Hello martin clack,

Hope you are enjoying yourself! When I could drive I used to love tinkering.

Can you tell me something please? I searched and it was not easy to find that much info' in the UK. I searched for the car instead of the plug in the end. It brought back the NGA plug, and I notice today it is for a 'e' and not an 'se'? Don't know if this makes any difference. I also saw some with Bosch plugs but, not your year or model number. It may be the plugs can take any extra thermal pressure in the sports model, which I presume the 'se' stands for? I did not have much time to search as I was going out and the computer froze on me three times, so I just grabbed a copy and pasted it.

Can you let me know if it is the correct plug/gap combination please? I can do another search.

Take care...................

Hi

the plug supplied by a Merc. specialist was a Bosch super HR 8DCX

Thx Martin

Just curious. In US the gap is required to be listed on the EPA (federal or california) emissions component routing sticker in the engine compartment (including '87 models) of all cars sold. Evidently not in England.
