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.

Great quality, received fast, easy to install on my 20112 Ford

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.

Great product I always use Bosch products for me Jeep

Love these platinum plugs . . an upgrade over the older model Bosch platinum plugs I took off. The old plugs idled fine but protested under load. These newer version plugs cured that instantly. Don't recall when I installed the original set - that is a problem with these platinum plugs they last four years. Opened up one spark plug box and put the date on it and stuck it in the glove box. Also I cleaned the treads with a thread chaser and applied anti seize to each plug. Didn't apply any dielectric grease to the spark plug boots but should have, here in the desert have had no issues with spark arching.

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.
