For a Legacy turbo 93. Would like to find out more.... How much new /secondhand??? How to test??? How to tell if going>?? anuy cheap fixes!!

Where are they on the car??

 

2 each, bolted either side of the engine. Held in place by 12mm bolt. Undo bolt then pull they should just pop off the plug. 2-pin connector secures to wiring loom.

C&K sell them for about £43 + vat and delivery, so work out at just over £200 a set.

Don't bother with 2nd hand, I bought a set from a well known Subaru breakers and they where in worse condition than my origionals (got a refund tho')

Symptons include hesitation on light throttle when cold, occasional misfire and large misfires at high revs....

I've been thinking of getting a set for ages, but can't bring myself to part with £200 for what on the average car would normally be a £20 set of HT leads.
