Spark Plugs Question

[Deleted User]

I was looking for Bosch FR 7 D+ spark plugs (electrode gap 0.9mm) for a 1997 Nissan Almera (1.4i).

I have been sold FR 7 DC+ with the label "+8" on the box which was listed as being the right one for the vehicle. Electrode gap is 0.9mm.

I'm sure they're the right ones but just wanted to double check if anyone knows??

Current plugs in the vehicle are NGK BKR6E but a few places don't seem stock them in a pack of four for some reason and buying individually costs a lot more. So figured I'd give Bosch a try.

FR7DC+ is equivalent to BKR6E

Thank you, I just replaced them.

I have looked at the old ones and can't tell whether it's normal wear or may indicate a problem. Haynes says that a light tan/greyish brown deposit on the used plugs is normal. Can't say I've noticed any problems with the engine.

The engine has done 115k (about 40% of that is from motorway journeys). Here are the photos:

Those old ones look absolutely fine. They're a little on the "light" side, but certainly not to the extent that would suggest problems.

The colour is good but can't see the wear from that angle. Re the gap you can always check and adjust the gap with some feeler gauges.
