Hi,
Unfortunately, there is no easy way - the upper intake (surge tank) has to come off in order to access the plug wires and plugs.
Removal
1. Detach the P.C.V. hose and brake booster vacuum hose.
2. Disconnect the connecting part of vacuum hose.
3. Remove the surge tank stay.
4. After reducing the pressure of fuel pipe line to prevent fuel overflow, disconnect the connecting part of the high pressure hose.
5. Remove the surge tank stay.
Once this is off, then remove ignition coils and spark plug wires. At that point, you can access and remove the spark plugs:
REMOVAL AND INSTALLATION OF SPARK PLUG CABLE
Improper arrangement of spark plug cables will induce flashover between the cables, causing misfiring and surging at acceleration in high-speed operations.
Disconnect the spark plug cable from the spark plug. Pull on the spark plug cable boot when removing the spark plug cable, not the cable, as it may be damaged.
2. Using the spark plug wrench, remove all of the spark plugs from the cylinder head.Take care not to allow contaminants to enter through the spark plug holes.
3. Check spark plugs for the following:
(1) Broken insulator
(2) Worn electrode
(3) Carbon deposits
(4) Damaged or broken gasket
(5) Condition of the porcelain insulator at the tip of the spark plug
4. Check the spark plug gap using a wire gap gauge, and adjust if necessary.
Standard valueSpark plug gap : 1.0 - 1.1 mm (0.039 - 0.043 in.)
5. Re-insert the spark plug and tighten to the specified torque. If it is overtorqued, damage to the threaded portion of cylinder head may result.
Tightening torqueSpark plug : 20 - 30 N·m (200 - 300 kg·cm, 15-22 lb·ft)
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

REMOVAL OF THE PLUGS:
Do not attempt any maintenance on spark plug if engine is hot.
1. Disconnect negative battery terminal.
2. Carefully remove high-tension leads.
3. Use compressed air to blow any dirt or debris from around spark plug hole.
4. Check that spark plug fits squarely in spark plug socket and remove spark plug.
Raise a vehicle and install SST(OK552 131 001) in order to replace cylinder 2, 4, 6 spark plug.
INSTALLATION:
1. Install spark plug into cylinder head.
Tightening torque : 18~22lb-ft (25~30N·m, 2.5~3.0kg-m)
2. Reconnect high-tension leads.
3. Reconnect negative battery cable.
Hope this helps and simple to understand. Good luck
