The correct spark plug gap is 0.052 inch. Try to look for spark plug brands that fit the Mazda M.P.V. engine and already has the factory gap set near to this correct setting.
1-4-2-5-3-6
0.55 gap (+/-0.04; which I implore you to try to gauge on a disk gap tool...)

Owning an MPV myself you have have 1 of three reasons. 1. bad spark plugs, 2. worn distributor cap and or rotor, 3. faulty O2 sensors. And some of the very simple things like a vacuum hose off somewhere, spark plug wire off. Good luck. Type your answer here...
MPVclub.com has a somewhat detailed description on how to do it. If you remove the plastic you will expose three of the six. Then you have to remove the plenum/manifold. Check out the details on the website. Hope this helps.
