DAVES89 Posted May 28, 2010 Share Posted May 28, 2010 I will be changing out the spark plugs on my red Reatta [60000 on old plugs]. I never changed them since I did the Delco coil pak upgrade. I haven't looked, but I am thinking that even the original gap of .045 should be close to .060 and need to be changed. So what plugs and gap should I go to?

padgett Posted May 28, 2010 Share Posted May 28, 2010 I use Rapidfire #14s gapped at .060" with the Delco ignition. 14s are available from Jegs or Summit if you have trouble finding.In theory you could regap #3s to .060" and have the same thing Link to comment Share on other sites More sharing options...
DAVES89 Posted June 2, 2010 Author Share Posted June 2, 2010 I went to Advance on Mon. and tried to buy the rapid fires. They only had 5 so I bought the platinums. I found I had purchased platinums before and installed them at 117000 miles. I now have 173000 miles and the gap on the old plugs were .065. I also had to do the wires as I broke one [#6 cylinder]. I had to go back for the wire set. My wife asked if it could wait until Tuesday. Bless her heart, she wanted to go biking, but I needed the car for Tuesday so I just bought the set and did the wires early Tuesday, before leaving for appointments...

padgett Posted June 2, 2010 Share Posted June 2, 2010 For plug wires, the Delco wants at least 8mm.This time of year we try to get things done early also - before 90F. Link to comment Share on other sites More sharing options...
