Spark plugs

Anyone like to recommend the best choice? Obviously Ive got sets of standard NGK BP6 type plugs (I appear to have BP6ES while stockists recommend BP6EH).
The latest trend of Iridium plugs seem to come with big claims and my local gargae friend stocks Denso plugs and can get me a 4 pronged effort....but is any of it worth it??!

NGK s everytime for me- always found they have been good in road cars including saab turbo v8 landrover quick midget with a 1430 motor, and a 2.3 chevette on twin 48s. they also saved me having to have two sets of champion plugs in the race car one to warm up with and one for the event.
also seem to be good in the estelle with a warm 136 engine

My post was more aimed at whether it was worth buying the newer style of 4 prong or Iridium plugs?

I always presumed that the multipronged tips were a long lasting high mileage feature rather than performance, so the plugs could stay in longer.

You only fire one spark, and if one of the tips gets contaminated, fouled, or whatever, theres still 3 more to choose from.

Id just run NGK plugs, but go up a number for a slightly colder plug. I run BP7's in my Rapid, with the taper seat because they are cheapest.....

I don know from racing bikes, NGK do different versions of the same plug. I used to run "racing" plugs in my bikes that had a very fine eiridium lectrode, for a better burn apparently, the downside being that the plugs could never be cleaned or reset properly.

So youre recommending??!

Tight arse yorkshire man and that....

To be fair, a hot Skoda lump is only going to be mild in the general scheme of things, ie compared to a bike engine thats got to spin to 16000 rpm etc.

those 4 pronged plugs are basically just to "extend" the life for the sort of cars that use wasted spark ignition,,,a fairly useless thing to try considering it only has one center core to erode compared to 4 outer ones (the spark will only fire to whichever prong is closest to the center electrode)

those iridium plugs have a following among the sorts that are producing 200bhp+ per litre for reliability under high boost/temperature conditions so i hear from the japanese performance car crowd

i'd say stick with the stock plugs of whatever make untill (which is unlikely) the level of tuning starts overheating them then consider a grade cooler

Just for you Peter, I have gone outside (in the rain) and removed a plug.

Its a NGK BP7EFS......

Your welcome...

Thanks Kieran....I will never call you a lazy dog again!

Its usually not a good idea to play around with heat grades, however some Skoda models ran 6 and some ran 7, so it's reasonably acceptable. The Iridium aren't really necessary in this age of engine.
If you do go to multi-prong plugs, not all have 4, some have two or three, and NGK/Champion are good whereas Bosch: not so much.

I'd recommend Brisk plugs. Brisk is former PAL firm which produced plugs specially for old Skodas.

I use NGK Iridium BKR7EIX spark plugs in Kermit and I've had no problems with them. They're the single electrode type.

Those are the ultimate....but they also cost! I will see what the pennies look like and if I have a night in I will buy them (plugs or beer????)
