What is the spark plug gap for a 04 1.6 toyota avensis


Great that you are checking/measuring the spark plug gap...many people overlook this setting...you can not count on the new plug having the correct gap...Most plugs with today's electronic ignitions use the 35 mm gap...however, your best answer is to ask your Auto Parts store what the gap should be when you purchase the new plugs...Good job, hope this helps.

What is the proper spark plug gap on 04 Chevy malibu ? Is it .060 ? Is that not to big ?


If you have the 3.5 liter engine, that is the correct gap. If you have the 2.2 liter engine the proper gap is .042. Hope this helps...

What is the gap setting for the spark plugs a 2004 trailblazer?


I have been told by mechanics and 2 auto stores that the gap should be .043. I don't know where people are getting .060. but my plugs are .043 and my trailblazer does not misfire or run poorly. Also, check the gap always, even if it's pre gapped because the handling of spark plugs could cause a change in gap. IE the plug bouncing in the box, vibration, etc.
