i use normal ngk spark plugs heat range 8 and goes fine with me and hold up good in boost about 18 to 20 psi

I doubt you would have much to gain over using standard iridiums.

We sell Denso Racing plugs but they are so expensive, up to £20 per plug.

the racing plugs are very good, the cossie boys fit them,

although i must admit they arent worth it unless you are racing every weekend.

a set of 4 is about £100,

i dont think there would be any gains, i think they just last a lot longer in extreme conditions,

i might give them a go

yeah they are expesive than iriduims.

ill find cheaper racing plugs.

if there proper racing plugs then they wont be cheap.


champion are ok, but in recent years qaulity has gone downhill massively, there not as big as they used to be,

still worth considering though
