Spark Plugs

[tom_burnley]

Hi all....

Changed the spark plugs last week to the champion ones from eliseparts.....talking to Dad last night and he says that 'in his day' you used to have to set the gap by using some tool or other, and a hammer

is this the case - should I have done this before fitting them - whats the storey there then - I though tI could just screw 'em in. Tell me I did good, or else I worry.

Yep - gapping spark plugs used to be the norm (well before my day). Using a set of engineers thicknesses/feeler gauges to make the correct gap for the car.

I suspect they're all standard gaps now or there are different models of spark plug for different cars (a bit like wiper blades).

If it's running OK then they're fine.

for an elise s2 the plug gap should be 1mm + or - 0.5mm
the s1 for some reason is 0.9mm + or minus 0.1mm according to the workshop manual

Your dad is still living in the days of weedy coil ignition systems and spark plugs made of tin - since everything went electric and platinum it's no longer super criticial, whatever they came as will almost certainly work fine.

Worth checking, at least by eye, next time tho.
