Another reason not to use Bosch spark plugs in Japanese engines!!

[fueler]

I've advised against these ever since I had failures in both my Honda and my QX4. The newest story from a fellow R50 Pathfinder owner:

Quote »We got to the fouth plug cyl.2 and while trying to take the old plug out, the plug broke! Not just the porcelain, but the threads sheared from the nut!

It's the plug with the nut and porcelain and if you look into the head, you can see the inside of the treads and the prongs from the plug (they were bosch +4 garbage)[/quote]http://www.4x4parts.com/ubbthr...&vc=1 anybody considering brands.... use ngk!!

when i bought my pathfinder it had 123,000 on it.the first thing i did was a tune up.ngk plug and boy were they tight.but none broke.look at the gap in the plug and it still ran good.i agree with fueler i wouldnt put anything in but a ngk.
