Can anybody tell me the spark plug gap for a 2001 3.3 limited grand voyager and if NGK LZTR5AIX-13 spark plugs are better than the factory fit items and if they have the same service life . The voyager is runnng on liquid petroleum gas , I believe this is why the NGK plugs were fitted as the lpg makes the ignition system work harder . Thanks .

 

look under your hood there will be a plackerd with the gap on it.

 

hi , thanks for the fast response. I;ve looked under the hood and the only labels there are are for the ac refridge and towing wieghts . This is a uk supplied car , maybe they don't specify this for the uk.

 

then have no idea

 

Gap is .048 to .054.
