I am looking to replace my spark plugs this weekend. I have been doing some online searching, including searches here on the forum.

In your opinion, what Spark plugs do you find the best 'bang for the buck'?

And any ideas, thoughts, or tricks as to how to tackle getting the plugs on the back side of the engine next to the fire wall?

I wouldnt use anything but AC Delco/Motor Craft. The quality is very good.

Regarding the plugs in the rear bank they're really not that hard to access.

Just get a universal and a couple of extensions, remove the little plastic canister and it's bracket and you should have direct access to all three plugs.

We've been using the Autolite 3924 and haven't had any issues with them. I know some people are more particular about it though. I think it was $12 for 6 of them.

I've done plugs with the intake on before but I think from now on I'm going to remove the intake to do them. My track car on the other hand has a ton of stuff out of the way so doing plugs and wires is a snap with the intake still in place. I just don't like scraping my hands up so much and hardly being able to see what I'm doing JUST for spark plugs anymore.

I think it's a lot easier to do the plugs without going through all the work to remove the intake (not that hard, but time consuming for a job that shouldn't take more than a few minutes really). On my car it's a bit of a pain because of the strut tower bar but I got more scrapes on my hands pulling the intake (and then having to put it back on) than just pulling the plugs would've done I think.

e3 plugs are awesome. really make the secondaries pop.

Did you try out any other NEW spark plugs before the E3's, or did you just replace your old, worn out plugs with them? You can't claim that they make an improvement if you haven't tried anything else.

I use the Autolite double-platinums, part number APP3924.

What he said...whichever is priced best.

When installing, blow out the plug wells with compressed air before you remove the plug to keep debris from falling into the cylinder.

Plugs

Bought my 1990 MTX in 09/2009 w/ 95K miles. I changed the motor oil, tranny fluid, fuel filter and all 4 struts and went on a 2k mile trip to Mt Rainer and she performed wondefully. Got back and pulled my spark plug boots to find ever hole full up to the resisitor with oil. Did the 60K upper and went right back with AGSP32PP that I find online because I figured if the original plugs lasted 20 years and ran that good filled with oil and with the original motorcraft wire set it would be worth the $8 a piece I spent on them, oh I changed the spark plug wires too

If you go to Autozone, they sell a spark plug socket permanently attached to an extension bar via a ball socket so it swivels. It's made by Great Neck. It's also magnetized and that helps out a lot. It makes changing the rear bank a breeze.

As for plugs, I use the Bosch Platinum +2's.

If your valve covers aren't leaking into the plug wells, and you don't plan on changing wires, it should take no more then 10 minutes or so to change all 6 plugs with the intake in place. Like it says above somewhere, remove the bracket holding the vacuum reservoir to the back of the intake, and it's magically easy. I didn't believe how easy it was the first time I did it. And yes, I have a fancy magnetic spark plug socket set with the extensions permanently attached.

I'm on my 2nd set of Motorcraft AGSP32FM (fine wire) plugs, with AC Delco wires, and have been very pleased with the overall performance. Over 68,000 miles and no problems. You have to remember to look at plugs and wires as a set. You can have the best plugs combined with marginal wires, or vice versa, and you will still be burdened with ignition problems. :salute:

I'm running Motorcraft FMs along with Duralast wires.Taylor Thundervolt 8.2s are trash.

We've got the Taylors on two of our SHO's and they seem to be great. And no, I didn't see a "design flaw" of the first connector being shorter. If it is, it seems to be a subtle difference.
