If they're denso/hks id inadvise, electrode tips have been known to break off and kill said engine.

Ngk on the otherhand have been superb, car fires up fine every morning, can be a bit grumpy when cold but that just tends to be a scoob trait anyway but once warmed she flies along.

Sorry to hijack but im thinking of fitting some ngk iridium plusg as the ngk pfr7b's i have now gapped to 0.7mm are causing a missfire at 1.5+ bar boost,they just seem a bit pricey at £25 per plug.

These are typically what you'd run on a classic sti and ran fine when mine was a standard wrx, as you can see by chasing the exact type you get much better prices.

hth

eBay.co.uk - BKR7EIX items at low prices

Those plugs work on all models iirc.

Beeston Motor Spares in Leeds (Well, Beeston really...) sells them for £34 for four if you are anywhere near them it's worth a trip down
