Thought I'd give the plugs a quick check this morning...





Arse.

Ordered new ones but they prob won't arrive until weds/thurs.

I don't know how long they've been like that. It's been running fine since Oct with them in and not used the NOS for a good few months.

I don't want to think about cylinder walls and valves at the moment...

GaryB

Shown in the order they came out.

I think you can safely say they are trashed, I,ve got a set down the backstreet garage you can borrow if you need them before Thurs

GaryB

Anyone local to Macc got any spare std ones (BKR7E) I can borrow until the new ones arrive?

GaryB

That'd be dead handy if you're around?

If not I can use the MX5 until they turn up.

GaryB

I'm just surprised it still ran ok with no misfire codes being shown.

Nottm_S2

I'm surprised too

Do you think thats the extra heat from the NOS?

I've never changed mine to check, dealer has done it a couple of times i think

Daytona-Dave

The porcelain is missing on the two nacked one's, hopefully is gone outa the exhaust valves, you can borrow the bore scope for a look see for any probs, incoming PM

what would cause that to happen ? I'm thinking if the car runs fine with plugs like that then that would indicate a healthy engine surely. You say you havn't used nos for a while, would the nos have done that ?

GaryB

I'm almost certain of it.

Although why just 2 and 4 I'm not sure. I do know the NOS is running very rich though. Although I'd expect that to be cooler than if it was running bang on to be honest.
