The SAI is the mushroom shaped thing that comes off the manifold wooly. You don't have to blank it off if you don't want to with the Janspeed manifold.

Edit: This explains everything you need to know

Cheers shaun il have a look at that.

Just wanted to check before i buy one thats all.

Is there any other way to cover the hole without welding a plate over?Rather have sorted before its fitted because it will be a real pain to do once its fitted

i cant remember,somewhere out of t.v paid 200 for it but the quality was very good and as i had a de-cat and system i honestly felt it made a real difference (i had cams also but standard inlet with viper filter- ahhh the 1.4 16v days )
