Is $23.00 good for a set of ngk tr55 platinum plugs? or is that to much?

Sounds like a good buy to me..

waste of money for platinums. platinum is a poor conductor which is why they last longer. buy autolite standards or NGK standards for about $1.30 each and you'll get better performance.

That is actually cheap for a decent platinum plug. For some reason, I have heard over and over again that platinums such as Bosch are not good for Mustangs. The longevity is there but not the performance. I use NGK "V" plugs myself. Steeda stocks tons of them for all Mustangs. If you want a newer, more innovative plug that I am seriously considering to buy, check these out:

Be sure to read some of the test data on these E3 plugs. Seems to add quite a bit of performance. And, no, these are not just another Splitfire repackaged. These are quite different. JC Whitney now carries them at about $8.99 a plug. I think you can probably find them online for around $5.99 a plug which is a steal compared to the Iridium type plugs that so many also talk about these days. Iridium's cost around $12.99 a plug!

This link will show you how much better the E3's perform over typical plug configurations:
