Which Sparkplugs to use in 1999 Civic LX?

My 1999 Civic LX has reached 100,000km's so I believe that it's time
to replace the plugs and wires. I'm going to be replacing the OEM
wires with blue NGK's but which sparkplugs should I use?

Also, what is the appropriate sparkplug gap for this car?

 

====================

If the car still has the original hood, the info you seek is on the
sticker. It's also in the fine owner's manual.

I've always liked NGK's plugs for Hondas. In fact, they're spec'd as OEM in
addition to ND's. If I remember correctly, NGK laser gaps their plugs at
the factory. I've never found one that was off but it couldn't hurt to
check.

OEM is NGK, and they seem to work not-to-bad...

 

any one who uses champion plugs in a honda is an idiot
only use ngk's, there the best for the car

 

I use NGK, regular copper - it's better to adjust spark plug gap every few
years, so might as well replace the plugs - this no need to buy platinum for
that.
Bosch works well too, just be careful to gap it a bit more than recommended
(around .050 instead of .039-0.043).
I've been told by a mechanic that otherwise you might have misfires & bad
fuel economy (this is only for the Bosch plugs), since they're not
specifically designed for Hondas.

To be on the safe side, go with NGK - be sure to torque them to 13-15
feet-pnds, and use some lock-ease compound on the threads.

 

OEM is also Denso and thats what I have used. Owners manual on my
1999 Ex says Denso or NGK and Auto Zone had the Denso. They were
already gapped to .04 just like the manual said. I don't have a
torque wrench just tightened like it said on the box. My mpg jumped
about 2-3 mpg. Wires looked good..

Hi,
I'd put in a set of NGK Platinum ones and forget about them for a long time.
