From: Brunei. Do u know where tht is?
Labop... Thanks for ur reply... But i am still unclear about something...
Attached is a diagram of the system...
I am sure u have to remove the yellow bits.
What about the blue bits? Do i have to remove the VFAD actuator? or just the hose connected to the actuator... Can i leave the blue hose in place?
Also do i leave the solenoid valve plugged in? And other than the hose running to the actuator, are there any electrical connections plugged in? do i take those out too?
Thanks for your help... Want to be sure before i go and do it

^^ what zoom said ^^
Once the VFAD is electrically unplugged and the first hose line is cut, the VFAD is effectively disabled. But it's still in the way, probably (IMO) disrupting the airflow wether it's open/closed. The actuator is directly fixed to the VFAD duct (I re-colored that area green). So they come out together.
The yellow colored hose will have to be removed. It's particularly difficult to get it off of the end (area inside the red box). I put a red box around the plug that will need to have a cap put on it. If you have medium/large hands, it's not as easy to get to as it looks.
The blue bits, are made of soft tubing and metal hard line. But both are easily removable. I wish I'd been able to point to that image earlier, would have made explaining things a lot easier. Good find.

i agree with zoom.... i mean... we all three just got this intake and are having the same issues.... a little fishy if you ask me... im sending them an email right now, and the rest of us should do the same.

I had so hoped i didnt have to remove the green bits... Removing the bumper would be trouble some... After looking at the shop manual, i find that it's mostly screws... Only 2 nuts.. I havent got any tools... So whenever i access the ECU, i open the nuts with some pliers lol... Hoping this will work later

ok guys, i just got back from my dealer... they told me that the oil in the filter could have fouled the MAF sensor. they dont know if that is the issue or not. the mechanic told me that it looked fine. but would order me one anyway. they have one on order and i will get it early next week. i took the umnitza off and put the stock airbox back on. the mechanic told me to try to disconnect the battery when putting the umnitza back on, then reconnect and see if the ecu reads it better...
so, i will try this and let you guys know....

PS.... i put the umnitza back on and NO GO!!!! rev it to 5k-6k and get BAD sputtering (enough to hear it out the exhaust)!!!! and then the revs drop all the way down to 0K and, of course, the damn thing stalls! not good umnitza....... my dealer actually told me to leave the intake on so that when i bring it in, then they can try and figure out what is happening!!

well... here is the update... i took my 8 to the dealer yesterday with the simota on and the stock air box in the trunk. they have decided that the simota is causing a vacuum and pulling oil up through the intake, fouling the MAF sensor. they drove it this morning with the simota on and said it drove like ****. put the stock box back on and said it drove awesome... i told my buddy, who is the service dept. manager, to take it home tonight and see if he has anymore issues with the stock box on.
i can't understand why this intake would cause this......... can anyone confirm or deny this?

hmmm i have no clue mine never had that problem i don;t see how oil could get on the MAF unless oil was somehow going backwards through the intake beings that the pcv would be located after the MAF that makes no sense. sounds more to me like a clogged filter have you taken it apart and made sure filter didn't have plastic or anything on it. mine didnt' but mine was completely assembled on delivery

me and my buddy Vince (Project87GXL on TeamFC3S.org) about the problem and he thought it could be possible that your MAF may not have been on completely or an airgap around it or something leaking after it OR one of your vac lines open. all that is possible make sure all is tight with NO gaps and make sure MAF seals right and try again just an idea

my car is in the hands of my dealer right now... they put on a brand new MAF sensor this morning, with the simota on (ran like ****)... put the stock box on (ran fine)...
they are saying that they THINK that the oil IS coming through backwards getting oil on everything... they had to clean it all out today.
i emailed umnitza and there is a possibility that there is a design issue. they are in contact with simota and will contact me hopefully tonight.
this is the email that they sent to simota......
Louis,
I need an answer TODAY as to why you think (or why the engineer's think) there is a problem with this RX8 intake. This is the second time we've had this type of an issue come up (the first was with the Mazda3 when your engineer's inexplicably changed the design) and we got CEL issues from another Mazda car.
Now, if it's a customer install issue, I'm going to support the customer to make sure they did the right thing, but I need some confirmation from Simota that all other possibilities of CEL problem (Check Engine Light) due to this intake are exhausted. See below - the customer is upset.
