So I am putting a cone filter into my 99.5 audi a4 1.8t.
I have done this before on a 2000 but i think the 99.5 is slightly different...
So i took out the airbox removed all the plugs and now im left with the MAF plugged in right after the cone, but there is still an oval shaped sensor that was inserted just into the top of the airbox with 2 plugs coming out of it. My question is what is this sensor? and what do other's set ups look like with that sensor. I just don't want to finish this install and find out i cant run it because of a check engine light. Thanks.

that is your ICM.. leave the heat sink on it and let it hang or tuck it out of the way.

Done. I can hear the turbo and DV so much more now.
