I've recently purchased a 1999 Audi A3 1.8l turbo 5spd man as a daily driver and I plan on squeezing a little more power out of the very capable engine. As the car as only done 114,000KMs (not miles) I don't have any worries with the engine. My first mod is hopefully going to be installing a pod filter to replace the factory airbox. As I've seen the Honda S2000 pod seems to be a popular choice around here and I was going to follow suit, however I have a few queries. Pic 1: As you can see the engine is completely standard. Pic 2: Closer up of the airbox Pic 3: I believe the item I've circled in red is the MAF filter, however I don't know what the other two sensors are (circled with blue). I'm guessing they are important and if I remove the air box I have no idea what to do with these two leads. Also if the pod is to simply bolt onto the intake to the turbo I will need to remove the MAF housing and I don't know where the MAF will plug into. To me it seems that I'm missing something and I will need to make additional purchases like a new MAF housing. Basically my question is, do I plug the pod directly onto the turbo intake? If that is a yes what do I do with the three sensors? Any help would be greatly appreciated!
