Don't liek to rain on your parade, but LPG plugs border snake-oil. Brisk brand should be positively avoided.
LPG likes a narrower gap, and that's about it. Nothing wrong with LPG plugs, per se, but your money can be better spent. Use quality simple plugs. £10 a set on eBay, I shouldn't but I squeeze 30,000+ out them. You might be better to not follow me, and do only half that. They are fine to 35K, but I reckon harder on the already tired 250K coil-packs. I've had a four CPs in the same mileage. Started and ran fine, but I'm sure my tired 35K plugs were not helping.
The object of the LPG exercise is save money, so save it. Pay £2.00 each delivered. Denso K20PR-U 0.7mm
