NGK heat range "5" translates in most cross reference charts as Bosch heat range "8" and most LPG guides recommend one heat range colder, i.e. "6" in NGK and "7" in Bosch, the numbers going in different directions.

    As I live at the top of a looong ascent from Adelaide via the SE Freeway, my plug recommendations tend to get a workout every day. WR7KI33S seems to be an excellent all round performer in all the low/medium comp V8's and I would only recommend the WR6KI33S in extreme performance conditions.
    Well I tried to order the WR7KI33S tonight, but Bosch only had 2 left in stock, bit useless for a 8 cyl vehicle. The WR7KI33S are double platinum.

    I did manage to order the WR6KI33S which is a plat/ir plug, and was recommended for CNG/LPG in their cat. The price is cheap enough so if they don't last long then so be it.
    But as you say their cat is often wrong.

    I hope they've still got one because I've just sent the faulty one back.

    I just ended up using the most accessible plug & swapping the new ones in until the crook one revealed itself.

    Time for me to replace my plugs soon and these WR7KI33S ones look to be the business

    Seems like everyone is happy with them

    I've been a bit browned off with the difficulty in getting quality Bosch plugs as they seemed to have sent production off to Russia of all places. Not sure how stocks of the LPG plugs are going as I've not sold too many this last year. I've decided to try some BRISK Silver plugs instead, so far so good for the handful of vehicles I've fitted them too including one P38. The two part numbers I've got for the low comp V8 are LR15YS, or DR15YS if you prefer the 16mm hex. The local supplier is just one guy, Robert Morton. Contact via here:

    I stopped selling Bosch plugs due to the constant stock supply problems, in fact a lot of Bosch stuff was always in low stock levels.

    I notice the LR15YS has a 0.9mm gap and the DR15YS has a 0.7mm gap

    Do you gap them after you receive them?

    The plugs with a 0.9mm gap have a suffix -9 after them. Of course I always check the gaps and adjust accordingly. 0.7mm seems to be best.
