Plugs

[Room42]

Anyone used these? http://www.bosch.com.au/content/language1/html/5684.htm I have 8 of them and I'm due for some plugs. Dont tell me about the cheapies, I already know

Try them and ley us know how they go and hoe long they last

I'll chuck em in before the weekend and try them out. They'll last a long time because of the materials used. Only thing I'm concerned about is that they'll be too hot. The number on them is HGR8DQ1.

I got Denso Iridium plugs with 160,000 km service length, gapped at 0.9. The gap was well over 2mm within a year and 20,000ks and starting to break down. Perhaps its the ethanol and high boost but I wouldn't believe the marketing hype too much... That said, they look good, I wouldn't mind giving them a go myself.

I put them in and the car goes like normal. No extra knock so I guess its all good. I haven't driven it much since so I'll go for a good strap this weekend and see how it goes.

Well the car started missing under boost and it turns out that the plug gaps were too big. Almost 1.5 mm. There are 4 prongers per plug so I swapped out for some cheapies at 0.8 mm and hey presto no more miss. There are marks on the coils where they were arcing to the coil mounting brackets. I couldnt be stuffed trying to adjust 24 prongers cos of the way the plug is made it would be a bit of a guess anyway. As far as performance goes there is no difference between the $20 plug and the $4 plug.
