Spark Plugs : which ones to use 4age ?

[jondee86]

SutteR... If you already have the plugs in the engine, try this. Find a
long, straight, deserted piece of road, without crossroads, where you can
safely experiment. An uphill slope would be even better. Stop your car,
and when it is safe to do so, take off like your ass was on fire

Give it full throttle and redline every gear !!! If you can make it to the
top end of 5th gear (say 6000 rpm plus) without feeling the car misfiring,
then your plugs are fine If you feel it starting to miss as you rev out
in 3rd, 4th or 5th, then your ignition system can't handle the 1.1 gap
under heavy load.

If it does miss, try a fresh set of NGK basic copper plugs at the 0.8 gap
and see if the problem goes away. If it doesn't, you need to look at your
plug caps, leads, distributor cap, rotor and coil. These should be clean,
tight fitting, no cracks or broken connectors, and the edges of the rotor
should be clean and sharp. Do the basics first
