Home Depot of course :D in the insulation section. I didn't get the thick roll but the thin roll. It blocks out heat very well. When I'm working in attics during the summer and the inside of the roof is lined with that then the attic is alot cooler.

Thank you sir.
 
I think the most interesting thing with mine is that I managed to make a CAI on a long route setup. I also routed my whole fmic myself, and I had to route it a certain way enable the filter to fit in there. The filter is $20 from autozone, its actully a good filter. Its rewashable and has inserts to accommodate a 3", 3.5" and 4" diameter pipe. I will stil make another splash guard for the area of the fascia that is directly below he filter as I dont have a splash guard there now. The pipe is made of PVC from the DSM Tuning shop, or Home Depot is what its really called, its a 4" to 3" 90* coupler. I took a 4.5" maf adapter and wrapped a generous amount of electrical tape around the maf ( until the 4" end of the pipe fit snug) and the used some clear outdoor caulk around the edges. Then at the 3" opening end I obviously bolted up the filter, which n the 4" setting fit perfectly on the OD of the 3" pipe. Then I had to do various cutting and manipulating of the intercooler piping to get everything to work but it finally did.

Looks ghetto but it really does work

Kinda dirty, eventually when I have more time I will paint up the pipe

I think that this is the first CAI with long route piping that I have seen. Its very possible it just takes a little messing around with things.
 
Good job and I know first hand it works but for me living down here in 'Katriniana' where it's a hurricane one hour and bright and sunny the next I never know when it may rain plus I like to get my boost on in the rain and get sideways:D .

It's always been HDM to me, or Home Depot Motorsports. As u know people with all kinds of cars that get stuff from there for their cars. Either way good job. Now paint it black and be done with it :thumb:
 
well as soon as I saw JessGSX's CAI, I knew that was the route I was going with. Cheap and effective and looks pretty darn clean.

I was running the K&N fpik, so obviously this type of filter would not work. At first I thought I could use the round 3" inlet filter I had in my other GSX. So I switched the K&N fpik to the other GSX, and went to HDR to purchase the parts.

JessGSX used 5"-4" and 4" pvc pipes. I figured since my filter is only 3" inlet I would get the 3" pvc pipe. I got a 90 degree pvc 3" pipe, one end is "male" other is "female" (definitely not the term used in the plumbing section of Home Depot ) along with a 4" to 3" rubber coupler. The rubber coupler attached perfectly to the generic ebay filter adapter. The 90 degree elbow also attached to the coupler with ease. Very secure, no play. Now my dumbass self didn't bother to bring the intake filter to the store to test out. When I go to finish the install, the filter did not attach on to the female end of that 3' 90 degree pipe.

The damn intake filter is 3" OD. And the female end of that 3" 90 degree elbow flares to basically almost 4". If I tried to attach the filter to the male end, it would not work, because the OD are the same. So back to HDR I go and see if they have a 90 degree elbow 3" to 2.5". NOPE. I gave up and just bought those sceptre filters at autozone for $24. Nice filter which includes adapters to make it 3" or 3 1/2". With all those adapters removed it is 4" and fit perfectly to that 3" 90 degree female end.

As for the results, WOW THEY ARE GREAT. My temps never went over 80 degrees. When warmed up esp. on a average sunny day here in cali, I would see 110-120 temps and thats just cruising. So just claiming what everybody else said before me, you definitely see around a 40degree drop. I can't wait to see on cold days.

Oh, and its CARB LEGAL, theres the K&N intake carb sticker on the MAS. :D

And before anyone asks, that is the SSAC 2g fmic kit, and that is an HKS Racing Type II BOV knockoff on a custom ghetto hacked wrx hks flange adapter. My vague review on the BOV here:

Pics from my first post don't work anymore. But i've had this on for atleast a year with NO problems, and yes i've been through hell and back weather wise.

I installed this a few months ago. Intake temps dropped quite a bit. I no longer have to worry about my intake temps raising as I sit in the waiting lane at the track, traffic lights, or the hot summer months. Oh yeah, it reduced my spool up by about 2-300rpm. I get full boosts by 4200-4300rpm whereas before 4500-4600rpm on FP3065 and 2.0.

this may sound stupid but what if u left the stock smic and just run it into the piping instead of the air filter? to much air ?
 
Looking good guys. Here my ghetto intake with the T70, sorry for the poor quality

thanks for the mad tight props yo! :thumb:
 
I want to do something like that. I'm going to try to find a 4" ABS pipe instead of PVC. I vaguely remember reading something about PVC putting off corrosive gas when it gets hot, but at the same time I doubt this extension gets hot enough since it's barely in the engine bay. Anyway, a 4" pipe will flare to 4.5" at the end, which will match my 4.5" OD filter adaptor. I'll use a Fernco 4" to 4" connector which is actually 4.5" to 4.5", only 5 bucks or so. Total cost for the coupler and 4" 90 should be less than 20 dollars, then it's just a matter of buying the appropriate filter.
 
Did you guys have to change any tuning settings with the degree drop. Also did you see any more lbs/min? I was busy mainly looking at the temperature, but I remember seeing 40lbs/min on 91 pump at around 20lbs, I will have to double check my log. But that definitely surprised me. This is on PTE 50 trim, stock motor.

This is something I have heard about also. Correct me if I am wrong, but don't you get the extra room for running the 4" tubing to the end by taking off the passenger side tire shroud? I might do it this way because it makes the engine bay look cleaner on the top. I also did it this way with my 14b but did not run into any clearance issues running 2.5" tubing.
thanks for the help

Although lb/min is pretty inconsistent, I definitely noticed an increase after the cold air intake. This would make sense too. If the karman (hz, volume) of air stayed the same but intake temps were reduced, lb/min would definitely increase as the air coming in is heavier even though it's the same volume of air.

Denser air.
Also when i do this im running it straight off the turbo into the fender lining instead of trying to do that 90 deg turn into that upper intercooler hole.
 
It let me advance timing because I was seeing 140 intake temps with my tubular mani and everything else.

I didn't log lbs/min after though sorry.

you just have to do some trimming thats all.
 
Especially on a small turbo like a 16g with a small inlet and cold-side, having denser air at the inlet of the turbo could make for a significant increase in power and boost holding at higher rpm at higher pressure ratios.
 
Just a word of warning for anyone making the same pipe as the original poster: The 3" Spectre tubing is a restriction along with a 3" filter and doesn't flow well.

I had my car well tuned with ebay injen intake pipe, and 2G K&N Oval Filter pack, running about 23 psi, and flowing between 34-36 lb/min of air on an e16g. I put the 3" adapter on MAS, and the Spectre tubing, along with a 3" circular air filter as the original poster. Air intake temps did go down, but the first time I tried to drive the car, when I accelerated the car bogged down. I thought I disconnected something and forget to plug it back together.

After some looking, it came out the setup was a restriction. I leaned out the airflow, and the car would only flow about ~30 lb/min with the original setup. Put the K&N filter pack back on, and was flowing 35 lb/min again.

This is not to say cold air intake don't work, they do, but they need to be done with 4" tubing and a large filter to work properly. In this case a 2G K&N filter even with high intake temps works better than the Spectre 3" setup.

O rly?
 
How is everyone connecting these huges pipes and filters to the 2g mas?

Where can I get that adaptor? What is it called?
