Spark plug gap
I repalced 4 out of 6 spark plugs last weekend and noticed the old ones had a large gap, approximately double that of the new plugs.
The new ones are Bosch platinum Will a larger gap increase performance and fuel economy? I appears that the mileage is a little bit less than before. yeah, I know, there are 2 more plugs hidden somewhere that need to changed as well

Re: Spark plug gap
.048-.053 is the recommended gap (some come in the package gapped at .035). I hope you are happy with the BOSCH Plugs, most of us use the OEM Champion Double Platinum good for 100,000 miles.

Re: Spark plug gap
Plus Bosch plugs are junk,they do not last and the Champions do last.I see Bosch plugs and there is one place they go: in the garbage can!

Re: Spark plug gap
It's normal for the gap to increase as the plug wears. No, a wider gap will decrease mileage and perfromance. A wider gap equals greater resistance to the current that has to cross that gap to produce a spark.

Re: Spark plug gap
thanks for the replies, I guess I'll switch to Champions then.
I thought I read once in a Hot Rod magazine long time ago, that a larger gap combined with a powerful coil (MSD) would produce a better combustion, therefore better mileage and performance. Of course that was meant for carburated V8 engines with distributors  cheers
