A: 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 ...

**Q: Can i buy 6 spark plugs. my lexus gs350 has six(6) cylinders**
A: 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

**Q: can these plus work on 2007 swift**
A: 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.
