Replying to: cobrass (Oct 22, 2008 6:10 pm) You bought a very nice motor car, but if it isn't broke, don't fix it.   The seller probably did the necessary to have it run very well so as to market it.

Replying to: Mr_Shiftright (Oct 21, 2008 8:53 am) AWSF-32P are no longer used. Ford is notorious for changing plugs. The plug was replaced with SP493. You would find that out when purchasing the plugs because the auto parts store would let you know that the AWSF was replaced.

Replying to: Mr_Shiftright (Nov 27, 2008 10:56 am) That's how I found out that the plugs were changed. It's best to tell the auto parts store the year and model of your car and that you want the platinum~Motorcraft plugs, they will tell you what the plug requirement is or call the Ford dealership. This forum is so so when it comes to specs. You were already given outdated info. The plugs in question fit my "99" GM but I don't know what the spec is for your year. "What's the best plug" to use relies on an opinion answer so I use what the manufacturer recommends. On my car the plugs are good for 100k.

Replying to: martykyj (Nov 27, 2008 7:05 pm) The info came right out of Alldata, which mechanics use but when I look at the Motorcraft site, that number has been superceded.   Motorcraft shows a variety of plugs for that engine actually, depending on what type you want and also depending on something called a "W engine code" which I don't know about. For that code they list a very similar number to the one from Alldata---AGSF32PM   SP493 seems to be a platinum plug for the Non W code engines.   Ford changes their plug numbers so often that by the time he reads this, there will be a new #   Replies to this message: martykyj (Nov 30, 2008 8:47 am)

My 01 MGM started missing at 94K miles and I installed the Bosch double platinum plugs I bought at Walmart. That was 22K miles ago and it has been running great ever since then.
