The black circle shows what the restrictor plate is on the filter pipe...
The red circle shows where that restrictor plate is...
Hope that helps.

i wonder what the heck that does.
why would they restrict the flow of air before the turbo? to make the charge temps higher????

I did not know that existed. Probably they do it for CARBs. restrict the air flow, less air to compress causing longer time to spool up. i think that makes sense 
i am going to look into that

Its a "rubber thing" thats a pain in the *** to get on!! You need that so the filter will be mounted on the piping ( You clamp into the bottom of it ).

Would the Apexi filters that 2K_Teg work on the greddy turbo (referring to placement)? maybe those will help airflow. or maybe i will just use the K&N from my AEM CAI.

Re: Anyone cut off the restrictor plate on their GReddy kit? (falconGSR)
When I took mine off, I noticed that sound of the turbo spooling was noticeably louder. Took some friends for a ride the other night, and they all made mention of how much they could hear the turbo spool. Performance-wise, on my car, I didn't feel much of a gain. But then again, I do live in Florida, and all we get is hot muggy weather. Not good for forced induction.
It's just 4 spot welds. Took a dremel to it with no problems.

You know I was wondering what that was there for. I just wanted to get boosting so I left the thing on and forgot about it. Now I'm putting a bounty on that thing this weekend.

I cut mine off when dynoing my car. Gained 20hp!!!! from cutting it off. Nothing else done to it in between runs.

20 hp? really? Well I cut mine off also with a hack saw and it took freaking forever!! At the end, just used a screwdriver and a hammer to knock that piece off. When I took my car out for a drive, my turbo was definately louder and it felt faster (but I think it might be psychological based on the fact I could hear my turbo more). Definately cut that **** off!

Re: Anyone cut off the restrictor plate on their GReddy kit? (Arturbo)
I am looking at my filter right now, and see what you are talking about. But i am also looking at my K&N and they are almost the same. they have a wide bottom but then close in to fit the pipe. I agree though that the filter does look a lot more restrictive than the K&N. I am debating on what to do. If you remove the "restrictive plate" than what is used to hold the filter onto the charge pipe?

****. I TOTALLY FORGOT I HAD THAT THING!
I'm going to cut it off.... but would it be that much of a difference to merrit a retune, or will I be safe?

Definitely take that plate off and you'll notice that you'll hear the turbo spool a lot louder. Install a 2.5" dp and it even get's louder.

Art, you really think it would be a PITA to use an Apexi filter? I really want one for my Greddy, but if that wouldn't work well, what about the fully stainless steel Blitz filters? I know they don't flow as well as the Apexi, but I doubt it would matter much with a turbo. BTW, did the Greddy kit you just installed come with this restrictor? I'll check tomorrow if I have one.
Anyone here use a Blitz filter?
