Spark Plug Renewal on Alfa Romeo 2.0l Twin Spark Engines

Alfa Rocker Cover

On CF2 & CF3 models, unscrew oil filler cap. Remove upper rocker cover using a ‘ribe 6 key’ to undo the four securing fasteners.

Alfa Romeo TS

Unfasten all concerning route clips down to and including the lambda sensor and air conditioning unit (if present).

Alfa Spark Plugs

Carefully pull the plugs with leads attached, off of the four spark plugs. On early cars these will be on the opposite cylinder while on late cars they are on the same one.

Alfa Coil Packs

Undo the 5mm socket heads that secure the whole coil pack rail, noting the earth lead on the right hand side of later cars.
Carefully lift the coil packs off of the spark plugs.

Alfa TS spark plug hole clean

Clean out around the spark plugs as it is not Tom Jones for oil to be in the holes, due to careless filling.

Remove spark plugs and replace.

Alfa Compression Test

If you need to do a compression test only remove the left hand spark plug from each cylinder.

Torque Alfa Spark Plugs

Torque up the new spark plugs, large ones to 30Nm and smaller ones to 10Nm.
Replace coil packs making sure that the flying earth lead is attached on later plastic rocker cover cars.
Push on plug leads correctly.
Connect route clips, lambda sensor and conditioning unit (if present).
