I just wanted to check something.
I had some trouble getting all the plugs out from our Peugeot 306 1.4 (1998) due to the position of the injectors/air inlet (big plastic thing which air filter goes into and curves down into the the cylinder, next to the plugs. I think I got 3 out, but couldn't get all 4 out.
Anyway, due to that being in the way, and not knowing how to remove it properly, I asked a garage to change the plugs when they were doing something else. I asked for them back so I could see their state.
This was a while ago, and since stopped using that garage due to being unhappy with their work. I'm preparing to change the plugs again (myself this time hopefully) and went to my local factors who supplied me with 4x NGK BKR6EZ. This is a single electrode plug, and is listed as the correct plug for this model on NGK's website.
The issue is though, I'm now looking at the old plugs and noticed that they're double electrode ones - specifically NGK BKR5EK. Whilst they seem the same size, I'm a bit surprised to find double electrode plugs were used before - especially when NGK don't recommend them for this engine. The previous service would have been done by Peugeot themselves, so the plugs are either:
1.) Fitted by Peugeot themselves, even though they're not the recommended ones 2.) Changed by the garage, but the wrong ones were returned to me 3.) Not changed by the garage, and someone else's plugs returned meSo, which seems the most likely? Are these plugs actually okay (ie. would Peugeot have fitted them), or was it 2.) or 3.) then?
Finally - any suggestions how to get the plugs out - I'm wondering whether an articulated plug remover would be useful. Before I used a socket set with a plug socket on it - but I think with an extender, hence not being able to get into the gap between head and air inlet stuff.
Thanks
