Another Spark plug question...

[bluenose]

Right, i've had a search through and im unsure as to which ones would be best. So far i've come up with these:

NGK - BKR6EK
NGK Iridium - BKR6EIX
Champion - RC7BMC
Bosch Super 4 - FR56

Dont know if it makes too much difference but i dont want some that people have had bad experience with. I've also seen some Denso Iridium ones but they are more expensive than the others.
What would you recommend?

[seanofnp]

[nyk]

I use Bosch FR6DC + 13 from Gsf.
Works out just over £5 for 4 and there single electrode too which is a bonus.

[schakal]

little off topic but always wondered why manufacturers
came up with multi electrode plugs if they are no use any car

or are there certain engines these plugs work wonders ??

[MAXIBOY]

no they are only used to help to increase service intervals. they still only use one electrode at a time but as one where,s out they can switch.

but this also means that very few people check or gap plugs anymore so miss all the information on how there engines running that this used to provide

Go for the NGK iridium jobbies, grade 6 heat range (standard). Iridium last longer and require less voltage to produce a spark, as the tip is 0.6mm - quite a bit smaller than standard.

Don't bother with the ones from GSF as they are double strap type, which is a stupid design as it can get in the way of airflow/efficient burn.

BKR6EIX is the part number for the iridium ones. If you must go standard then the part number is BKR6EK.

Not too fussed about standardsville. Just want whats best all round for the engine with the uprated leads from the other thread. Cheers for the replies lads and lasses! Much appreciated!
