Not another spark plug query

Post by TONYT25T25 »

Just like the oil one, all will be familiar with. Looking at changing plugs, but last time the ones that were recommended by a dealer were several mm longer into the chamber than the existing ones which put me off. Basically looking for upto date recomendations ie three prong or single, depth and make. Tks.

A quick browse in the Haynes says -
DF / DG / DJ

For ignition coil with green sticker =
Bosch WR 7 LT+ set at 1.0 mm electrode gap

For ignition coil with grey sticker =
Bosch WR 7 D+ set at 0.8 mm electrode gap

My user manual says
VW No 191 905 450A
Bosch W 7 DTC

Brickwerks quote - Bosch W 7 DCO
They also show another plug type but no Bosch plug number is given.

1987 Electrics and a DJ engine.
Maybe one day I might get it finished

Thanks, so much choice is what made me look a bit more closer, i suspect more depth into the chamber gives a better ignition but was concerned if that may make contact with valves etc.
