Spark Plugs And Lpg.

[randyreindeer]

Is the standard plug gap ok for use with LPG? Mine are due a change now and I know the Gap is quite large anyway. I have always had to regap on other LPG set ups but they were all basic carb set ups.

Hi mine is running fine on the original plugs & gap its a brc plug & drive multipoint system, I have been told its better to run on standard ngk plugs rather than iridium though. i still have iridium in mine though.

Hi

It is platinum plugs that don't like LPG, although this varies car to car and plug to plug, use the standard gap, you only had to increase it on older cars with a standard ignition set up to try and get a physically bigger spark to ignite the LPG's dry mixture.

iridium are fine and I've never seen a Lexus with problems on LPG if it is serviced on time etc....
