what would be the easiest possible to change the spark plugs and wires on a 94 z28?

Time & patience!

Lots of attachments and swivels...and what really helped is taking the alternator out. Also, if you have any wobble extensions, that's a plus.

Do a search too, there's plenty of info here.
Good luck!

The easiest way, would be to drop the engine out of the car.

Sadly this is almost true.

what he said...............unless u have headers, then its a walk in the park (compared to having stock manifolds that is, lol)

You will be able to access some from the top and the rest from the bottom. An assortment of extensions, swivels, and maybe an open end stubby wrench in conjunction with a spark plug socket should do the trick for ya.

the only thing as bad as doing the plugs on the stock manifolds was doing the wires in the stock location!

honestly, its not *that* bad. the first time it took me literally days to do (a few plugs each day after work). after having been through the ordeal once before, i removed them in about 30 min or less when preparing for my header install. its all about knowing how things fit - having girlishly small hands and arms helps a lot too. I didnt need to remove alternator or y-pipe to do any of my plugs. Make sure you use a plug socken and 19mm wrench.. there are spots where a ratchet wont fit.

trade your z in on another z that has new plugs in it

Ya, this is the way I had to do it. Plus I removed the alt. and tensoiner bracket. But I did the wires at the same time. I did not remove the exhaust, but thought very seriously about it.

if you are going to do spark plugs and wires, might as well throw a set of headers while you are down there.

It'll make things SO MUCH easier... I spent almost 2 hours just REMOVING them with manifolds... with pacesetter long tubes it was a 15 min job

i was able to get all the plugs and wires done without removing the alternator. the drivers side wires are easy and the passenger side is easy as long as you cut the original ones then route the new ones however you feel. all i can say is have patience and a strong will and you will suceed.
