in some makes like vw if u put on a intake or a slip on exhaust ur sensors start to break...meaning veedubs suck...
for the people out there that put thse things on did uhave any problem at all with sensors or anything...ive herd some people had trouble with idling how did you guys fix this these problems?

 

no problem with intake or exhaust.

turbo is fine too, but it depends on your choice of fuel management systems if you get any christmas tree lights or not.

searching will fill in the details.
