I'm on IK31's, but 071's can be used around £10 delivered for a set of 4.

I use 071's in mine at 380bhp, seem to work fine.

Tried a set of IK31's a while ago and must admit tick over was smoother and car seemed more responsive but they only lasted 3 months.

IK31's are too cold as an everyday plug especially during winter time.

Allthough there are excepetions to the rule I usually use IK27's in sub 380bhp, and IK31's for over this power level. However I usually advise something like a Ford 091C if you're just pottering to work and back in winter, regardless of bhp!
