I've never even changed oil on any car I've owned so I was nervous about tackling a job like this. I didn't want to spend over $100 bucks for someone else to do it so I did a lot of research and ended up doing it myself.

I bought all of the tools necessary which included, sockets, nickel anti-sieze, aero-kroil, diaelectric grease for the COPs, gapper, etc...

I took my time and everything came out perfect!! The only issue I ran into was dropping the battery cable nut UNDERNEATH the battery holder which led to me romoving everything to retrieve it...grrr (my careless fault).

Once I put everything back together, I started the car up and it took a few seconds and then it started. After the initial startup the car actually starts faster than it used to - not that it really matters or anything. Car runs exceptional and no issues so far **fingers crossed**

I followed every instruction from the TSB to the T (amongst other references I found online) and it went flawless - let me know if you have any questions and don't be afraid to do this yourself.

Good Work Gus It's nice doing your own work on the car. You take more pride in the car

champion 7989's are the only 1 piece plug for the mustang in the stock heat range. I think Brisk makes a 1 piece that is 1 or 2 heat ranges cooler. I got mine from Summit for about $13 per plug

Glad you had success in changing your plugs. Nice job.

I have about 3000 miles on my Champions and no issues whatsoever. I took the car on a 500 mile round trip about 2 weeks ago and it ran flawless. Best drive I've ever taken.

Dorsil - I ordered them from RockAuto for about 10 bucks a plug with a 2 dollar rebate for each of them. I ordered 9 just in case I damaged one, etc...

I'm not sure the rebate is still available though. As of now, Champion is the only 1-piece stock repleacement and so far they're excellent.

According to the rebate, you had to purchase the plugs by May 31 and the rebate has to be received by Champion by June 30.
