does it need gapping or ther is no need to gap this plug?

There is no need to gap this plug. It comes pre gapped. If you attempt to try and gap this plug or any iridium plug you will break the center electrode and render the plug useless.

Will this fit 2016 toyota prius two hybrid?

I have no idea if they will work however if they fit and meet the heat range I would think yes..I have put them in my Lincoln LS 3.9L V8 three or four years ago like 60,000 miles ago.. yes worth the money ...

Can i buy 6 spark plugs. my lexus gs350 has six(6) cylinders

this item is for 4 spark plugs only please see other items for sale at Spark Auto Shop for the correct product quantity for your car

can these plus work on 2007 swift

They might could work but don't buy it from this dealer. Bought 4 in the summer for a toyota and they didn't work. Seller didn't even address one of my emails. Worst service ever.

Installed these as recommended by a mechanic friend of mine for a Chevy prizm. I have not noticed any real benefit after 7 days, yet they came early and pre gapped, easily installed. Only time will tell. They were recommended for longevity and reliability.
