Best spark plugs for mr2 turbo

[Leon.]

BKR7e from spark-plugs.co.uk are under a tenner. Swap them out every 5000 miles or so with the oil and you'll never have to worry about a weak spark or bits of platinum falling into your engine.

Jon, I thought the problem of spark plugs falling apart was related to iridium plugs?

Am I wrong on this one?

I thought iridium was ok and platinum fell apart, perhaps someone can clear things up for us

[jmachling]

It was the iridium tipped plugs that I'd heard could fall apart - the tips are really fine and look delicate.

However, is this another urban myth that we're perpetuating? Would NGK really produce a plug that could fall apart and do expensive damage?

I guess they could get damaged by excessive detonation, but the cause of that should probably be more of a worry than the plugs I think.

Jon, excuse the gloating but this is one of very few I'll probably have over you so





P.S. I had heard from Rogue that this has actually happened. Was a very long time ago I had the conversation so could be wrong....

Sorry for the necro post but….

I'm cleaning up a 1993 turbo (hopefully for some shows) and it has NGK R BKR5EQUB plugs (well, it has three of those and one NGK R BKR6EK??)

Why would the bkr5equb's have been used?

Are they any good?

Off the Halfords shelf copper plugs.

Not bad, not the best. I'd recommend running 4 identical plugs though.

^ Fair enough, thanks for that. I hadn't seen plugs with the four parts on the end before, thought they may have been something special.
