Hi Guys,

Just getting things ready for the rolling road and putting the car back together....

As i have removed the standard FPR and the cabon canister and what not, there are now extra ports on the top of the manifold, do these need to be blocked off or are they ok to vent to air?

 

Bump...need to know this asap

 

If on the manifold, you need to blank them. The MAF measures airflow, and that's positioned before the manifold: any hole that allows air to be drawn in after the MAF will upset the metering...which is bad news.
