What plugs do you use? Also what would be a good spark plug for a car aroung 330bhp?

Any help would be great many thanks steve.

 

Im running NGK BKR8EIX irriduim plugs running 355bhp, there fine. Used to use champion c59c but had too many problems with them.

 

nothing wrong with standard ford plugs mate and at 7 quid a set cant be grumbled at

 

second that.the standard ones are good enough and as said for the price well worth it.

 

Motorcraft 071's (Standard) for me and can vouch they are ok with the power you have.

When I bought my saff it was running 071's and it was sound

Now running denso irridiums and there is no noticable difference so I'd go for the 7 quid jobbies

 

Found the 071's wear out faster / needed changing more often then the denso's.

 

I have a set of ngk iridium plugs in mine there been in nearly 5 years. I was thinkin about getting a set of the ford plugs cause there cheap and a lot of people rate them.

 

Nowt wrong with the 071, they are a tough plug, but IF mapped and running perfectly fuelling wise you will get better running with iridiums, I noticed a big difference when switching to a group a coil and iridiums, much crisper feeling engine, more eagerness low down, smoother idle, smoother elsewhere as well.
