The scheduled maintenance calls for the spark plugs to be changed at 100,000 miles, and I'm at 115,000 right now so it's over due.


The owner's manual has the type of plug to buy, AGSF 34FP. I got those, kinda pricey but only have to change every 100,000 so I guess it's ok.


The owners manual sez to check the emissions tag in the engine compartment for the correct gap. The sticker sez .062 - 0.68 but doesn't give any units.


Is that metric or inches.


The plugs look set to 0.0625 inches.

 

that's in inches.

 

Thousandths of an inch. Sounds like they're good to go.

 

Actually, it is stated in inches. If it were in thousandths, it would have been stated as 62-68.
