-1022 filter, since it's the biggest they have.
X-1022 - 5'' filter, 6.5'' Base, 8'' Tall, 5.5'' Inverted Top
Pretty close to what I'm using.
49003 - 3.25" filter, 6.25" Base, 9" tall (filter section only), 4.5" top.

The set up looks not to bad at all

Thanks. Forgot to mention I also used an eye hook to secure the assembly. With this mount, it doesn't move around at all.

The X-1038 fits perfectly. Thanks again for the advice.
