Hey guys, wondering if anyone has deleted the seondary air injection system on their m96 engine? (specifically 01 986 2.7) it seems my valve has done out, and i was wondering if i install a block off plate, if the car will run fine that way? obviously id expect check engine lights etc, but i plan on getting the car tuned and believe the system can be turned off with that but i may be wrong. currently valve is leaking and causing very low power immediately after a shift so im just trying to figure out if i should repair it or if its something i can delete without to much effort. Thanks for any help you guys have

Sai is an emissions thing so u can block it off without hurting the motor. Its my understanding that the row cars dont have it but u may want to double check.

From a 996 stand point, thats what i have, i not sure how a bad sai can hurt the cars performance? There is a change over valve that defaults to close. R u sure u dont have an additional vacuum leak?

Ill have to look into that and see then, i assume for the moment the valve is leaking because i have a too much flow code for the SAI. that said i also have one other issue to sort beforehand to make sure its not a symptom of a larger issue type deal. deleteing the SAI system also just seems easy to do and would net less possible headaches in the future i suppose.

It exists only to run for the first 30 second after you start your car to heat the O2 sensor faster. It will throw a CEL if you disable it, but serves no other purpose.
