changing sparkplugs

[B18C5-EH2]

Stock plug number will be an NGK ZFR5-F11 - and like Batl said, they're under the plug wires.

1. Pull the wires out of the way

2. Grab up a 5/8ths deep well socket and remove the plugs

3. Add a dab on anti seize to the new plugs' threads

4. Start each one by hand and tighten them - don't over tighten them

...and again factory plugs for a B18A/B engine are coppers, which need to be changed every 30,000 miles.

If the car is boosed I'd check and possibly change them every other oil change, depending on if the set-up is tuned and if the engine runs rich. lean, or burns any oil.
