Phil, I think those are fakes - I think I just fell victim to the same scam. Look at the NGK logos on the boxes - some have the "R" circle next to the NGK logo, others don't. The yellow is different colour on each box too.

I've just received a set from Greece (yeah, I know, I know... :oops: ), they didn't look right on arrival - only two had the cardboard tubes over the threads. The best thing I can do is to post up more photos so people are aware of the potential risks here.

I fitted ones that came in Yellow NGK and they appear to be iridium ones, so think you should be ok.

The "cold" NGK plugs 6700 & 6701 (I think) come in yellow boxes. Not really any cheaper. I ran them for a couple of weeks without issues, but swapped to the laser iridiums as soon as I could. Just have them as spares now.

Ooops, didn't realise this was an old thread....

Thanks chiron, very useful to have that feedback. Did you buy them from the eBay seller that sells from Greece? 13Black warned about that seller last year, I think I remember him saying he had a customer who also received fakes.

Good on you for spotting them before you fit them. If they were from eBay I'm sure you can get a refund through the buyer protection they have.

Seller name was chris_watel.

Ebay got my money back in full but the guys is still advertisng.

I've got both sets of real/fake plugs and will write a post on how to spot them soon.

Theres already a useful post on fake sparkplugs/how to spot them. Probably best to add to that.

I've added my images and info to the other thread. I may create one for the public side of the forum too as it could help future owners.

I'm also keen to get the dodgy suppliers exposed.

What people see first is the price, greater awareness of fake goods especially the Spark plugs and the damage they can do can only be a good thing.

My advice, always buy from a reputable dealer (such as us :P), While we cannot compete with the £50 Ebay specials, £89.99 is still pretty reasonable for peace of mind.

Even the "real" Denso plugs have been known to fall apart in service.
The rotary is not a plug-friendly environment.

That's correct I have seen this first hand a couple of times. My recommendations are:

Naturally Aspirated.
Leading NGK RE7C-L or RE8C-L
Trailing NGK RE9B-T

Forced Induction anything up to 1 bar

Leading NGK BUR9EQP
Trailing NGK RE9B-T

Carl
For us novices could you explain the reasoning for the BUR9EQP choice for forced induction please?
Would thy benefit my car?
Thanks

They were what was fitted to the FD RX-7 - colder plug, less chance of detonation.
The small ground electrode should be near enough the same gap with the centre, however the X shape part of the ground electrode is closer to the centre than on RE8C-L etc, so I would assume that this benefits in a more reliable spark when boost is added.

Just a warning to anyone thinking about slapping in BUR9EQ's into their engine, should you put BUR9EQ's into the trailing these will deform the housings and your "cheap" plugs would now have cost you an engine rebuild. they can be used perfectly fine for the FI engines but in the leading only.

My recommendations still are as below:
