Planning a New Look......
07RT, how do you like the Iridiums?? Anyone else use the NGK Iridiums?? Are they worth the extra money??
They work great, but time and miles will be the true testto see if they were worth the extra $. Th original copper ones I pulled were still hangin' in there, so no substantial performance gain.07RT, how do you like the Iridiums?? Anyone else use the NGK Iridiums?? Are they worth the extra money??
I bought the plugs from rockauto.com and the anti sieze/boot grease from a local run car parts store. Great having them shipped right to the door for around $30 and picked up a few odds and ends as well.My Magnum has the originals and I'm at 63k miles now (50k miles in the last 25 months). I think it's time to change them!
What local parts store has these in stock and at a good price?
A little anti-sieze goes a long way. I just put a small dab on the leading edge of the threads. It gets spread around the rest of the threaded area as you install the spark plug and tighten it.How much anti-seize are you guys applying? Are you spreading it over all of the threads?
On the dielectric grease, I just give a small squeeeze of the tube to the inside of the rubber spark plug boot and then spread it 360 degrees around the inside of the boot using a smalll screwdriver. Just enough for a thin coat will do you just fine.How much dielectric grease are you using as well? Are you putting a small amount on top of the insulator?
With the anti size I would place a small dab on either sie of the plugs in the middle of the threads and spread it around with my finger. Just made sure a small amount was in the threads and no gobs hanging off.How much anti-seize are you guys applying? Are you spreading it over all of the threads?

According to the Service Manual: "13 foot pounds; not to exceed 15 foot pounds", for the 5.7L engine.Plugs are not torqued... if it has the little metal gasket it is a 1/4 turn past contact, if it doesn't and it just has a tapered metal flange it is 1/16 turn past contact. or snugged up as someone put it... haven't done mine yet but about to... hopefully get rid of the stutter I get sometimes...
Well... for the 5.7, the changeout schedule is every 30k, using Copper plugs.Very useful write up. I just finished changing the spark plugs on my 2006 Daytona. One of the simplest plug changes I've ever done. Not sure how it could have been made easier. That being said, it still took 1 hour and fifteen. There's a lot of twisting involved with changing 16 long plugs. I replaced the plugs with the exact same Champion type. I used anti seize and dialectic grease. I even set the gap and torqued the plugs, a first for me. I do have a couple comments, hopefully not offending anyone. I'm not sure how a few of you dropped screws when removing the coils. For my car they are the type of screw that remain in the coil pack (retainer type) when unbolted. Next comment is concerning the mileage. I was surprised at the low mileage a few of you changed your plugs at. Seemed like the 70s again. Perhaps shame on me for waiting until 110K miles to change them for the first time but the car has alway run so good I wrongfully assumed they were platinum plugs. The old plugs were all about the same with .060" gap. Don't get me wrong, I do believe in preventive maintenance which is why I changed my serpentine belt the other day.
