just wanna let it be known that installing these plugs (in my opinion) is a waste of time and money. I first seen them on Horse Power Tv and was skeptical, very skeptical actually. but i read mixed reviews on them but never found anyone to have a real problem with them aside from not getting the promised dramatic increase in fuel economy. So i bought one for the Lawn mower and holy shit it made a difference. lots more torque, its near impossible to bog it down now, (needless to say i dont measure MPG on a push mower) Anyhow the long and short of it is i put 6 in my '03 4.0l and they are the shits. for the 10 min the ran smoothly i noticed NO imporvement from the plugs that had 100,000km on them. then as the truck warmed it got worse and worse until it was evident that one cyl was not firing and i later found that another was barely firing i pulled them all and put in 6 bosch and i couldn't be happier. i put 4 in the girlfriends saturn, better expierence then the ranger in that she got the pep and smoother idle....unfortunatley she was IDILING smoothly at 1500 rpm. pulled them too, back to NGK.
its been my expierence in the lawn mower (and recently snowblower) that in a less complex and hotter running small engine these plugs work great, and i would recommend them, but would never waste money on them for a vehicle again.
i don't know if i bored most of you to sleep or not, but if there is anyone on the fence about it i hope i was some help.
P.S. i did read a few threads here on TRS and MANY ppl said to stick with bosch, cant remember their names but, the are absolutly RIGHT
