You've done this roy? if there's room for the bolt to back out. there's gonna be room for the swivel with 12" extension-

if this is a tricky one do recommend you spend the extra scratch for a swivel socket (1/2" drive or 3/8" or even 1/4" if starved for real estate), sturdy enough) to get into inconvenient angles-

a lot of sparkplug sockets have a hex top so you can wrench 'em if in a tight space....refuse to believe that a intake manifold need to be removed to get at the sparkplug....whooof- luck on that one.


i am an technician and i own an montero sport 1999 and yes i've done it before many times

You Need to remove the intake plenum/manifold and coil pack....I suggest taking pictures of the removal at many stages for reinstall assist...also be very careful to MARK ALL of your vacuum wiring harness connections and check for cracked hoses and broken wires...(note DO NOT remove injectors or fuel rails) also if plugs have been ignored for longer than 60k between replace check coil pack for burned or leaking issues, as plug gap loses integrity it takes more spark to ignite fuel and thus makes coil pack heat up and often times not cheap it out on plugs they are hard to get to and need to be pre-set platinum quality...NGK platinum fine wire or Bosch platinum plus 4 are what I not try to adjust gap as they are pre set....take your time with this....I know it is hard to believe that you need to remove intake plenum/manifold but that is how its done!!! Remember engineers design these thing to run not necessarily for ease of repair...Service technician job security...???? Good Luck, Gary
