Great Forum! I recently purchased a 94 STS and have used the information in this forum to help troubleshoot a few areas. The STS is an amazing car! I am in the process of tuning up this car and would like to know which spark plugs to use. What gets the best bang for the buck so to speak? Also any info on wires would be great. Thanks.

i downgraded to autolite coppers on the advice of an engine builder. The car runs better than ever and has just a little bit more power.

not to mention they are $0.99 each compared to $4.50 each for the oem platnums
