sparkplug question
Hi guys I know this has also been tossed around much like the oil thread but looking for a little guidance.
I Have a 1973 911T with a 2.4 stock engine with a zenith tin 40 carb. I live in Ontario Canada and only drive in the summer months and no track just back roads on a sunny Sunday. Car currently has NGK BP5ES plugs and I have them Gapped at 0.7 which I got out of Wayne s motor building book on page 203 under ignition timing although the plug listed is a W230T30 and I'm not sure what make that is. Anyway just looking for an opinion as to whether that plug is to hot for my engine and is that the wrong gap. Thanks in advance. Mike |

Hi Mike W230T30 is a Bosch spark plug number and it corresponds to the NGK plug you are using. So, if that is what Wayne recommended and the cross reference chart I used is correct, you should be good to go. No problems with fouling or electrode burning? If not, the heat range should be OK Not familiar what the correct gap is for a 2.4 but you should be close at .7 mm

Yes you are fine or the BP6ES a bit cooler. Your gap of .7 or .8 is good, I believe they come gapped at .030 in. which is what I use on the 6's.

Thanks Dave I thought that was a Bosch plug but tried to Google search it and could not find it.
I'm just about to put new plugs in and wanted to make sure they were the Write ones. And by the way Brighton had there Apple fest this past weekend which I missed but I guess they had about 300 cars in the vintage car Show. |

Thanks for the reply 911s55 and so if I decide to try a little cooler plug and go with
The BP6ES then i should just go with the gap they come with? Thanks Mike |

Just run a gauge through them but all those I've used are pre gapped.

I agree, always, always, always check the gap of new plugs before you install them. One of the oldest mechanics rules.

Has the world gone mad? French spark plugs ? really ? I just pulled out my dealer installed plugs to check them after four thousand miles. The damn things are made in France. Beru 14R-7DU. Went back and checked the invoice from the dealer and they just list a porsche spark plug part number. unbelievable
