I have a 1997 max, gle trim with 135xxx miles, about time for spark plugs, i know ngk and denso are the only brands i should be using, i heard v power and double platinum were good, but the autozone guy gave me g power plugs instead of the V power plugs. Will these work or are they going to ruin my engine?

 

I installed the G power 40,000 miles ago.
My car runs well.

 

Theyre fine, you'll just want to change them more frequently every 30k or so.

 

+ 1 … and changing them out on Schmelly’s suggested frequency won’t result in anything but good.
