Hi,

I've got the 4.6L Triton engine and wanting to change out the spark plugs, but after reading and searching I'm a little worried. I called a shop and they want 266.00 to change them. Are they that hard to change out? Can I do them? I'm a little worried after all the horror stories I've read. Does the 4.6 have regular plugs? or those longer ones?

Thanks,

Rick

don't stress yourself out, this generation doesn't have any real issues with the spark plugs. just take your time and make sure you have a nice selection of extensions and a swivel adapter. cylinders 4 and 8 are the worst to change.

It is the 3 valve 4.6 That has the issue.

Yea no problems, -first time plan a half a day to do yourself. With a little research and know-how, you can do a better job yourself. However, the price of $266 is a great price to have it done on that model. $350 is average.

BUT, make absolutely sure you or they use Motorcraft plugs. If your into exemplary maintenance, there's some tricks, preventative measures you can take and certain things you can do and check along the way.

Is there a 4.6L with 3-valves and plug issues? I always thought the 4.6L engines were fine, and it was only the 5.4L engines that had the plug issues ...

I changed my 4.6L plugs with no problem. I took my time and did the job over two days because I started late the first day. It's not easy to get to the back plugs but I did it. Patience is the key here ... and having the right tools before you start. I bought a swivel and a set of wobble extensions before I got started, and I could not have done it without them.

It's nice to wear a pair of thin polyurethane stretch gloves too (PUG 17's are my favorite: ). They give a really good grip, they keep your hands clean, and most of all they protect your hands when you have no choice but to jam them into tight spaces.

You should probably use Motorcraft plugs. I would have -- if I hadn't bought NGK's before I learned about the Motorcraft recommendation. Fortunately my NGK's are great so far. My truck has never run smoother! But if they ever give me any problems I'll use Motorcraft the next time.

Thank you for the recommendation... for the price these sound like they're worth a try. I've always stuck with latex and always been unimpressed.

So basically they are regular plugs and just take my time. So do I still need the anti seize or dielectric grease?

I put a little bit of anti-seize on mine, and plenty of dielectric grease.

just like everyone else suggests ...take your time & things should go pretty smooth.. plugs are your choice motorcraft are excellent...personally I put in Autolite Iridiums/platinums in all my trks. ...you youngsters wouldn't know this but years ago in my mechanic days all fords came with Autolites....then suddenly 1 year motorcraft appeared...don't know who if anybody makes them for ford ...seems to be a big secret...maybe someone could chime in with more info. I at least would like to know. ??

Does anyone know which motorcraft plugs I need? For that 4.6?
