I noticed a silly difference regarding the cams cover and the spark plugs cover on Q4 engines.
One seet up is with 'Alfa Romeo' logo on the cam cover and the 'Turbo 16V.' on the spark plugs cover.
The other is with 'Alfa Romeo' logo on the spark plugs cover and the 'Turbo 16V.' logo on the inlet plenum.
And a third one with just the 'Alfa Romeo' logo on the spark plugs cover.
Is this related to the Q4 series {nb - wb} or is it just a coincidence?
