I've been seeing this on random forums lately, but people tend to get CELs when they upgrade their intakes and some don't get CELs. Anyone got any ideas on what the cause would be?

usually has to do with the MAF sensor.

also, you just need to reset the ECU by disconnecting the battery when you're done so the car gets used to the new air reading.

Yeah, the MAF Sensor usually is the cause. I see it on both xB2 and tC forums. They do the ECU reset, but then they still say a CEL goes on. Whether I'm modifying my intake to go turbo or modifying my intake and staying N/A, I hope this problem is user error and not because the car just hates modifications.

always user/installer error.

i had to reset the ECU like 3 times before the CEL went off..

Haha, good. Looks like I won't have to worry
