What spark-plugs for 240BHP VX ?

[Marius]

I´m currently using the Champion CQC57C which work fine when engine warm and letting the car fly on road & track. However cold-starting and pottling around slow roads seem to be an absolute killer for those plugs, getting soakin´ wet. Maybe grade 5 is too cold, what do you think ?

 

Alex, Arnie, Dave, what plugs do you use ? NGK ?

I use NGK plugs (I dislike Champion)

BCR8ES for sprints and track work

BCPR7ES for road use.

Yhe 8's seem to foul if the engine is idling for long in traffic etc.

The engine starts on the button with either plugs fitted.

Marius,

 

The Champions suck. I used to use the warmer C59C (when I was running around 250bhp) and even they always used to foul up when cold on my car, often before the engine even started!

 

NGK racing do a plug type NGK R5686-9 - expensive at £18 each retail, but they hardly ever foul up. These are the best option IMHO.

 

Splitfire 393C's are also OK at £25 /set if cost is an issue!

I tried champions and they really were not good. Lots more misfires.

 

I use BCR8ES NGK's.
