I just recently bought my car and so far I took care of just about everything (all fluid and filter changes). The plugs and wires are the only thing I never dealt with yet. Everything is running as good as I could ask for, should I still change the plugs and wires at this mileage? I am pretty sure they are the original plugs on there.

Just curious to what you guys would do.

I would. If you got the cash laying around it isn't going to hurt anything. Just get a good setup not some cheap wires and plugs.

Pull a couple easy ones from each bank that are easy to get too and see what's in there/how they look. You're probably fine if they're the stock plugs.

yes change them!! the stock platinum has probobly already shot through the exhaust by now, put some NGK TR55's or the TR55IX iridium those are great plugs, u can also go with the MSD 8.5MM wires those are good wires also, all this shouldent cost much

Byunspeed and 99blancoSS were running specials on their plug/wire kit. They were also cheaper than ws6store

Thanks for the tip, Z28/2002.

And yea, I know #8 is a bitch. Anyone know if they make a certain socket tool to make that plug any easier?

I just got MSD plugs and NGK TR6's shipped for 65 off the forums. Want a link to the seller msg me.

I am doing mine today and I want to know the same thing. All I have is a regular socket and wrench.

Can't hurt to change the plugs...but you will be completely wasting your money on upgraded plug wires. Your engine is stock'ish. You can't beat the factory wires for a stock engine. Upgraded Taylors or any other after market brand will give you absolutely NOTHING by way of better performance. Your factory wires will last 200,000 miles, easily.

If you do decide to get new wires however, just spend $36.00 and go to Advance Auto parts. I've been using them on my ~500 RWHP 427ci and they do just as good as the factory wires and they did exactly the same as my piece of **** Taylor 10.4mm Thunderbolts. Pulling them AT THE BOOT when I changed my plugs....5 of the 8 broke. They suck!!!! The clips got stuck on the spark plugs and pulls right out of the boot. And yes, I used dielectric grease so they wouldn't get stuck on there. Also, good thing I kept all 8 of my factory wires, I put them back on and the engine performed identical. You don't need upgraded wires until you're making near 600 RWHP.

#8 isn't too bad

needadvice

Here's what you need for the two back plugs on the passengers side. #7 and #8 plug comes out in 5 minutes and the new plugs go back in in 5 minutes. No tricks, all 8 plugs from the top, no moving coils or anything else. The rest are easy. The entire job, all 8 plugs, 30 minutes. You will need a regular sized ratchet for the drivers side plugs that are easy to get to, better leverage. And when you put the plugs back in just snug them a little bit, don't crank them in. I wait until the ratchet stops and then give it a little push and thats it. Use anti-sieze on the threads of the spark plugs.

Note*** the 1" long, 3/4 socket can be used if you need more room for some of the other plugs.

I say no to the plug wires too unless you pull the terminal off one.
I did a google search on wires and found an LS1 specific comparison. They listed the ohm readings of a lot of wires.
I got some of the better ones, but never installed them because my stock 2001 90,000 mile wires had less ohms than the performance brand.

On an LS1 you have no worry about crossfiring or wires rubbing against anything, so if the resistance is ok the wire is ok.

I use this with a 8" 3/8" breaker bar.

I have long SLP heads and 8 does not look easy from the bottom..

Also, I am about to start pulling them. My engine has been off for 4 hours is that long enough? The engine is luke warm I don't want to **** my engine up.

#8 is easy if you have a swivel head socket wrench with a long handle for leverage. A standard spark plug socket from any normal tool kit will work for it.

The trick is to remove the coil packs on the passenger side. Then #8 is accessible from literally behind the engine. You reach over the engine from where the coils were, then with the swivel head go towards 8 which is angled to the back. The longer handle will give the leverage needed to break it loose with the minimal space back there. Short stubby wrenches are just asking for pain.

Look for a long handle swivel head socket wrench.

Snap on has a good one, but I'm sure you can track one down at a local tool store.

This is a handy tool for LS1 work, I use a swivel head more than any other socket wrench I have.
