Spark plugs - NGK question...

Post Thu Feb 12, 2015 12:46 pm

Looking to buy some NGK BPR6ES spark plugs and I've noticed, (especially on ebay), that there seem to be a lot of people selling these with another four digit code on the end!!!

I found an ebay listing stating 'for BMW E30' selling NGK BPR6ES 7822.

Can anyone confirm that is what I want???
(For my M20 2.7)

I dont have the boxes from the previous ones I bought and there appear to be a few other options, like BPR6ES 4824 / 7131....
Anyone know the difference??? Different thread maybe???
The 7822 does seem the most common at least!!!

Won't the number be on the old plug ?

If I get a chance I will take a look at the NGKs sat on the bench at home later.

the 4 digit code is the ngk short code, BPR6ES (long code) 7822(short code)

BPR6ES is the alternative plug listed for the early hc m20b25, the recommended plug according to ngk is BPR6E (6464)

Cool, so 7822's should be all good then!!!

No idea if the part no. is on the plug itself - I assume it should be!!!
Bit of a problem with time to deal with it to be honest and my tools are quite well buried at present!!!

Was recommended the BPR6ES by Ant when he built my engine, so I've always stuck to it - just don't remember seeing a 4 digit code last time I bought some!!!
