Nice
Arrived decently quick, came packaged with another product that I had issues with (it was water bottles and they spilled) but thankfully the spark plugs were not damaged at all! Already put them into the car and they fit great! No complaints!

Delivered in excellent condition, but arrived very late, fits and works well with my hummer h3 2008

Misfires due to older plugs, definitely needed replaced and cleaning them didn't work.
Always the first suspect when you have a misfiring cylinder.
