WHat do u gurus recommend?

Rice Rocket

PFR7B made by NGK

Grant

Aint a guru more of a muppet

I use these as advised by Bob Rawle on my modded MY02 :)

I bought them online at http://www.spark-plugs.co.uk/ but I hear that Alyn at asperformance.com has them on the shelf !

Midlife.....

And they should be replaced every 10k miles or less.

thanks guys
