i had this with my sti2 after a bonnet change.Originaly i had the same bonnet as you but with a mini scoop over my apexi cone filter.I then fitted a carbon facelift bonnet with no scoop and my engine check light kept coming on.

Remember when your stationary the temp of the air under the bonnet increases as there is no cold air being blown in from outside like when your on the move.

I cured it by removing the cover off the bottom of the right vent on the bonnet.
Easy way to find out if the filter is being starved of cool air and thats to wait for the check light to come on then go remove the right vent and drive with it out and see if it cures the prob.
