Default [Removing/Replacing Spark Plugs] What Tools Do You Prefer?

[2003 LS1/A4 convertible, 52,000 miles, quite stock]

What tools does C5 Tech prefer for removing/replacing spark plugs? I've been using a 5/8 spark plug socket plus four inch extension plus flex head ratchet and it hasn't been very effective. I'll freely grant that I'm not the most skilled wrencher (I managed to cut/abrade my hand with gloves on yesterday while trying to get a plug out), so I'm looking for some suggestions on how to do this better.

I have one of these and it works good for removing the spark plugs, https://www.homedepot.com/p/Milwauke...FUa2swodZbAO0g.

I HIGHLY recommend removing the coil "pack" as an assembly, from the driver's side VC. Five bolts, one electrical plug. Leave the plug wires on the coils.

Don't forger a dab of "anti-seize" on the threads of the new plugs, as well as a dab of dielectric grease, on the insides of the boots of the wires.

I just use a 3/8" ratchet and a short extension (maybe 3"). Never found it difficult. Car has headers (don't know if that makes it easier or harder). I unplug the wires at the coils, slide the metal sleeve towards the motor as far as it will go, grab the rubber boot and twist, then pull.

I had 3 wires fall apart. Was very glad I had ordered a wire set with the plugs. Course, was about 113,000 miles on an '03 car. But, think the age had more to do with it than the miles. When I do my truck in a month or so with the 5.3 engine and 93,000 miles, also an '03 , I'll get a set of wires also.

A long handled flex head 3/8 ratchet, standard plug socket, and short extension are all I've ever needed.

Watch these videos, they are very helpful. Froggy is a good guy, has tons of C5 DIY videos. He recently upgraded to a C6 Z06 so he is starting to compile a library on the C6. The hose pullers/pliers he uses from Harbor Freight are very useful, making the job much easier. Use dielectric grease where advised. The #7 plug at the drivers side rear is the toughest. I would advise changing the wires at the same time with new as it is challenging not to damage a worn out spark plug wire when initially tugging on them. Good luck!

The only hard part about changing the plugs on my 98 was despite being relatively young, i have a bad back. So choose what ever tools you feel are necessary, but be sure you have some sort of comfy place to sit afterwards because leaning over these tiny cars is the hardest part, haha.

I fully understand what you're saying! Usually, a person receives only one "bad genetic trait" from their parents. For instance, my father's side of the family had bad teeth, while my mother's side had bad backs. Lucky me, I got both....

However, to address your point, with the Corvette being such a low car, yes, even a simple job like changing the plugs, can be tough on the back. Rolling the car up on a set of ramps can help the situation. While you don't need access to the underside of the car, the additional 3-4" the ramps lift the car, means that you don't have to stoop over as far, when changing the plugs.

I ordered plugs and wires. The #5 wire disintegrated when I (carefully) removed it—might explain the rough idle!

Swivel spark plug socket. All I removed was the air tube connection and no coil packs.
