spark plug equivalents

Wig

Haynes book says to use
Bosch FLR8LDCU


They seem to be very expensive, £4 each I need to know some alternatives that are gapped at 1mm and are the equivalent

chunder

NGK would be a good bet,although £4 each is about the normal price most people will pay, other makes are champion(personally wouldnt),motorcraft to name a few they will all be a similar price,would i fit £1 spark plugs definately not!!

skiddlydiddly

I don't really think £4 is expensive for a spark plug considering how long they last.If you find an alternative you can always gap them yourself with a feeler gauge, cost only a pound or 2.

NGK BKR5EK is the equivalent but as it's LPG I might go for the BKR6EK, which is supposed to be better for it.

As to price, I used to buy plugs for 2.50 each not that long ago - about 4 or 5 years.

Prices are going crazy.

However I don't see that they need to be multi-electrode and am still looking for a single electrode alternative. Which should be cheaper.

Single electrode is then going to be

Go for the bosch, they're a better plug.
They're twin electrode, so you can't alter the gap.

They're Bosch, maybe branded Vauxhall on the box, but it's bosch on the plug.

Certainly a better price, pity they don't show shipping prices easily

Mister solutions seems quite cheap

Them GM09 Plugs from Autovaux are cheaper than Vauxhall Trade club... Shame the postage costs are sketchy as said.

Better spark to ignite a weaker mixture. If the manufacturer has specified them, its because there is a reason. A manufacturer will save 0.1p on a component if they can so they're not going to be fitting more expensive plugs just to be nice.

You don't need to replace them every year either.

The spark will jump to the nearest electrode, having 2 electrodes won't make it "better"... it won't devide itself equally between the 2.

The only reason for having multi electrode plugs is for (marginally) longer life.

If you can find suitable single electrodes cheaper then get 'em, they'll work fine!
