Default Spark plug removal

I now have almost 89K miles on my Z06. Probably time to change the plugs (LOL), even though the car runs fine.

I have fat hands and cannot reach around the metal protector for the plugs. And, I know if I simply pull on the wire, it will simply pull out of its holder.

Is there a special tool to remove these types of plugs ???

Any help is appreciated.

If you are approaching 100k mi, put some new wires with those plugs

Get the plugs wires too... I can guarantee you will pull At least one apart. I tore 3 wires up changing the plugs out... The plug wire boots melt around the plug after years and years, plus the wire gets really brittle too.. Its like trying to pull a tooth out of an elephant with pliars. Some of the boots came off fairly easy.. Every car will be a little different.. Have the proper tools also.. a plug wire boot puller and a swivel head socket make the job MUCH MUCH easier.. The number 7 plug is a real PIA... Gene Culley has the Red GM Hotwires for around 67 dollars... Best deal out there on a great set of wires....... You mentioned you have big hands... You will tear them up on # 7 I have small hands and they got all tore up, even after removing the air tube ... Wear some latex gloves at the very least

Careful with pulling the spark plug boots off with pliers. I had one on so tight that I had to pull so hard it began to rip/tear the boot.

As others mentioned- plan on replacing the plug wires and have them on hand.

Changing the plugs using the Snap-On triple jointed swivel socket was a piece of cake ( even the driver's side rear). It was the plug wires that at only 33K miles were a PITA.

I have an 02 Z with 41k on the clock. I see advertisments for plugs that suppose to give extra horsepower. Does it really matter what kind of plug you replace the delco's with or just stick with Gm plugs? Since plug removal is the topic I thought I'd just toss it out there.

I don't think anyone's ever gained HP from a spark plug/wire change. Recovered some of what might have been lost? Yes. Actual gains? No sir. I read a while back (when I was changing my plugs while doing my LT header install) that most, if not all, of the plugs that claim gains have been proven to be selling a whole bunch of

What you want is a reliable plug that you ideally won't have to check for another 50k miles.

Not true on any of the LS based motors.. Each plug has its own coil pack and every wire is the same size.. None of the wires cross each other and are not long enough to go from the designated coil pack to a different plug... Its pretty much dummy proof all the way... Not like the old days when we had a distributor to deal with and different sized wires.. Thats when you had to do one wire at a time..

I concur- not possible. Unless you have really long non oem wire and are stupid enough to cross wire ( the coil pack are per cylinder).

Spark plugs do not add HP- unless they have been incorrectly gapped or worn out.

Hate to be critical- but seems like a lot of super general questions are being asked about the most basic of maintenance items. Maybe better to take your car to an experienced mechanic if you aren't sure how to do the job. But heck-I've been a back yard mechanic since age 16 .

One very important tip: change the spark plugs when the engine is cold and at minimum set over night.

Default Spark plug removal

Hey guys, thanks for all the input. I replaced both the plugs and wires yesterday. I didn't use a plug wire puller. Old plugs looks almost brand new. I can't notice any difference in the performance.
