Currently have HKS plugs and I think I've had them in for approx. 10K miles/ 12 months. Noticed that the car has started to hesitate and miss when changing gear. Last time it did this I changed the plugs and it seemed to cure it.

Excuse my ignorance but could it be anything else and are there any better plugs available rather than spending £75.00 on HKS items.

Take the plugs out and re-gap them
It'll give you a chance to se if they are damaged too.

If it does turn out to be the plugs [again], why not simply go back to original fit NGK's they are virtually guaranteed to do at least 30k and I've never seen a problem with them.

Stnadard NGK's PF6RB are good...............

NGK Plugs. 6's are recommended by Subaru but many people with tuned engines run PFR7Bs to good effect.

I tried putting champion plugs in mine, ran like a sack of s><?. Brought some NGK's runs and idles fine, go for the NKGs. You can order them from www.sparkplugs.co.uk

I have used PFR7Bs for years and never had any problems. The colder range plug will help reduce combustion chamber temperature and help put of the onset of detonation.

I bought a new set of PFR7B's from Town End Garage last week. They cost me just under 40 quid all in and arrived recorded delivery the next morning, and I had ordered them mid to late afternoon. Very impressive service, and I haven't seen them cheaper anywhere. Thanks Stuart.
