Hi guys,

Im just wondering if there is a specific spark plug for MV bikes or majority just use any spark plug that works fine with the bike.

If there is a specific one, which is the best ?

Common in the market are the Iradium series from Ngk or Denso.

NGK CR9eix Iridium, Iridiums give higher performance bit do have a shorter life when compared to a double platium plug. Andrea Goggi said not to use the Denso, the combustion chamber does not suit them apparantly

Interesting. I've been using Denso U24ETR for about 10,000km.
Dyno says 120 odd Hp.
Brain says 4 gear wheelstands. :naughty:

A lot of the Italian lads are also using Denso with good results, I'm only repeating what Andrea Goggi said here :)

Just as an aside too chaps, and not trying to go too far off the track here, but Iridium plugs weren't originally designed to produce "bulk easy horsepower" they were developed to last 100,000+ miles for U.S. E.P.A. requirements.

Usually the E.P.A. and the tuner are somewhat at a difference of opinion.

It's strange that you say that, I went to the NEC and spoke to the NGK expert on.......the NGK stand, not about MV's but about my sons TT engined Golf mk2 which is running about as much hp as a std TT will give and 'eats' plugs about every 4000miles, he told me the Iridiums will give the best performance but the double platimums will last longer :)

I would just use the stock plugs set at the correct gap. The amount of power increase, if any, would be quite small in comparison to what the engine puts out now. You'd never notice it.
