Hey everyone! Nearing 67k now and I think it's time for my first sparkplug replacement! I have seen a decent tutorial on their replacement and with the removal of the air duct it doesn't seem too terrible.

I am now deciding between the Bosch and NGK options for sparkplugs and would like some input. Also, what gap should I be setting these too for my stock engine? Finally, anything little or annoying to watch out for when I do it? Thanks all!

Only comment I have is the gap on the NGK is definitely not right for our engine. .026 - .028 is the preferred range.

I set mine at 28, but I think it would do better at 26 27 tops.

I thought there was some threads early on about other than Motorcraft plugs not necessarily being happy in our engines.
I'll let others comment, as I've only used the stock type plugs so far.

I'm not a fan of NGK, I'd stick with Motorcraft plugs, and make sure you gap them. Can't tell you how many times I put plugs in something at work, plugs show up and you find one that looks like they dropped it off a 100 story building. Ground strap is smashed right down to the electrode.
