pull the plug wires out one at a time as you do pull the spark plugs and replace the plug and wires then on to the next wire

what engine? 1.5 liter typically found in the dx and vx the wires are right in the middle of the valve cover (black aluminum plate on the top of the engine will say sohc Honda in white letters) pull the plugs keep track of what hole they go in use a plug socket and an extension on your socket wrench and remove the old plugs, make sure your gap is the same on the new plugs and insert with the same wrench tighten it a quarter turn past snug. your Honda has an aluminum head so you will damage it if you over tighten be careful. once this process is repeated 4 times return the wires to their respective plug and drive.

I happen to have the factory service manual ill upload pictures in a few minutes hold on.Sorry but there is no information on removing the plugs themselves but I can tell you that the gap is 1.1mm D15B8/D15Z1ZFR4F-11 (NGK BRAND) KJ14CR-L11 (Nippon Denso Brand) - Normal Driving Conditions 5F 16CR - Hot Climate or RacingD15B7ZFR5F-11 (NGK BRAND) KJ16CR-L11 (Nippon Denso Brand) - Normal Driving Condition 6F 20CR - Hot/RacingD16Z6ZFR5J-11 (NGK BRAND) KJ16CR-L11 (Nippon Denso Brand) - Normal Driving Condition 6J 20CR - Hot/RacingTighten the plugs finger tight then torque to 18N*m (1.8kg-m, 13lb-ft) (the best way to describe this if you don't have a torque wrench is moderately tight, don't put your whole body into it but make sure its snugged pretty good)*** NOTE: Apply anti-seize compound to the plug threads before installing ***If your engine is a B-Series your out of luck on plug number recommendations but everything else should be the sameon top of the head there are 4 little holes with wires going into them, remove these wires then use a socket and a ratchet with a Spark Plug socket (not the same as a regular socket of the same size, but if you only have a regular deep socket then be careful to keep it at a flat angle, if you let it tilt while tightening or loosening you can break the porcelean of the plugs making them trash and possibly making a big mess where its hard to clean up)
