Hey guys i heard that putting an open air intake can make your check engine light come on! I have a 1999 9-3 turbo that i wanted to get an intake for but i was wondering if any of you guys had this happen when you added your intake! Thanks for the Input!!!

Since you have the T-5 ecu you will be fine putting a open intake filter on. the T-7 ecu tend to throw the codes because of the MAF sensor.

I've had an OAI for about a year in a T7 with a couple check engine lights, both for unrelated issues. I think you should be just fine...

Why do you want to put on a open air intake if I may ask?
Powerwise the stock intake with stock paper filter flows more then enough air for +400hp:roll:

Well I notice increase in acceleration when I installed my GS intake. Wasnt much but if its for sound it sounds awesome.
The sound makes it sound faster but it's not. Listen to what Pade is saying. He knows what he's talking about.

Regarding the sound, yes it's nice but you can get a better sound with the sport exhaust.

I guess people like the noise more than its practicality though. If you like it for the sound, go ahead and buy it but it won't add to the performance; the sport exhaust on the other hand would ;)

The sport exhaust will be necessary as well if you plan on a tune in the future... but you won't see much performance increases with the exhaust by itself, either. Get both! Great sound and a nice turbo whoooosh to go with it.

"Since it's a T5" is irrelevant. TONS of people put an OAI on their T7 cars without problems. Gotta represent the T7, yo.

right but im just saying with t5 you could disconnect and not have an intake pipe with filter on and all and it would not throw any codes. try that with your t7. lol:lol: seriously though i was just saying you can throw a pipe and filter on there whether you make it yourself or not and not have to worry about any cels really on a t5 where as on a t7 you gotta take more into respect on making an intake

Very true. Just trying to make myself feel better. I swear, if a ladybug smahes into my windshield the CEL will pop on.

It doesnt make it sound fast, it just sounds loader. I defiantly notice a difference, but I would have rather saved the money and use it on an intercooler.

Okay, the sound is nice (if you are in to that) but remember that most of the open air kits out there are actually really bad performance-wise. I'm talking about the kits where the filter is located in the engine bay right next to the hot engine. Even with these so called heat shields you will probablyend up with much hotter intake temps then with the stock filter box.
IF you must put an open air intake, I would build it up myself and place the filter behind the foglight in the frontbumper. This way you will allow it to suck in cooler air and it hopefully won't give you negative performace gains.

It would be nice if AEM made one of their "cold" air intakes for our cars. I had one on my previous car and it was super nice and went right down into the fender. Someone in California should contact them to use thier car as a prototype

I agree entirely, there was a bit of a difference in power, but the sound was and still is amazing.

I agree with you on this, the temperature is a bit higher with the GS intake I have, when I did a test a while ago , there was a 41deg increase over the ambient temperature right next to my filter after only a 5 mi drive (a pretty hardcore drive). We all know that the difference between driving in 50deg and 90deg weather is huge.

I do think that the less restriction achieved by the open air still yields benefits, but I hate the extra heat, so I will be putting on a hood scoop of some form eventually, and wrapping my exhaust is on my to do list as well.

You should just put that in your signature. You must type that 5 times a week.


Ansyway, I had a great time with my GS OAI. It made neato noises, and the filter was washable. It was on my 2000 for over a year with no problems.

9-3sleeper - good work with some actual measurements - to be honest I never knew it would be that bad:eek:
Palmer1980 - I'm glad you had a great time with your filter - I sure feel like I'm missing out on a whole world of fun there.
