1.9 DG Spark Plugs

[yetihair]

Hello,
I've got the van in the garage for a carb overhaul. (gutted that i'm having to get them to do it as I wanted to do it but I just don't have the time)
While they are at it i'm getting them change the plugs ,ht leads, dizzy cap and rotor. I got all the bits from brickwerks including the carb refurb kit.
I've just had a call from them saying that they aren't happy to fit the plugs I supplied as they are longer than the ones in there and they are naturally concerned that they might hit the pistons if they fit the new ones.
They are going to replace them with new ones of the same spec as it in there. When I decided to change the plugs originally I took a note of the plugs that were in there - NGK B6ES. When I ordered replacements from Brickwerks it doesn't give you a plug spec, it just says Bosch +1.
I've had a google and a bit of research and the NGK B6ESs seem to be the same diameter and reach as the Bosch W7DTC which are the specified plugs and the same diameter and reach as as the NGK BPET which are the Bosch equivalent. Obviously the only difference with those is the triple electrode so my question is what have brickwerks sent me? I'll find out when the garage give me the plugs back but it just seems a bit wierd. Does anyone foresee any problems with using a single elecrode plug? The van ran okay on them before.
Cheers

They are correct.
Spark plug technology has moved on somewhat.
Sounds like you had the wrong plug in, in the past.

Cheers for the response guys,
Kev, i'd read that before but couldn't find it again.
Simon, Are the bosch+1 a WR7DC plug?
I'll leave the new B6ES ones in and so long as its running okay I'll change them to Simons ones at the next service.

Yep, the 10 or so most common spark plugs just got numbered +1, +2, +3 etc.
