Spark Plug help

I use Bosch Double Platinum with good results, both in economy and power.

I believe the Split fire to be a gimmic. Bosch are generally considered great plugs and platinum is good but I've had several experts tell that NGK's work best in this (and most) Japanese engines.

Why would you be changing 'nearly new' plugs anyway?

Problem?

Extra cash?

Send it to me!

If your Miata has the original plug wires, be sure to replace them. When the wires fail, the result can be a damaged coil pack, O2 sensor, and cat converter.

LOL wish it was spare cash. But I get the feeling that the plugs are not as new as he said they were and lets face it it's cheap insurance. :)

The plug wires are blue and look to be in good shape and I seem to remember that on the 92 the oem wires were black so I am assumeing they are newer,but, as with the plugs they are a bit of cheap insurance.

i had nothing but bad luck with bosh platinum in my nissan v6. i didn't want to believe they sucked so bad, and i replaced a lot of other ignition parts trying to cure misfires under load. then i replaced the plugs with the same (surely two sets wouldn't both suck). then i put in plain ole' ngk copper and the truck ran better than it ever had.

my '99 sport gets nothing but ngk copper extended reach (on magnecore wires), and runs beautifully.

fwiw,
