SES Light after Header Install...

BTW, the driver side rear O2 is a PITA to plug in because its pretty far up. 
what your looking at is probably the stock air gasket, not a restrictor plate. the stock air gaskets have the hole diameter the same as the air tubes.
As for the SES light, it kinda grows on you after a while. You seem to mind it less and less as your mod list increases.
and your right, the SES light does grow on you
, i got mine for the !egr and rear o2 sensors. still havent edited the codes out.
