Air intake guide

I thought I would write a quick summary for you guys on the possible air intake modifications for the 93ss. A couple of quick things you need to remember, first off almost all of these with the exception of the drop in filters HAVE been reported to throw the MAF censor. The result is a CEL, and the car will go into limp mode. Second off, you will see little to NO performance gain from modifying the air intake on this car. All performance gains must be done via software. Changing the air intake will allow for a more "sporty" engine sound, and will give you the "psshhhh" sound from the BPV. This is a bypass valve, not to be confused with a blow off valve, it still sounds good however. I have some audio/video clips of some of them, I'll upload them as I go.

Here they are:

- Speed parts open air / BSR open air (same as speed parts basically): This product was removed due to problems in the high RPM range. As of my knowledge the manufacturers are still selling them, however most resellers dropped them. The bug can be fixed with a software update that most newer cars should already have, if you have a 2k3 you may need to have the software update put on. http://www.elkparts.com/product_info.php/cPath/76_160_839/products_id/1217

- Simota carbon fiber: Very difficult to install, poor instructions. I contacted simota and received very poor support from them. As of my knowledge I'm the only person that has it properly installed, and that's because my mechanic friends helped me out. I purchased it from PFS, it arrived in USED condition. I posted on SC about it and was BANNED. DO NOT PURCHASE THIS PRODUCT.

- JR drop in filter: This product has received the best reviews from everyone that has it!
http://www.elkparts.com/product_info.php/cPath/76_160_839/products_id/449 *** soGGys recommended product ***

- S&B drop in filter: IDK anyone that's used it. http://www.genuinesaab.com/catalog/product_info.php?cPath=44_46&products_id=451

- Pipercross drop in filter: IDK anyone that's used it, but it looks pretty snazzy to me. http://www.elkparts.com/product_info.php/cPath/76_160_839/products_id/3312

- K&N air intake: They have a drop in filter now supposedly and an open air intake type set up, once again IDK of anyone that's used it.

- BSR drop in filter: IDK of anyone that's ever used it.

about the S&B, I thought I heard that genuinesaab has them made to a high quality specification that they have established, so they are probably actually just as good or better than the bigger more popular brand names.
I think there are quite a few people using the S&B cone filters on the genuinesaab intakes for ng9-3 ;)

One thing I wondered regaurding drop in filters... If I'm not gonna see any performance gains either way I go, I might as well go drop in. I really only wanted the intake for the psshhh (hah). Now most aftermarket filters I see are cones, but some of the drop in's I see for the 9-3 SS is the panel.. I haven't opened up my air box, but is the stockie a panel too? Speaking of air box, another thing I notced was the MAF is connected to the stock air box. Does that mean I would need to cut it off in order for it to work well with the drop in? Or could I drop in the K&N and put the air box back on top...? I have no clue!

Niether of you guys are on T8, you guys are on T7 ;) I've even had a CEL thrown with mine despite it being set up properly. No you do not need to modify the MAF sensor with a drop in filter replacement. It is like a panel, you just pull the stock one and put in the other one, and it allows for better airflow, and will give you a bit of the pssshhh sound.

Hahahahaha, oh yeah. It can be a nightmare. I think part of the problem with the "open air" type intakes is that you have to move the MAF sensor, and moving the MAF sensor at all can trigger a CEL =/. I drove with mine on for several months and several thousand miles before it went into limp mode. Dealership cleared the error code and re-seated the MAF sensor and we are going to see what happens this time around.

up here a MSU our instructor had told us that sometimes the oil used in some filters (K&N) can mess with MAF's but in my car I've had a open filter that I oil from time to time and that hasn't had a problem. granted mine is a c900 not a T8 car.

You are correct. On some air filters the oil will get loose and into the engine and damage it, it will also get on the MAF sensor throwing a CEL. You have to be carefull not to over oil the filters when you clean them. As of my knowledge this is a different problem than what a lot of us have been experiencing with the T8.

K&N hot air intake, it threw CEL on 03 vector when i tried it, jr is the best way to go

The diverter valve on this car is integrated into the turbo, unless you modify the turbo this can not be done (obviously). If you want the pshh noise, change the air intake. Also the part of the air intake that youre looking to modify with that "3 inch" modification wont do you much good. The air filter box has a tube goes down in front of the wheel well, and then goes to the very front by the grill, in order to pull cold air in. It's a really good set up, the only way you would improve uppon this is if you changed the entire tubing set up, meaning taking off your wheel well cover, front bumper, etc. I would only recommend changing the filter.

Notice how the Simota intake goes down in front of the wheel well, that hole is from the stock air box.

Does anyone have any information about this? I have a 2006 Saab and I love it but I want more power. I was told that a reflash may help with this but so far I have had no luck finding anyone who sells them for a Saab. ;)
I know there's an exhaust system and as mentioned in this thread, several intakes. Those are considered the basics for power upgrades.

ECU upgrades are available from Nordic, Maptun and BSR as far as I know. There's information currently being compiled as to the current available upgrades. The compilation should available before or right after the New Year.

if anything that will throw off the on board computer... theres like this little air sensor...( think thats what it is) that plugs into the piping towards the end of the pipe.... that ends of going into the turbo..that needs to screw in... and if thats out dangling ( or what ever u chose to do with it) im not sure ur car would like that very much... ill c if i can post a photo... or if anyone else can explain it better

also you guys arent reading soggys first post, if you want more power, any kind of power, You have to Upgrade the ECU, Via BPC most of the time. YOu WILL NOT gain anythign from exhaust or the intake only sound.
