41-993 Professional Iridium Spark Plug (Pack of 4)

Good

Ojala volvieran al precio que las compre estaban regaladas

Having read negative reviews where orders were received short, I was worried that something would go wrong with the order. I took a chance as it was sold directly by Amazon and in my experience, if something goes wrong, they will correct it. It was a good price and and I bought 2 packs of 4. They were received complete and all plugs were gapped 0.060 in from the factory as they were supposed to. All was perfect.

Excelentes bujías de iridio, calidad premium de General Motors, vienen grabadas en el metal de la bujía con la leyenda: ensambladas en U.S.A. con partes japonesas. Cada paquete contiene 4 bujías, pedí 3 paquetes para tener 12 bujías en total. Funcionan de maravilla en mi Chevrolet Astro 2003 AWD, motor Vortec 4.3 Son originales, premium y de excelente calidad, las recomiendo ampliamente.

I searched quite a bit for the proper spark plugs for my 1997 Chevrolet Pickup 5.7L V8 and found these to be the very best ones that I could use. Basically the OE spark plugs that GM used originally in the engine, with the iridium upgrade. I could tell right away after firing up the truck and the engine idling that I picked the right ones. It's never run better. I recommend these for a GM 5.7L "Vortec" engine, I believe from 1994 to 1998.
