Replacing plugs...need advice
i am replacing the plugs, wires, distributor cap and rotor on my 1997 1500 5.7L...Does anyone have any advice for me before I start. Am I going to run into any common problems or is this pretty straight forward. Can i take out the plugs without removing anything else? What brand parts should i use? anything that can help...THX

You should be fine with AC delco plugs. Brass inserts on the cap would be nice. I would not waste my money on a cheap set of wires. You can find a good set on Summitracing.com or many other mail order companys. If you do that you might as well get all the parts through them. Names to look for would be Mallory, MSD, Jacobs, Taylor, Accell, Look for a good 8mm wire. Anything bigger wont fit in your stock wire looms. You can also find a ignition tune up package which contains all the parts you want. Go to summitracing.com and ask customer service (through email) the part number for a good tune up kit. They have good service there.

Re: Replacing plugs...need advice
Please, PLEASE, do NOT use Bosch plugs. If you do you are asking for problems down the road. I have seen alot of Chevrolet vehicles that have bosch plugs in them and they usually have drivability issues. Stick with OEM, IMHO.

Re: Replacing plugs...need advice
I agree....Don't use Bosh. They break very easily. Don't bother with the wires unlessed they are broken, or the boots are cracked. GM stock wires are good ones. If you get new GM wires Be prepared for the $100 price tag.
If you remove the air filter asembly you'll have a little easier time. P.S Check the plug gaps on your pre gapped plugs. I checked mine in front of the Nappa guy, and the first one was .005 off.

pretty easy to change this stuff. Check your gap on all the plugs.Ask the store for proper gap.Take your time and mark your wires and know your firing cycle. (check your manual) I like to mark on my distributor cap what wire goes where.
Don't use bosch plugs. They don't work well with anything other than volkswagen. These cars actually call for them as replacements. I personally like NGK and have no problem with any vehicle I put them in. Have fun.

Bosch spark plugs are only good for European cars.Do not put Champions in,I have heard of Chevrolets not starting with Champion spark plugs installed.Ac Delco is the best spark plug for GM vehicles.For plug wires,stay away from these two places:AutoZone(really called AutoJunk) and Advanced Auto Parts.They sell the cheapest plug wires and cheap plugwires are not the way to go.Carquest Autoparts makes very good "top of the line" plugwires.My father puts in Carquest plug wires with no comebacks.Change the fuel filter also,it is a part of a tune up

It's easy to strip the dist. screw holes. be gentle.
and remove any old thread tite that was in there or you will bind on way in and crack cap or strip holes. Most say and I agree OEM best for this stuff. I didn't bother with the wires cause they were $100. I'll wait. The OEM AC Delco Platinum plugs worked very well for me. Don't believe the guys that tell you the cheap stuff is the same. The fuel filter is important & easy. Grab a PVC valve for a couple bucks while you're there
