OBD II Questions

im wanting to put ram air kit on my jetta or intake, i already have a cam and exhaust, wanting to get good sound. Ive heard that the mass air sensor on obdII cars have to be "tricked" out or other wise the amount of air going into the car will confuse the ecu and make it run like shit.if anyone knows some good info about the best way to do this let me know.

I don't think so...
What kind of intake have you got?

im either looking at the eurosport thats all chrome, or the midknight air bath/ice box:bloated: :devil: :smoka: :frog:

Ok, I don't think either of them would mess up your MAF. Just remember to reconnect everythig.
Anyway, the AirBath kit from MidKnight Motorsport doesn't come with a filter. Oh, and they are closing down :(

I like the Neuspeed and Eurosport ones myself. I have had cars come into the shop running like shit and I find that the oil from the air filters cover the sensor in the MAF and give the ECM a really high reading. The high reading makes the ECM think that the car is going up a hill (high engine load) and it will just dump gas into the engine, which will then burn out the Cat. Some cars the MAF is about $350 and the old one can't be cleaned. If you do buy an air filter, get a foam filter that does not require too much oil. Also, the filtration of a foam filter is a lot better then a K&N style filter. Next time you have both style filters in you hand, hold them both up to the light. You will see light though the holes of a K&N style filter where the foam style you can't. If you can see small holes the dust and dirt can come in, and that is bad for the engine.

Good luck,
