BOSCH 6717 OE Fine Wire Platinum Spark Plug - Single

Almost didn't buy them because some reviews stated they were a fake brand and, also, some reported they broke after just a few miles. Well, there's no doubt the ones I received are indeed Bosch brand. Secondly, after installing them on my 2001 Jeep Cherokee, following correct practicing, I haven't experienced any issues. What I did noticed after installing them is less engine vibration and no power hesitation when stepping on the gas pedal. They worked, the price is right and I recommend them.

I have a 2006 Jeep Wrangler TJ 4.0L . I did notice a smoother idle after a few minutes and took it for a test drive. I can't say whether or not I'm getting better MPG. Will try and edit review later if I notice any improvements.

Works great in a 2004 Jeep Grand Cherokee.

Great plugs for the price! 2002 Jeep Wrangler.

They have worked fine for our 2003 Jeep Wrangler. Just replaced our first set that replaced our Champion traditional plugs and they did a good job as a replacement.
