So I'm changing out the plugs on my stock 2.8 and I have no idea how I'm suppose to get the plugs in the back out. Anyone know a simple way of getting those plugs out?

https://www.fiero.nl/forum/Forum2/HTML/118492.html

I also recommend NGK spark plugs and lots of patience.

Stick with AC Delco plugs...

Another one of those jobs where I say "I don't get it"...I'm a short, fat guy, and I did all 6 plugs in my Formula in less than an hour, without removing a single part other than the plug wire off the plug, and the plug out of the head. Standard plug socket, couple of extensions, and a standard 3/8" ratchet. Put my feet in the truck, and sat on the rear of the trunk over the tail lights for the rear three, and laid on top of the intake for the firewall side three. Hardest part was pulling my fat arse off the intake a few times, lol.

I simply remove the passenger side vent, that allows you to get to the passenger side rear plug, then get in the trunk and lean over the top of the engine to reach the other two plugs. It takes a little feeling around and a perfectly matched ratchet extension but not a bad job at all.

You need to include the "rust belt" factor. In bad weather, those 3 front plugs get junk and corrosion and who knows what in the pocket in the casting, to the point where you may not get a wrench on the plug. Arizona and Georgia are not going to give you the problem.

Maybe not Arizona and Georgia but I had a Florida car in South Carolina that was virtually impossible to change the forward bank of spark plugs due to rust/corrosion around them. I ended up dropping the engine and replacing it with a V8. Now it is some other person's problem.

Now you have 2 more plugs to worry with, kind of drastic way to change your spark plugs. LOL

Yeah... get a pick and some PB blaster. Soak the plugs for a few days, clean out around plug with pick, soak again... repeat. The more you can clean out by the threads, the better chance you have. Of course, the plug could be rusted through and ... well... Hopefully they come out

Sometimes they come out fine, sometimes they don't....sad to say.

AC delco plugs, this project gave me rug burns. not next time and no rust in my trunk.

I am telling you, NGK are by FAR the best plugs available for our cars, and they blow Delco out of the water.

I lol'ed

I just did my plugs last weekend. Pulled the wire caps, removed, replaced. Took about 45 minutes. Normally I am all thumbs with automotive stuff, but this was very straight forward.

Best of luck!

On a side note, I asked for ac delco, because that's what was in there, but I got ngk instead as it was recommend by checkout guy at the store & the ac delco was out of stock.

ok - not to hijack this thread but old lar and jim and blackemrald have stated their choice of spark plug.
my question is why are ngk better than ac-delco and vice versa - is it a personal choice or is there a performance gain.

I'd be happy to explain why I think NGK is better than AC Delco.

First, Here is links to each plug: NGK NGK-2771 vs. AC Delco ACF-R42TS

If you want to compare there is a link. But basically, they use the same technology with a copper core and a nickel alloy for the tip. The big difference is quality. The NGK plugs are made in Japan with high quality materials and to a higher standard. AC Delco, on the other hand, are made in Mexico (sometimes). The way AC Delco (and Motorcraft for that matter) products are made is by contracting out the manufacturing contracts to the lowest bidder. So AC Delco plugs may be made in Champion factories one year, then Autolite, then Bosch, ect. Inherently, this undermines the over all quality of the plugs year to year. You may see variances plug-to-plug depending on quality control standards at that manufacturing facility.

The heat range of the AC Delco is just 2 while the NGK is more than double at 5. This means there is more consistency, and higher temperature of the spark. This does not necessarily mean performance gains, but it will make your car run smoother and react better to other performance parts in your ignition system (like your coil). By running more efficiently, they put less of a draw on your ignition system, harnessing the full voltage more effectively.

Also, it is my personal experience that AC Delco corrode more easily because of the coating they put on the threads. Long term, this may mean they rust making it more difficult to change and may even break off. The NGK's have a Chrome-like coating on the threads and bolt head that resist rust and corrosion better but doesn't guarantee no corrosion.

The downside: Yes, the NGK's cost more. They cost $.50 to $1.00 more per plug than the Delco's but I believe you get what you pay for. For just a buck more per plug you could get these. They are Platinum-tipped and should last longer and provide even smoother and more efficient engine performance.

I hope this answered your question, and if you have any other questions don't hesitate to ask!

thanks blackemrald - very good explanation and theory on the lowest bidder i.e factory to factory is definately going to make a difference - when my plugs are due for a change I will try ngk just to see if there is any improvement
if it is true (not saying anything against you) then the extra $1 per plug is worth the investment.

thanks again

Best to change plugs every couple of years as those front set get bathed in water in the rain and corrode in place.

V8s are easy to change from under the car. I could put a set in mine in less than 20 mins.

This old thread again? Yes the NGK are great plugs. But the 80s ECM sure doesnt like them. Put Delcos back in and host of engine hiccups went away.
Just put anti-seaze on the spark plug threads and dont leave them in till the next Mayan holiday. And if required a chiropractor visit afterwards.

Where is the "Like" Button for this when you need it?

I'm sorry you haven't had luck with NGK. I have been running NGK in mine fore 2 years with Taylor cap/rotor and Taylor thundervolt 8.8mm wires with stock coil. The difference is night and day.

Sounds like you may have other issues that need attention if your car didn't run well on them. Were they gapped correctly? How old is the rest of your ignition system?

Good luck!

NGK is best left to bikes. Im happy your NGK plugs are working for you but there have been tons misses caused by crap plugs such as NGK and Autolite. If you can tell night and day difference from a simple plug and wire change then you should have taken better care of your car
have nice day
